RV Toilet Repair – How To Fix That Problem Toilet

rv-toilet-water-in-bowl.jpg Under normal circumstances, the toilet in your RV retains water in the bowl.  The most important reason for that water is to block odor from coming up into the living space. 

The proper method of use in an RV is to hold the water valve open after flushing to allow about an inch of water to sit in the bottom after the valve has closed. 

When that inch of water mysteriously disappears awhile after flushing it’s an indication that the rubber seals around that large valve have gotten hard or damaged and are no longer doing the job.

Aqua Magic RV Toilets

Aqua Magic toilets produced by Thetford are the most common toilets found in all but the most expensive of RVs. 

There are a few other brands, including some that are ceramic and similar to what you find in a home. 

If your RV cost less than $100,000, odds are pretty good you have a Thetford Aqua Magic toilet.

One nice feature of the Thetford RV toilet is the fact that Aqua Magic parts are readily available. As a result, repairing rather than replacing the RV toilet is a common practice. 

 

What Can Go Wrong With An RV Toilet?

The RV toilet is a straightforward device with pretty much only 2 areas that may cause you any problems:

1.  The blade seals for the wide valve at the bottom of the bowl — explained above.

2.  The water valve — water continues to run when you release the water valve control handle (or pedal, depending on your model).

Of course being that the whole toilet is plastic, if you happen to break any parts, you will find most are readily available. 

Mark’s RV Supplies is one of many companies that carry almost anything you would need to get your RV toilet back in operating condition.
 

How To Repair An RV Toilet

To repair your RV toilet, follow these steps:

  • The first step is to turn off the water pressure — either by turning off the “City Water” valve or turning off the on switch for the on-board water pump.

  • Flush the toilet to bleed off any remaining water pressure and to empty all water out of the toilet bowl. 
  • The toilet will have to be removed in order to work on it, as repairs are made from the rear or bottom side. 

  • Remove the 2 bolts (one on each side) that secure the toilet to the floor.  You’ll then be able to lift the toilet away from the wall and access the water connection at the back side of the toilet.  With the water line disconnected, you can then remove the toilet to a nearby work bench or table.

  • You might want to lay a cloth rag across the hole to help keep odors at bay, and to prevent anything from falling into the black water tank

  • Unlike house toilets, RVs don’t use a wax ring to seal the toilet to the drain pipe.  Instead, you will have a rubber ring that will act as the seal. 

  • Depending on what portion of the toilet your repairs are concerned with, refer to the parts diagram that comes with the repair kit for disassembly instructions.  Be sure when you order parts for the specific brand and model number of your RV toilet.

  • If you’re repairing the blade seals, before you reinstall the toilet in the RV, pour a quart of water into the toilet to make sure the new seals will hold water. 

  • If you’re replacing the water valve on the back of the toilet, once you have reinstalled the water line, pressurize the water system to make sure the valve doesn’t leak.  If it passes this test, then go ahead and bolt it back down to the floor.

  • It’s recommended that you install a new rubber seal between the toilet and the floor flange when you reinstall the toilet.

Toilet problems can really put the damper on a good RV outing.  Fortunately repairing them isn’t really as bad as it sounds.  The stinky part stays in the black water tank.

    I have a Thetford Aqua-Magic V toilet in my RV. Recently, we have experienced a reduced pressure of water entering the bowl before a flush. I don’t think I have a blocked water source. Other faucet pressures are fine. Is the water module/valve my problem?

    • Dan

      I’m having the same poblem. do you know what it is ?

      • Curtis

        Dan, It could be the water valve or some plastic or grit has found its way into the valve partially blocking it.

        • http://www.facebook.com/EllendenDulk Ellen Den Dulk

          That is what happened to my toilet too, right before the valve broke.

  • Curtis

    Ron, It could be the water module valve, or possibly a linkage problem too. If the valve is unable to open all the way either from internal damage or the linkage not working properly you could have low water flow. This parts breakdown http://www.marksrv.com/am5_parts.htm
    shows the water module as the only valve controlling water flow so I think your on the right track.

  • Ron

    Curtis,
    Thanks for the reply. My model # on that Aqua-Magic V is 31683. It is a hand flush/High model with no hand spray. Is the parts sheet you emailed the correct one for that model specifically, or do all of Aqua-Magic V’s use the same water module/valve?

  • Curtis

    Ron, I only have access to what I can find on the internet and all I did was search on the Aqua-magic V. For more specific information you’ll have to call an RV dealer.

  • Anonymous

    the water valve behind the toilet leaks when I flush the toilet. Can something be tightened?

    • Curtis

      Shadetreej, Not likely, the valve and all connections are plastic. Best bet is to remove the toilet so you can see what’s going on. Might be a cracked fitting, or the water valve may be shot.

  • tim

    • Curtis

      Frank, virtually all repairs will require you to remove the toilet from your RV.

    the pooper in our RV doesn’t work. the yucky stuff is stuck somewhere and won’t empty or go down. now bowl stinks and no one can use it. have any ideas how to fix this problem??? thanks, hope you’re having a fun day! Lola

    • Curtis

      Lola, you’ll have to be much more specific as to what’s going on. When you attempt to flush do you see waste material below the toilet? Has the tank been flushed out? Has the water drained off but the solid matter has remained in the tank? The more information you can give the more accurate information I can give you.

    How do you remove toilet flange from a RV. The problem is there is no access to the rubber coupling that connects the pipe to the waste tank! The question I have is does the flange fit into the pipe or is the flange & the pipe one piece that connects to the tank. This is a 1991 Winnebago warrior! I need to remove this so I can repair some water lines

    • Curtis

      Every manufacturer and every model may be different. Sorry, I have no way of knowing. If you are repairing water lines another alternative might be to run new water lines through a different more accessible route and abandon the ones that are hidden where you can’t get at them.

    Hi Curtis: the water pedal goes down and water comes out, but the water doesn’t stay in the bowl. The pedal that slides the blade doesn’t go down, so the blade doesn’t slide to open up (it gets stuck). Since this happened on day 2 of our recent camp out, i improvised by using a stick to put pressure on the blade while pressing the pedal, which allowed the blade to slide open. Do you think i need to replace the blade spring, the blade seal, the blade track, or the actuator? Or all 4 components?

    • Curtis

      Hi Edward, I can only give you a definite maybe without seeing the parts up close. The most common cause of your stuck slide problem is the buildup of material in the track is preventing the slide from opening or closing completely. This will let water slowly leak out of the bowl and make it difficult to operate the pedal. I’d recommend removing the toilet so you can do an up close inspection of all those parts and determine if there is any damage or if it just needs a good cleaning.

    Curtis, I have a Thetford Aqua Magic, Starlite. The water drips. Very constant, drip, drip, drip. Just started after a trip in March, 835 miles. Would you give me repair suggestions and explain the problem. Could the water line be leaking or is it something else such a the valve??
    Thank you.

  • Shara Lewis

    Hi — We have a problem with our camper toilet. When you flush it you can see waste on the sides before going into the tank. I called Thetford and they really had no answers and say the guys who developed it said nothing would stick to it!!! That is completely not true!! Do you have any suggestions on how to clean this without having to take the toilet out?? I know we’re not the only ones to have trouble with this, especially full-timers like us. We are even considering installing a PVC pipe or something to keep waste from going into all the crooks and crannies. Thanks in advance for your help.

    • Curtis

      Shara, If I understand your problem correctly your issue is solid waste sticking to the side of the toilet bowl. The best way to avoid this is to not be stingy with the water. If the bowl is half full of water before use the material won’t stick. This is the best approach to avoid build up of solid waste in the tank or pipe going to the tank as well. RV toilets aren’t meant to be used with little or no water. If your problem is in the pipe below the toilet it’s time to break out the garden hose and flush out the tank.

  • Greg Loesch

    After I de-winterized my 27 foot travel trailer the toilet will not flush. There doesn’t seem to be any water going to it. When you hit the flush or rinse handle nothing happens. Even when I hold the handle open there still is no water to flush the toilet. Water runs to the bathroom tub and sink, but nothing seems to go to the toilet. Is this a bad water valve that I can replace, or do I have a more serious problem. I will await a response before I start tearing out the toilet if I don’t have to.

    • Curtis

      Greg, Without the make and model information generally there is a water valve that can be replaced. This link will show you an exploded view of an Aquamagic 4 toilet to give you an idea. http://www.rverscorner.com/aqua4.html Before you settle on the water valve or the linkage related to the water valve make sure water pressure is getting to the toilet. Partially loosen the fitting going to the toilet then momentarily have someone turn the water pump on while you watch to see if it leaks water.

  • Kendra

    We have a Thetford Aqua-Magic V toilet in our trailer and we can get by on two days use, however, that second day we begin to leak water around the valve fitting. We have tried taking the fitting off and placing it back on (thinking that it has been cross-threaded). No luck it has happened to us again on our last outing. Any ideas? I am going to try to relplace the clamp near the fitting and the cone washer. Do you think that this repairs will correct the problem?

      Kendra you might try using some plumbers teflon tape to help the threada on the fitting seal better.

  • Sam & Jean Davis

    Curtis, I hope you can help us with a RV bathroom toliet problem we have – we have a RV Toliet Magic V with a foot pedal flush by Thetford in our 2010 Flag Staff 5th Wheel trailer. After we flush it we press gently on the pedal to add water back into the bowl, and almost everytime we readd water to the bowl it begins to leak back out. It doesn’t do it every time, it just seems if we add too much water. Are we just adding to much, and what is to much, or do we have a problem and how do we fix it? We are new 5th wheel campers, and have not had a problem free time with the camper. But that is a different story. Right now, I hate going up the stairs and finding water has leaked out of the toilet, and headed for the floor vent in the hallway. Thanks much for any help you can give us. Sam & Jean Davis

    • Curtis

      Sam & Jean, As I read your question I got confused by the last sentence. If the water is leaking out (going down the drain) leaving your toilet bowl empty, you have a problem with the blade seal at the bottom of the bowl. It could just be toilet paper trapped in the groove it travels in. If you mean water is running over the top and down the side of the toilet you have a problem with the water valve not shutting off properly. Here’s a parts break down link that may help you chase down this problem. http://www.thetford.com/HOME/PARTS/PermanentToilets/AquaMagicVFootFlushPartsNEW/tabid/619/Default.aspx

  • Brianescandon

    Hello Sir.,.,., I have a aqua magic style II toliet in my coachman wyoming fifth wheel., The waste ball broke and im trying to replace it., Ive got the toliet all taken apart and i even pryed the broken waste ball out. I can see where the end of the waste ball broke but cant get it off the waste ball drive arm. it seems really stuck. SO i try and take the shroud off the pedal flush to get to the drive arm and get the little broken peice of waste ball off the end of it. but i can’t seem to remove the shroud. The directions say push pedal down and remove the 2 o rings holding the shroud on. However i cant seem to see any o rings., just two peices of plastic and one can be loosened by lifting on a plastic tab that holds it on. the other(which is the other end of the waste ball drive arm) isnt really holding on to the shroud. Itsa the spring that seems to not let go of the pedal shroud. Please help., Now i have the toilet off and my wife cant use the bathroom. Thanx A bunch.

  • HLH

    Hello, we have a 2010 Keystone Laredo Travel Trailer. We are new campers and so unfamiliar with the “repair” issues. We are having issues with the toilet/pump working. It has worked fine up until last night we filled the camper to go out this weekend and we have the pump on, and I always run water in the faucets/toilet etc. once we are done filling with water. However when you push the pedal on the toilet…no pump sound or water running into the toilet. Confused on what to do or where to start looking. thanks for any help!
    HH

    • Curtis

      HLH, You didn’t mention whether or not your sink faucets are working as well. If not it is an indication the problem lies in the pump. Anything from a blown fuse or dead battery could be the culprit. If the only water related mechanism that isn’t working is the toilet then you could be looking at a bad water valve or linkage issue between the pedal and the water valve. These are just some general ideas of where to start looking, good luck.

  • Danielle

    We have an older tent trailer with a Thetford Electra Magic recirculating toilet… absolutely no problems with it until just recently.. push button to “flush” and it makes noise but water does not rinse the bowl as usual..

  • Mark

    Hi Curtis, I have what appears to be a Sealand Traveler in a 2009 Montana. There are no booklets or paper work on this toilet. The water seeps out of the bowl. I tried cleaning the ball, also wiped the o-ring that the ball seals against. There is no debris in the area, but it water still seeps out. Short of buying a new toilet is there any hopes of repairs?
    Thanks

  • Newenglandguy

    Hi Curtis – we had a little incident where our guests didn’t check the flusher on our RC Thetford Aqua Magic IV toilet and by the time my son found it there was water running out of the floor. It doesn’t appear the water came over the top of the bowl, so I’m not sure where it came from. The tank was topped out, so is there a way it can come out of where the toilet sits on the floor?

    My main concern is if I have to replace the flooring, or can I just dry it out good.

    Thanks

    Jim

    • Curtis

      Jim, Pretty much the water did overflow and come out the top of the bowl. I’m not sure what you mean by the tank was topped out though. As for the flooring time will tell. If you managed to get it completely dried out very soon after the spill you’re probably alright. If the water soaked into the wood it may destroy it and a soft spot will develop.

  • TonyD

    Hey Curtis,
    My toilet is leaking from the back when you flush.. just below the lid. So in the upper portion.. do you think this would be the water valve? Or possibly a fitting in that area?

    • Curtis

      TonyD, Sounds like you’re on the right track, that’s where the water valve is located.

  • Bruce Browne

    We are having a problem with the pedals. Last time we went camping our toilet seemed to cause the carpet to get very wet. When we used the pedal for the water and flused it made the carpet wet around it.

    • Curtis

      Bruce, Actually the pedals operate the water valve. You may have a loose or cracked fitting at the water valve.

  • Maurie Sumption

    Hi Curtis,

    We’ve had a (2009) fifth wheel for two years now. All of the sudden we’re noticing HEAT coming up through the toilet when we flush. The tank is emptied (correctly) prior to every move. We’re noticing it early morning as well as later (before the day heats up). Is this normal (part of the breakdown with the chemicals)?

    • Curtis

      Maurie, That’s a new one on me… waste decomposition would create heat, though I can’t imagine it would be enough that you would notice it coming up through the toilet. One other thing comes to mine, are your waste tanks equipped with electrical heaters? My motorhome has what looks like electrical heating pads attached to the bottom side of the waste tanks that when turned on will keep the tanks from freezing. If they are left turned on in non-freezing weather they may heat the tank enough to experience heat coming up through the toilet when you flush.

  • russell wallace

    how do you pop the top of the toilet to get to the bolts to take out the toilet

    • Curtis

      Russell, The two bolts are one on each side down by the base. They’re covered by a small plastic cover that just snaps in place. You don’t need to disassemble the toilet to remove it.

  • Kftf

    Just recently, when we attempt to partially depress the pedal to add water, the blade immediately opens. Normally the pedal is depressed halfway to add water, then all the way to flush. Is there an adjustment for correcting this? Thanks

  • JacintoKid

    Hi Curtis, I have an Aqua Magic . My first symptom was a leak on an outside drain valve for the toilet. (drains the fresh water from toilet to the outside). At the same time, the toilet developed another problem. When I pull the hand lever to fill the bowl, water flow is very limited (maybe 1/5th of normal) and it hisses (so, air is shooting out) The pump only runs intermittently rather than continuous. The other faucets work and the pump runs continously as it should. Any ideas? someone suggested backflow problem. Thanks, Brad

    • Curtis

      Brad, Your symptoms just don’t add up. Nothing about the Aqua Magic is air powered so I have no idea what would be hissing. I’m not familiar with any kind of an outside drain valve for fresh water in relation to the toilet either. If you have an obstruction in the water line, or if the water valve isn’t opening far enough the pump will only be able to run intermittently. Maybe that restriction is causing what you think is a hissing noise, but probably is water trying to get past a restriction. A kinked water line could cause that too.

  • Mitch

    Curtis, I have a 1985 Prowler. Just bought it last week. When I connected the water hose ( i used a pressure reducer) and pressured the system up, water started running out from the base of the toilet. Could it be a leaking connection on the waterline going into the toilet?

    • Curtis

      Mitch, Yes it could be the water line feeding the toilet, or the water valve, or a fitting related to the same. Odds are it isn’t a cracked bowl, or structural issue and likely it isn’t the rubber seal between the toilet and the drain pipe. I’m guessing the trailer wasn’t properly winterized and freezing temps cracked something.

      • Mitch

        I appreciate your feedback. I will pull the toilet and pressurize the lines to see where exactly the leak is coming from. Would that be the right way to determine where the leak is coming from?

        • Curtis

          Mitch, you’re on the right track. That’s the best way to find out what’s going on.

          • Mitch

            Thanks again.

  • Bradbury Waltdeb

    Hi Curtis, I’ve just put a new blade seal in our Aqua magic IV RV toilet and it is going to be stored for the winter (in Canada) should I use some kind of lubricant on the blade seal so it won’t stick. Walt Bradbury

    • Curtis

      Waltdeb, I live in northern Minnesota, similar winter climate I’m sure. All I have ever done is leave a small amount of RV antifreeze in the toilet bowl. Grease and some rubber seals don’t always get along, swelling or distorting may take place. RV antifreeze offers moisture that won’t freeze. I think that is the best way to go.

      • Bradbury Waltdeb

        Thanks Curtis, That is exactly what I have already done, I just thought there might be something better. I’ve been through Minnesota its beautiful country, hope you have a grear winter. Take Care Thanks again

    Hello Curtis, I have a inverter that my cat pissed on. It now does not work properly as it doesn’t even come on. Could this be because of the piss from the cat? The inverter stopped working as soon as the cat was relieving herself on it. The inverter is a heart interface 2000 watt. Thanks

    Any ideas it’s in a 2003 jayco I’m not sure of the model number.

    • Carpercb

      Wgeirrine, It sounds like either a water valve problem or a linkage problem. You’ll have to remove the toilet to do a bench disassembly to find out which.

  • Echo

    Hi, sure hope you can help! My daughter and I own and live in a 1983 Fleetwood Cimarron Wilderness 28′ travel trailer. Yeah it’s old and has repair problems but it’s home for now.
    Lately when flushing the toilet with the foot valves the water does not stop filling the bowl. It’s not a quick fill but a very slow trickle. It has gotten to the point that if we plan to be gone a couple of hours we turn off the water supply to the trailer before we leave. I have no idea on model number and as yet haven’t found one either. The closest we can come is it’s a Aqua Magic SL (low).
    This is our first RV and to be truthful I have no idea how to work on it as yet, tho I do believe I’m going to be learning real quick. Money is an issue thus the need to learn and do myself.
    Any help would be greatly appreciated….. Thanks

    • Curtis

      Echo, This link will take you to Thetford’s site. http://www.thetford.com/HOME/PARTS/PermanentToilets/AquaMagicGalaxyPartsNEW/tabid/615/Default.aspx
      You will have to remove the toilet to work on it, hopefully this parts breakdown will help. If it isn’t the correct toilet go to their product list and maybe you can find yours. It looks like yours may be no longer made so finding parts may be hit or miss. As old as it is you may still be better off just buying a new toilet and installing it yourself. It’s only two bolts and a water line so you can save the cost of labor by doing it yourself.

      • Echo

        Thank you so much for answering! I was somewhat afraid that I would need to buy a new toilet. But then again a new one will last a very long time! And in the long run would probably be a lot easier and smarter to simply replace the old one.
        Thanks again…….

  • Ruth

    We bought a new tolet three years ago but now will not hold water because the blade that opens when you flush will not close all the way. It is like living in an out house now. what can be done to get the blade to shut all the way.

    • Curtis

      Ruth, there may be material (toilet paper) built up in the track that the blade rides in. Carefully cleaning the groove may help. Otherwise you will have to remove the toilet to get to the workings to see what is causing the problem.

  • rUTH

      Jbbug55, Your toilet is probably repairable unless the track the valve runs in is physically damaged.  Generally the problem is toilet paper has gotten wedged into the track so unless you have taken to forcing the flapper with mechanical devices you probably haven’t damaged it.  You will most likely need to remove the toilet to facilitate disassembly to clean the track.

  • Candsphilp

    my pedal sticks on fully open  I cleanded and sprayed cleaner all around the fittings but it still sticks open sometimes

    • Curtis

      Candsphip, The first red flag that comes to mind is “spray cleaner”.  The seals may have swelled some in a reaction to the cleaner that may not have been compatible with the toilet mechanism.  This is the kind of repair best done on a bench with some disassembly required.

    I own a 1996 Nomad, 19′ 5th wheel ( just a little guy). Recently I’ve developed a purple stain around the base of my toilet that has spread outward staining the vinyl floor about 4″ in front and to each side about 8 to 10 inches. My guess is somehow the treated material in the black water tank has splashed back up while in transport and leaked out onto my floor and discolored it. Is there a seal around the base of the toilet that has gone bad that could have allowed this to happen? Any advise you could provide would be greatly appreciated. Al

    • Curtis

      MichiganderAl, Yes there is a rubber o-ring type seal between the toilet and the pipe leading to the black tank.  You will have to remove the toilet to replace the seal.  The toilet is held in place by 2 bolts similar to a house toilet.  Do not attempt to use a wax house type seal, it will just make a mess.  You can get the correct seal at any RV dealer.

    Our RV toilet does not dispense the water evenly around the bowl.  The front part doesn’t seem to let any water out.  Consequently it always has a bit of a nasty odor lingering!  Tried to spray some CLR up into the holes but didn’t seem to help!

    • Curtis

      Colibrit12, CLR is a pretty strong stuff, plastic toilets aren’t designed to be cleaned with harsh chemicals, it’s unlikely that minerals have built up and plugged your water ports.  Find a fine wire and use it like a pipe cleaner to check the small holes and if that doesn’t do it you have a water pressure problem that could possibly be caused by a faulty water valve not opening properly or something else.  Pretty impossible to diagnose exactly what’s happening over the internet.

  • Jeff

    My parents have a Jayco “J” travel trailer.  The Aqua Magic IV toilet has a leak.  When you pull the tabs for the toilet to flush or to add water, water pours out the back.  Not sure where exactly it is coming from.

    • Curtis

      Jeff, Likely the water valve or a fitting to it is leaking.  You’ll have to remove the toilet to investigate the problem.

  • SMITH731

    We have a 1976 aristocrat trailer, electra flush toliet, no water going in, no power to the swith, are they 12v only? How do I get it to work??  

    • Curtis

      Smith731, As I’m unfamiliar with electra flush toilets I did a quick bit of research.  They are a self contained unit that recirculates the water held within.  Not your standard RV installation with a black water tank.  I would guess they need electricity (12v) to operate.  I’d check your fuses as if there is no power to the switch I believe it is unusable.

  • Joe

    During the night, something snapped on our rv toilet and now it won’t flush.  Its covered under warranty so we can get it fixed, but how can we force it to flush and empty the bowl?  thanks for the help!

    • Curtis

      Joe, Not all jobs are pleasant.   The only way to ensure you don’t damage the blade valve is to scoop out the contents and dispose of it elsewhere.  The toilet needs to be removed to access the moving parts properly.  

  • GREGORY ZOLTON

    I HAVE AN ELECTRONIC TOILET. IT WILL FILL WITH WATER BUT IT WON;T FLUSH. I REMOVED THE TOILET FROM THE BASE AND IT IS ALL PUMP AND WIRES AND BLACK RUBBER TUBING BEHIND. ANY IDEAS???

    • Curtis

      Gregory, I’m unfamiliar with electronic toilets.  If you post the make and model numbers maybe I can find some information on the internet that can provide some ideas.

  • GREGORY ZOLTON

    CURTIS, IT IS A TECMA SILENT FLUSH. IT OPERATES WITH A MACERATOR PUMP. CAN YOU HELP. THE TOILET FILLS BUT WON’T EM[PTY. THE OTHER TOILET WORKS FINE WITH A HARSH SUCTION SOUND WHEN FLUSHING BUT THIS ONE HAS NO SUCH NOISE AND WON’T EMPTY. GMZ

    • Curtis

      Gregory, This link:   http://tiny.cc/a7hi6   will take you to the Thetford webpage for the Tecma Silence Flush.  From the parts breakdown it looks like there are a number of control circuit boards and sensors, any of which might be the problem.  I would start with making sure you have power to the switch that empties the toilet.  Check fuses in your 12v panel first then make sure power is actually getting to the toilet.  Beyond that a dealer may have to track down what has failed for  you.  The website also has a link to their dealer network.  Good luck.

  • Curtis

    Bob, Yes you have to remove the toilet as access is from the back.  Parts are readily  available so very likely it’s repairable.

  • Elmer

    Hi Curtis, I have a leaky toilet in my 1984 Winnebago, I have replace the mechanism and it still leak from the side when we flush, what could be the problem, I hate to buy a new one after spending over a 100.00 buck for the mechanism, help please, Elmer

    • Curtis

      Elmer, The best I can suggest is maybe there is a seal out of place or a fitting leaking.  Sadly this is a prime example of why it’s unwise to invest big dollars into rebuilding an old toilet when new replacement toilets are available with a warranty for just a few dollars more.

  • Don

    Curtis, Do you have to remove the toilet to replace the blade seal in an Aqua-Magic Style II toilet?

    • Curtis

      Don, Though I haven’t replaced one in that particular toilet I feel confident that almost every repair to an RV toilet requires you to remove it from the RV.  Working on a bench will make it easier to make sure you don’t damage and seal surfaces or parts.

  • Dick

    Curtis,

    I’m delighted to find your site.  My Aquamagic IV no longer sends a swirl of water from the nozzle around to sweep the bowl contents down.  The bubbler below the nozzle seems to emit a whimpy flow as well. I have good pressure at other faucets.  I have the toilet out, but can’t separate the bowl from the pedestal/shroud although I think I’ve removed all the screws.  It seems glued or snapped together.  Does the sealant glue the two parts together?  Should I be thinking water valve or obstruction in the line to the toilet?  It looks like you had a similar question at the bottom of page 10 (I searched through all of them), but I didn’t find your answer.

    Dick

    • Curtis

      Dick, Here’s a link to the parts breakdown for your toilet.  http://tiny.cc/j0kx4    I hope it can help you determine where things come apart.  I don’t know if it is snapped or glued at the point  you’re asking about.  I think  you’re on the right track with both the water valve or obstruction as being the cause of your problem.  Also the water valve may not be opening all the way.  

      • Dick

        Curtis,  Thanks for the reply.  Thinking about what I’d read on your site, I tested the water flow before the toilet – good.  I then examined where water entered the valve, finding a flake of what looks like rust wedged in there, and which I imagine has been reducing flow to the valve.  Tweezers got it out; now we’ll see.

  • R.J. O’Neill

    Curtis, how do I remove a Monogram Industries Classic RV Toilet to replace the gate valve (plate) black gasket? I have no idea what model it is? It just says ‘Classic’ on the top/back of it!
    Thanks,
    RJ

    • Curtis

      RJ O’Neill,  My experience it pretty much limited to Thetford products but I did find a parts breakdown for a Monogram Ind. Toilet.  http://tiny.cc/b6dxv  I don’t know how helpful it will be for you but it shows the mounting being either one screw from underneath in the front or 2 screws, one on each side.  Looking at the diagram the screws come in from the bottom which doesn’t look very do it yourself friendly.  Good luck.

  • Anonymous

    curtis,how do you change the flange on a rv toliet.I bought a new stool and the bolts are on the side and the old one was in front and back.

  • Curtis

    Shurefire432, Here is one possibility, the flange is a screw on piece like this one:  http://tiny.cc/7zsa6    There’s no guarantee that’s how yours is though.  It might be a fitting that is cemented in place.  If it is you may have to replace it which will take more effort.

  • Adrian

    i cant manage to take off my toilet off of my Winnebago Rv
    i dont see any screws on the side that hold the toilet down

    • Curtis

      Adrian, Some have the bolts front and back rather than on the side.  Some have the bolts covered with a small removable plastic cover.  Some have the bolts inside the plastic housing.  Hard to say  which is the way yours is attached.

  • Tlco_1

    Glad i found your site it is loaded with lots of information, I just bought my first (used) rv and trusted a “friend” that had more experience with rv;s then me. Any way he missed  a few things and now I need to replace the pedal on the bottom of the toilet. I bought a 2000 Amerasian Star, your instructions look simply enough can I just replace the pedal or do I have to replace the whole thing?

    • Curtis

      Tico-1, It’s all a matter of how expensive the repair parts are.  Keep this in mind as you tackle the project and also closely watch the overall condition of other components as you disassemble the toilet.  If everything looks to be in good condition, and the dollars make sense, then repairing it is the way to go.  Check on the cost of a new toilet at the same time before you spring for the parts on the old one.  Remember new toilets come with a guarantee, that’s always a plus.

  • Lerichardson1

    I have a SL Aqua Magic its seems to leak only with the water pump on, not hooked to city water.  What could be my problem.  Thanks for your help

  • Curtis

    Lerichardson1, Your toilet is only going to leak when the pump switch is on because that is the only time there is water pressure available to make it leak.  The leak could be from numerous reasons, most likely a cracked water fitting, damaged water valve, or even a split water line.  Time to remove the toilet and bench test it.

  • Curtis

    Lerichardson1, Rereading your question, do you mean it leaks when you are running off the 12v water pump but doesn’t leak when hooked to city water?  I would find that unlikely because by the time water gets to the toilet there are no connections that would be only made to on board water source and not the city water source.  The only difference between the two would  be slightly different water pressure, not likely to bring a leak to light.  Basically you have a water leak that will require the toilet to be removed and benched tested to confirm what’s going on.

    • Lerichardson1

      you are correct it does leak either way.  Would it be wise to replace entire toilet, or repair toilet.  It  is an Aqua magic IV

  • Curtis

    Lerichardson1, Parts are available, See link:  http://tiny.cc/q6qg9  The key in my mind is “What’s leaking”.  It’s a question of your mechanical ability.  If you feel comfortable removing the toilet and checking out exactly what is leaking, you can probably get by a lot cheaper with repairing the toilet yourself.  If you take it to a dealer and have their tech investigate the problem consider they will charge you about $100 an hour for labor.  It wouldn’t take long to bypass the cost of a new toilet in their hands.  There are only 2 bolts holding the toilet in place and 1 water line hookup.  Installing a new toilet is pretty straightforward.

  • Lerichardson1

    I found the leak in the water valve.  How do I change out the valve.  Thanks for your help.

    • Curtis

      Lerichardson1, Refer to the link in my last response, and order the water valve replacement package.  Make sure you have matched up to what your valve looks like.  It appears to be threaded on one end.  If so, unscrew it.  Only use Teflon tape as a sealer for the treads and be careful not to over tighten.  It’s plastic and will break.  Not much else I can tell you  because I’ve never had one apart.  Mostly take your time and I’m sure you’ll figure it out. 

  • Curtis

    Bertacgann, It would mean a complete re-plumbing job.  Household toilets seal with a wax ring that gets sandwiched between the toilet and the flange.  RV toilets have an o-ring that fits in a grove.  It would be quite a project to make it work.  If you’re looking for china rather than plastic there are RV toilets that are china with the feel of a standard household toilet. 

  • Jkhinch25

    Hi, I’m finding a lot of repair info for rv toilets with blades – but I am losing water through a flapper. Would you happen to have any tips for leaky flappers?

  • Curtis

    Jkhinch25, Toilets with flappers are usually found in homes, not RV’s.  Regardless, usually the problem isn’t the flapper but the water control valve is out of adjustment and doesn’t shut the flow of water off before the water level reaches the top of the standpipe in the tank.  When water runs over the top of the standpipe it trickles down into the bowl and you see continual water movement as the excess water runs  into the sewer line.  On the rare occasion where the flapper is leaking (causing the toilet to run), it is possibly hung up on the chain that lifts it or has hardened to the point it no longer seals.  If it won’t seal it needs to be replaced.

  • Bill Sostrich

    We have the Style II Thetford.  I just “dewinterized” it (only blew out the lines – no pink stuff).  Now (and this happened last year as well).  Now the water is shooting out of one side of the nozzle in the back.  Is there a way to take that cover off of the outlet?  What is causing this?  Last yr I stuck a toothpick up in there and it seemed to free up whatever was plugging it.

    • Bill Sostrich

      Just kept working with the toothpick thingy and it finally is working again.  Anyone else have problems like this.  We use filters before any water coming into RV. 

    • Curtis

      Bill, Could be a piece of dirt or plastic has found its way into your water line.  The toothpick may have dislodged it last year, but better to take it apart and clean it this time around.

    Curtis,

    I have a 2003 Keystone Challenger and need toilet parts. How can I figure out what kind of toilet I have? Pamela

    • Curtis

      Pamela, Somewhere on the toilet the make and model should be labeled.  I believe Thetford toilets have the information on the inside of the lid.  If you can find the make, Thetford being the most popular, you can go to their website   
      http://www.thetford.com/  and identify your toilet.

  • JaJe

    Curtis,
    I dont know what kind of trailer I have, but I get a nasty skunky smell when I flush the toilet.  Every once in a while it starts smelling without us even opening the flap.  We have it connected to a septic tank, but sometimes the smell is so bad I have to go outside.  What do you think it is?

    • Curtis

      JaJe, Gee, that’s an easy odor to trace down, it’s Human Waste.  When you flush the toilet you open the gate valve and the odor from your black tank rushes back at you.  I’d check the vent on the roof to start.  If the gases are trapped in the tank they can actually build up pressure which makes the matter worse when you flush.  Next be sure you keep plenty of water in the black tank.  If you’re allowing the water to drain off into the sewer the solids will build up in the tank creating more odor but also eventually it will block off the drain and then you’ll have a mess.  If you suspect a build up I’d flush the tank with a designated “dirty” garden hose through the toilet.  It will probably take numerous flushes to get rid of a buildup. 

  • 1788lhubbard

    We have a 2007 Cougar Keyston 2871BK and not getting the water to flush, what should I look for?
    It worked will we were turkey hunting for a week but get home and now not working.
    Thanks
    Lee

  • Curtis

    1788hubbard, My first thought would be linkage to the water control valve.  That’s assuming the rest of the water system in the RV is working properly.  Do the controls feel like they are working properly (either the foot pedal or hand control depending on the model)?  

  • Tom

    There is barely any water going to the toilet when we flush.  It is an Aqua-Magic V

    • Curtis

      Tom, You ;may have a linkage problem going to the water control valve.  Here’s a link to a parts breakdown that may shed some light on how things are put together. http://tiny.cc/8sjmew

  • Geoff

    I have a 1985 Coachman Leprechaun on a Ford E350. I have a couple of problums with the toilet. When step on the flush pedal the toilet rocks foward also the carpet gets wet even when you hold it in place.

    • Curtis

      Geoff, It sounds like either the floor is rotten or the mounting bolts for the toilet are loose or broken.  Either way if the toilet is rocking back and forth the o-ring seal is likely leaking when you flush the toilet.  

  • Charlie9702

    My rv toilet just started having a vacuum when flushed it will blow the water up when flushed almost like there is a vacuum created somewhere between the toilet and holding tank. What can cause this?

  • Curtis

    Charlie9702, If it’s blowing the water up at you it is building pressure.  A vacuum which would cause the toilet to empty unusually fast downward.  Regardless, the problem is likely in the roof vent which should be not only directing the smell out the roof but allow air to come and go as needed for the waste tanks.  Decomposing sewage will create gases and also the mid-day heat will build pressure. If the roof vent is plugged due to debri or even a small critter getting into it, the pressure will build up in the tank.  There may be multiple roof vents as all three waste tanks should be vented.

  • Steve

    I have a 1974 red dale and with the factory toilet I presume. The deal that slides open when you step on the pedal is stuck open now. Need to remove toilet to rebuild I’m sure. But have no  idea how to remove. Tried to seperate the top from bottom at seam. No luck there. HELP Thanx Steve

    • Curtis

      Steve, There should be two bolts holding it to the floor located under plastic covers on each side. On some models the bolts are front and back instead.  

  • Trimmy72

    I have a 1983 Coachman I recently purchased in great condition, I hooked up my well water to it to flush the system out and ran the toilet. After flushing,  the toilet started leaking at the top. It’s not coming from the fitting’s, it’s in the same area but drips from an open hole more toward the back (part of the seat, no cracks). This part of the toilet, is housing the rinse and flush levers. I would like to remove this part to take a closer look. This part of the toilet looks like it could come apart but I’m not sure if it snaps together or is welded (plastic) in place. Any Idea’s what I might be dealing with? By the way it’s fresh water that’s leaking.Thanks Chris

    • Curtis

      Trimmy72, You will need to remove the toilet to access the mechanics of it from the back.  Likely the water control valve, or a fitting related to it is the culprit.

  • Sheilalynne1955

    I have a 2006 Hyline Park Model  had it in storage for 2 months and then moved to a new park I have tried every chemical to stop the toilet odor but to no avail .I checked for leaks  none.Is there a black or gray water vent on my roof? I really cant see it from the ground .I just cant figure out why the odor wont go away I have a pedal toilet Any suggestions appreiated Thanks Sheila 

    • Curtis

      Sheilalynne1955, Yes there is a roof vent that may or may not have a cap over it.  On RV’s designed for travel there is a plastic cover to keep debri from falling down the pipe.  I don’t know if that is the case with park models.  There is a slight possibility that by relocating to a new park you have happened upon prevailing winds that are pushing air down the vent pipe rather than venting gases out.  There is a vent cap “The Cyclone” that is designed to swivel and follow wind current to assure there is suction to draw sewer gases out the vent pipe.  This link  http://tiny.cc/tgwcfw   will give you a source if that is a possibility for your situation.

  • Tim

    Water sprays out of the back of toilet what can we do

  • Curtis

    Tim, You will have to remove the toilet, it’s held down by two bolts, to inspect and determine what’s causing the leak. If you’re up to the repairs, parts can be ordered off the internet. If not a replacement toilet can be ordered as well. Compare the cost of parts and effort involved to make the decision whether to repair or replace. Replacement is fairly easy, repairing sometimes not so much.

    Hi Curtis,
    I have a Thetford Aqua-Magic Style Plus toilet, model 34424. The problem is that when I want to add water, no matter how little i press on the pedal, the blade/ball will come open. This occurs even if I were to press the pedal as little as 1/16″. What needs to be repaired to I can add water without flush? Thanks! ! ! Don H.

    • Curtis

      Don, Sorry, I haven’t had any experience with these newer 12v toilets. I couldn’t even find any parts information for that particular model number.

    I have a 1985 winni and i am trying to fix a leak on the toilet but am un able to find said bolts that hold it down??

    • Curtis

      Stoney, It varies by model but usually they are either on each side probably under a small plastic cover or front and rear accessible from the back.

      • stoney

        Thank you so much. They were in front and back. I was able to fix the toilet without problems. Thank you once again for your help.

    Very well described. In fact it is very important the little is there at the bottom or else it gets odd. One of the reasons for the disappearing of that water on occasions is the Mal functioning of the plumbing system.

  • Ola Novak

    I have a Thetford Electra-Magic Model 80 Recirculating Toilet in my 2000 TrailManor 2720 SL Travel Trailer. I can’t evacuate 100% consistently. On a recent 5 week trip, I pulled the T-handle (termination valve) on bottom of toilet every few days for 2 weeks when we were leaving campsites and heard a whoosh sound which seemed to indicate the contents had gone down into the toilet’s internal holding tank. But the gauge did not go down to E but stayed at or slightly below the F. After 2 weeks, after pulling the T-handle, there was a very loud whoosh sound, and the gauge went down to E. Great! In the next week, I recharged, then after pulling the T-handle twice on different days, this small whoosh happened each time, no movement in the gauge, then the third time a loud whoosh, and the gauge went down to E. Great! The following week, I recharged. At our last campsite, I pulled the T-Handle, small whoosh, no movement in the gauge. Because I wanted to totally evacuate, I probably pulled the T-handle another 20 times. No whoosh, no movement in the gauge. Back home now, I believe the toilet is still full of water, since gauge is on F. We now have noticed possible leaking underneath the travel trailer where the toilet sits. FYI, we are not heavy users of the toilet, only at night. I don’t want to have the RV sitting in storage with a full tank of water/chemicals. How to evacuate? Any ideas? THANKS!

    • Curtis

      Ola, Sorry but I’ve had zero experience with recirculating toilets. Not much I could suggest for you.

  • mickey

    I have a 1988 Citation 5th wheel in great shape,,my question is how to remove the toilet as it is leaking bad,help?

    • Curtis

      Mickey, Two bolts, either one on each side possibly under a small plastic access plate, or one front and back accessible from the rear of the toilet.

  • Steven Range

    I have a Raptor fifth wheel that the black tank has started leaking if the tank approaches the full mark. From underneath it looks as if it is leaking where the toilet attaches. I usually try to wait until it is almost full to dump it to make it easier to flush it all. However, sometimes I miss it and get a sewage leak out of the top of the tank? How do I go about finding the leak and repairing it. It has a domentic Sea/land bowel on it.

    • Curtis

      Steven Range, It sounds like the fitting from the toilet has come loose or cracked where it enters the black tank. I’d start by removing the toilet and seeing if you can approach the problem from that end as the only other alternative is to remove the tank from the bottom.

  • Paul Lundell

    I have a 2006 Thor Tahor Transport 3950 GS, The black water tank seems to have a pee trap on it. It continually plugs. We have a 6ft piece of pex pipe that we just to push it through and all is well again for awhile? Not sure if we just need to use twice as much water to help keep this flowing or if there is something else wrong. Any info would be greatly appreciated.

    • Curtis

      Paul, I would bet on not enough water. That’s the most common problem with toilets. It wouldn’t hurt to send a couple gallons of water into the tank after draining it so there is something to break up the solids right away.

  • nikki

    Our 5th wheel toilet is hooked to a septic tank…it works fine..but whenever we flush it it smells up the whole rv with a terrible sulfur smell..not sure what we should do

    • Curtis

      Nikki, If you are leaving the black water tank drain valve open all the time so the toilet goes right into a septic tank you have two problems. First the sewer gases from the septic tank can come right back up through the toilet and cause the odor you smell. Secondly I guarantee you will have blockage problems at some point because RV toilet tanks were designed to hold the waste in the tank and will only flush the tank clean of solids if the valve is left closed until the tank is full. The rapid draining of a full tank when you open the valve is required to flush the solids out of the tank. The more water you use in an RV toilet the better. It helps breakdown the solids.

  • denny

    My toilet in our Avion overflows instead of stopping like its suppose to. It seems as though the small pedal is stuck or something like that.

    • Curtis

      denny, I think you’re right. The water should stop as soon as you take your foot off the pedal.

  • Cindy Thomas @tire covers

    I’ve encountered issues with my RV toilet and had no clue how to fix them, so this post is a life saver. Thanks!

  • Liza Pilon

    There is something wrong with the blade seals if the toilet
    fails to hold water. There might be some scrap trapped in it, so you must
    check. Well, if you noticed that the seal has become moldy, then, you might
    actually need to replace it because a good blade seal must be firm and plump.

    My toilet motor is totally broken after one of my childern keep disposing flushable wipes into the toilet. I flushed toilet few tines and removed all the wipes that came out from the pipes. However, toilet motor is completely stopped. How can I fix it and how much will it cost to replace or fix the motor? ? thank you!

    Curtis,

    I have Aqua-Magic style plus RV Toilet. When I hit the pedal water comes out but Waste ball doesn’t rotate open to flush. I have it taken apart. I don’t see anything broken…..There is the cable that opens the water valve I believe. It looks fine. What would be the reason the waste ball doesn’t’ open? How does that actually work?

    • Curtis

      Raul, Here’s a link to the parts breakdown http://tiny.cc/lp1ojw It looks pretty straight forward, ball – cable – pedal. Is the cable casing moving somehow so that the pedal movement isn’t being transferred to the ball? That’s about the only thing I can think of if nothing is broken and the cable is good.

  • SoggyRV22RK

    I have a 1996 Electra 22RK and have a water leak in the pipes that is flooding the undercarriage liner. I replaced the water heater and there are no leaks around that, so I’ve trouble shooted the problem to the lines. The problem is I can’t see any lines underneath the RV and there are no openings to trace the lines. Do I have to take the linings off to reach the lines or is there an easier option?

    • Curtis

      SoggyRV22RF, Probably yes, unless you can run new lines and disconnect the leaking ones from the water system. Sometimes it’s easier to just run new lines if you’re sure the old sections are leaking. You don’t necessarily have to follow the same routing if you can find a more accessible route.

  • Tom

    Hi Curtis,
    I’m new to RVing and I was wondering if there is a converstion kit available to install a foot pedal instead of using hands to flush. And if there is, would you use the converstion or would you just replace the toilet all together? I appreciate the help!
    Tom

    • Curtis

      Tom, I’ve never seen a conversion kit to switch from hand controls to foot pedal but the good news is the Thetford Aqua Magic V can be purchased either way. http://tiny.cc/pfx4jw

  • Jessica

    We are experiencing the #2 problem, where now the water is constantly running and filling the toilet, so we currently have to have the water in the RV off so that the bowl doesnt over flow. or rig the handle to remain open so the water runs down into the tank while we use water and then shut it off again. What needs to be done in order to fix this problem and do I need to call around for a part?

    • Curtis

      Jessica, You will probably have to remove the toilet so you can work on it on a bench. Likely the water control valve is broken, or has become disconnected from the control. You won’t be able to determine what parts you need until it’s torn down. Do be aware that if it’s an older toilet it may be more cost effective to just buy a new one. If you need to take it to an RV dealer to do the work their labor charges will be around $100 an hour. It won’t take long to run up a tab well over the cost of a new toilet which is a simpler do-it-yourself installation.

  • Raul Martinez

    Hey Curtis,

    I have the Aqua Magic Plus toilet. I find a small puddle of clean water in front of the toilet right under the pedal. There’s always water in the toilet. Can you tell me where you think it might be leaking from?

    • Curtis

      Raul Martinez, If I was to guess the most likely candidate would be the water valve inside the toilet. The water could be running down the inside and weeping out onto the floor by the pedal. It’s possible water is being sprayed over the lip when you flush. Check for that before you remove the toilet for bench testing.

  • justin

    I have a kountry air 5th wheel..not even sure of the years..late 70s I think..but the toilet just started running and won’t stop..like the pedal is all the way down..the toilet says is aqua magic the model go and gh..

    • Curtis

      justin, It may be a number of things any of which can be determined by removing the toilet from the RV and inspecting from the back. Linkage, a broken spring, a bad water valve, it could be any of those.

  • Curtis

    Bob Shaw, Pretty much any repair means removing the toilet from the RV.

  • Ray E

    Hello Curtis and thanks for your forum and sharing your expereince.

    2006 Itasca Ellipse with a Thetford Magic Style Plus

    Toliet flushes and operates normally except when the foot pedal is depressed to add water to the bowl.

    Flush the tank only, remove foot from pedal — adequate water flow through out the coach

    Flush the tank & depress footpedal to add a little water to the bowl- remove foot from foot pedal — inadequate/anemic water flow though the coach — to remedy we have to go back and flush only to get adequate water flow through out the coach.

    We are second owners and just getting aqainted with the coach, this has been going on all along, it wasn’t as severe in the beginning (thought it was from demand at RV park). It was just recently that it developed to the point that other taps were essentially no flow or just dripping and some how we made the connection to the cause and effective of the toliet flush and refill.

    Thoughts? I need the RV for another month before I can shut down and service. But at looking at the parts diagrham and your comments about rebuild vs replace I am leaning towards replace.

    But should I be looking at the vacuum breaker or other as the cause of our problem?

    Wishing you success in all things

    • Curtis

      Ray E, That’s an interesting problem. At first I was thinking maybe the water valve isn’t shutting off all the way when you depress to add water to the bowl. Only problem is then the bowl would fill to the point of over flowing. At this point I’m not even sure the problem is in the toilet so I wouldn’t be too quick to replace it. This may sound crazy but I question the check valve that is built into your city water port. Maybe a momentary drop in pressure when you partially depress the pedal is enough to unseat the check valve which would allow water to run from the city water port into the fresh water tank. When the tank gets full the excess just runs out the vent pipe to the ground. You may not even know it’s happening. By doing a full flush the valve is seeing a bigger pressure drop and may be seating properly. That’s the only connection between the toilet and the rest of the water system.that I can think of. If that’s what’s happening a new city water connection, which includes the check valve, is a whole lot cheaper than a new toilet.

  • Karen Vaughan

    Curtis – can you help us diagnose the problem/part with our RV toilet? When depressing the pedal to add water to the bowl, the dump valve/bowl gate opens before the bowl fills with water, thus not allowing any water to stand in the bowl. Is there a particular part we should look to be in need of repair? Will we likely have to remove the toilet in order to repair it? Thanks for your assistance!

    • Curtis

      Karen, Usually you depress the pedal only a little way to get the water running. All the way opens the valve to dump the waste. If no water is coming in you may have a linkage problem at the water valve, or the water valve itself may be the problem. Either way you will have to remove the toilet to disassemble it to determine what is going on. Diagrams for Thetford toilets are available here: http://www.thetford.com/HOME/tabid/71/Default.aspx

  • sherman

    curtis my toilet is holding water between toilet an tank the tank is empty but water will not drain any sugestions please

    • Curtis

      Sherman, It sounds like your black tank is plugged up with solid waste. Stick a garden hose up the drain and flush it out for a while. Then when you have everything working again keep the drain valve closed until the tank is full otherwise the water drains off and the solids stick in the tank.

  • Normand

    Right pedal stays down and free and wire seems free too on Thetford Aqua Magic IV. What can I do?

    • Curtis

      Normand, I recommend removing the toilet so you can work on it on a bench. You need access from the back of the toilet to see what’s going on. It sounds like a linkage problem to me or a damaged valve.

  • Brooke

    My Aqua Magic IV hand flush toilet stopped flushing smoothly. I took the toilet off and apart and holy crap, the blade seal is completely missing. There is only one place for it could have went……any ideas what, if anything, should be done about a blade seal in a black tank???

    • Curtis

      Brooke, I wouldn’t loose any sleep at this point. Most tanks are sloped toward the drain. At some point the seal may end up across the drain opening and start collecting toilet paper. If at some point in the future you notice the flow of waste coming out when you drain the tank slowing down, you know where your seal ended up. Take a wire coat hanger and bend a hook on one end of the wire then open the drain valve with the tank empty and hopefully you can hook onto the seal and pull it out. Best to have a bucket handy to catch whatever comes out with it.

      • Brooke

        Thanks so much for your advice! I replaced the blade seal without issue and so far haven’t had a problem with the old one moving over the drain. I appreciate your help!

  • Franklin k Laune

    HI i need help Ok out camper is stationary so we live in it every day! Well one day the water froz due to a outage! Well one day my fiance went to use the bathroom and the toilet is filled with ice! Waht can we do to melt the ice clogging it!

    • Curtis

      Nicole and Martin, Pour in hot water, turn up the thermostat. If that doesn’t work, wait for spring.

  • Guest

    We have a Thedford “area delux” push button flusher. When the toilet is flushed, it does not shut off unless we reach behind the toilet and grab the manual flush knob and stop it’s spin. What needs repair?

    • Curtis

      Sharon, I guess I’m old school… I have no experience with that model of Thedford toilet. The best I can offer is a link to the parts breakdown diagram: http://tiny.cc/3xvxrw
      It’s not much but I hope it helps.

  • JohnDeere1953

    Dear Curtis, I am a widow and need some advice. My Thetford Aqua-Magic IV Hand Flush toilet bowl does not keep it’s water. After flushing I put water in the bowl and it slowly leaks out. I tried to get a repair kit with that seal in it, but was told by the RV store that it was an obsolete toilet not installed in any RV since 1999 and I will have to buy a whole new toilet. Is this so or are they trying to take advantage of me? My Jayco fifth wheel is a 2003 model. Thank you.

    • Curtis

      JohnDeere 1953, Here’s a link to the Aqua Magic IV parts breakdown http://tiny.cc/nk3mtw it will show the part number for the blade seal to be 33027. This next link to Amazon.com will take you to the page for that item http://tiny.cc/8o3mtw As you can see the price is $3.79 and is currently available. In defense of the RV store if you are going to have a dealer replace the seal, which will mean removing and disassembling the toilet, likely the labor charge, which will be around $100 per hour, will make it economically more feasible to just buy a new toilet complete with warranty. Here’s where it pays to be a DIY person.

      • JohnDeere1953

        Dear Curtis, Thank you so much for the links. No, I did not plan to have a dealer do the repair. I am quite mechanical and have good friends here at the military campground who will help me. $3.79 (plus the batch of cookies I will make for my friends) is a lot nicer than $170 for a new toilet that might not even fit the same bolt holes in the floor. Thanks again.

  • Craig

    Hi Curtis, I’m hoping you may be able to provide a reason/solution to an overflow issues that has occurred on rare occasions from our RV Thetford aqua-magic style 2 toilet. Thankfully this is not a regular issue, but on the odd couple of occasions the water flow into the bowl fails to fully cut-off resulting in the bowl filling and then slowly trickling over the top and across the neighboring floor of the RV. Before I attempt to dismantle the unit in search of the cause, could you direct me to a possible cause and best means to remedy. My wife and I now commonly pull up on the foot flush arm to ensure shut-off. This is now harder to police with young children.
    Thanks Craig.

    • Curtis

      Craig, You’re on the right track as the two most common problems would be linkage or water control valve related. About the only thing you can do without removing the toilet is to check that debri is causing the foot pedal from returning all the way up when released. Beyond that you will have to get more aggressive in troubleshooting which will pretty much require you to remove the toilet for some level of disassembly.

      • Craig

        Thanks Curtis. With regards to the foot pedal arm, is there a spring system that over time loses its tension and if so, can this be easily replaced? The other area I thought about is the shut-off valve. Is there anything complicated here in terms of mechanisms and could this overtime be affected by ware and tear and need replacement? Once again, are these easy repair/inspection items or do I need to fully remove the toilet system from the van.
        Thanks Craig.

        • Curtis

          Craig, This link will take you to Thetford’s information on your toilet: http://tiny.cc/9073tw The reason most all repairs require removing the toilet is access to the mechanical parts is from the rear…Where you can’t reach when it’s mounted in the RV. To be honest I’ve never worked on this particular toilet but with toilets the common thread is a water control valve and linkage is most often the cause of water related problems. The Thetford webpage gives you access to the parts breakdown, downloadable manual, and some videos that may assist you. Hopefully it will provide enough guidance that you will find the problem.

  • Mac

    1971 avion voyager, I have a slight drip in the area around where the water connect to the toilet.(aqua magic galaxy 40) can I repair it? And if so, where are the screws to remove the toilet ? Thanks for your help. Mac;

    • Curtis

      Mac, Here’s a link to the parts breakdown: http://tiny.cc/ec0guw In most toilets the two bolts that hold the toilet down are accessible by removing a small plastic cap on the sides, or they are accessed from the rear of the toilet. Also on some models the two bolts are front and back, not on each side. The breakdown picture doesn’t really tell which way your’s is mounted.

  • ryan

    I have a 1971 fan trailer with a green aqua magic toilet the spring that connects to foot pedal came loff and unsure of how to repair it any ideas

    • Curtis

      Ryan, Best I can suggest is to remove the toilet from the RV so you can attack the problem from the back side. Most all repairs are done from the rear of the toilet. Once you have it on the bench you will probably see where the spring attaches.

  • mike kebschull

    I have a 74 winnabego brave. The toilet has a samll leak in the back unless all the pressure is off the line. how does this toilet come apart?

    • Curtis

      Mike, You need to remove the toilet from the RV. It’s attached with two bolts either on each side under a small plastic cover or front and back accessible from the rear of the toilet. With the model name you can find a parts breakdown here: http://tiny.cc/lcyqxw

  • David West

    I have a aqua iv hand flush toilet,water leaks between top and bottom of toilet under rim, I have not tried to tighten screws yet,is that a good place to start.

    • Curtis

      David, Here’s a parts breakdown of your toilet: http://tiny.cc/2d3ayw Looking at the picture the inner part of the toilet is a one piece unit (probably two halves glued together). You’ll note there is no part number listed for it so I assume if it is indeed cracked and leaking you’re looking at replacing the whole toilet. It’s more likely you have a cracked fitting or water valve which are replaceable. To confirm what’s going on you need to remove the toilet from the RV as repairs are accessed from the back.

  • Ann Larrabee

    My husband just installed a Thetford Electra Magic RV toilet. When the flush button is pushed should the pump run 10 sec (as with my old toilet) or only as long as the button is pushed? Is this a function of polarity? We want to make sure the electricity is correctly hooked up.

    • Curtis

      Ann Larrabee, I’m not familiar with that particular toilet so I can’t answer on the length of time the pump runs. I feel certain though that as far as polarity goes, red is positive, black is negative and backwards will probably make smoke.

  • Daniel Wayne Tomes

    Curtis, I have a aqua magic Starlite toilet. The toilet is leaking around the bottom whenever we have water sitting above the gate, even with no water hookup and pouring water in it starts leaking around the left side. Could that possibly be the gate seal or the toilet seal itself? Thanks for your time

    92 Fleetwood pace arrow

    • Curtis

      Daniel, It could be, but I wonder. I think if the blade seal is leaking it would go down the pipe to the black tank. If the toilet seal was leaking it would only do so when the toilet is being flushed. What are the odds that both seals would be bad? Best to remove the toilet and inspect the whole blade mechanism. You might have a crack somewhere. Here’s the parts breakdown, it might be of some help. http://tiny.cc/keg6yw

  • Angie Wynn Strickland

    Hi Curtis, We have a 96 Coachman with a leaking water line to the toilet, How do I remove that paneling that they have around the sink and behind the toilet to get to the line with busting it?

    • Curtis

      Angie, Some manufacturers are good about using screws in panels that hide plumbing lines. Some, not so much. Worst case scenario you may have to damage the paneling . Do it neatly and you can make a replacement piece or cover to make the project easier next time.

  • W Steele

    Curtis : I have a 91 hitchhiker with a thedford toilet. I have had a problem that Ihope you can help me with. It does not hold water after I flush very long and just before i was done using it for the season the water valve I think got stuck and was running all the time. I caped off water line and winterised it. I got a good used toilet on ebay but it did not have a water valve on it, but by the time I got around to changeing it it was to late to return it. I went to get a new water valve and was told that it mite leak, and then they tryed to sell me a new toilet and yes this this was a rv repair place. I was writeing to ask you do you think I can repair the first toilet or get a new water valve for the one I got on ebay. Any help would be great. What do you suggest I do. Thanks for your time. Wally

    • Curtis

      Wally, If the Ebay toilet didn’t have the water valve you hardly got a good deal. When you buy sight unseen you get what you get. Parts are available through thetford http://www.thetford.com/ but you will have to remove the toilet from the RV and disassemble it to find out what you need. RV dealers will recommend replacing the toilet with new because their labor charge is around $100 per hour. It’s not worth your money to have them spend half a day repairing an old toilet when they can install a new one faster and cheaper. Plus you get a warranty with a new one.

      • W Steele

        Curtis : Thanks for replying. If I get a new water valve for ebay toilet is thier any thing special I need to do when I put it in toilet like sealer or just put in dry. I know everthing else works. Thanks again for tour help. Wally

        • Curtis

          Wally, Depends on the type of fittings. If they’re pipe thread, a little teflon tape would do. Be careful not to over tighten, you can easily split a plastic fitting. If you have compression style fittings, no sealer is needed.

    We have a thedford aqua magic 4 toilet in our motorhome The problem is that the water coming into the bowl comes in very very slowly after flushing. So to save time holding the rinse handle open to have enough water in the bowl we have poured a cupful or so of water from the sink tap into the bowl. Could you explain how to fix this problem. Thanks
    A Sask Camper

    • Curtis

      A Sask Camper, You have either a water valve problem, a linkage problem, or a partially plugged water line to the toilet. Best bet is to take the toilet out of the motorhome so you can investigate further on the work bench.

      • A Sask Camper

        Thank you for the help and prompt reply, Curtis… for now we may continue to add the bit of water from the sink tap till we have the extra time for a proper repair.

  • Carolinda

    Curtis, we’re replacing a 1973 Argosy’s Aqua Magic SL which both leaks and has unattractively discolored. What new models matches the attachment configuration? Thanks!

    • Curtis

      Carolinda, For the most part toilet attachment and plumbing is standard within the industry. Two bolts holding it down and a water source plumbed into it. I don’t think you would have much issue hooking up whatever model you choose.

      • Carolinda

        Thanks, Curtis, I’ll order today.

      • Carolinda

        Curtis, you wouldn’t know about replacing vent hoods, would you? My 1973 Argosy’s is ducted, not a hood type, and mounted up through the bottom of the upper cabinet, with the operating unit up in the upper cabinet. No spec or model label. With your experience, would replacing this original with a hood type be problematic (probably) and in what ways? Thanks.

        • Curtis

          Carolinda, Sorry, 1973’s a long ways back. I don’t know what you have without seeing it. You can do a search on Amazon.com for “RV range hood” and all sorts of items come up. You’re in a better spot than I to figure out what will work for you.

  • RBain

    I just purchased a 1984 Chevy Winnebago and am in the process of refurbishing it. The toilet is definitely a sight for sore eyes…Since the park that we will be staying at has facilities, I want to remove the toilet all together. I have located the bolts, (1 under the foot pedal and 1 deep inside the small access hole under the seat of the toilet). My question is, is there a shut off valve for the water supply line to the toilet, and where can I find it? Or, do I just need to CAP the existing water supply line to the toilet? Thank You in advance for your help and advise!

  • RBain

    Regarding my 1984 Chevy Winnebago: I just removed the range/oven and put in a newer, larger model. The fitting on the new unit is a little smaller than the fitting on the LP supply line. What is your advise for handling this type of situation? Thank You in advance for your help and advise!

    • Curtis

      RBain, go to your nearest home center. Show them what you need and likely they will have something that will work. It’s all standard stuff in RV’s

  • JAY

    Curtis, I have a Thetford Aqua Magic 4 and have been plagued with Black Water odor issues since we bought this RV last year. I have taken the toilet out and cleaned it from top to bottom and replaced the foam ring at the base. I flipped the toilet over and filled it with a bleach water solution to disinfect the inside. That’s when I noticed a major issue. The water all leaked out from a seam on the top (the seat) on the toilet…meaning that this toilet isn’t completely sealed! The bigger issue is that there is a 1.5-2 inch gap between the toilet blade and the foam ring (toilet base). There is no hose, no pipe…nothing. It basically seams that the waste just drops from the blade and falls into this open pipe to the black water tank like a faulty water slide! I can stick my fingers into the gap so it’s pretty wide. My questions: Is this a some kind of design flaw? Am I missing something? Is the toilet supposed to be sealed water/air tight? What can I do to stop the black tank fumes from coming through that seam? Is there an “old trusty” of toilets that I can get to never have this problem again?
    Thank you for your time, Sir! I appreciate any help you can give.

    • Curtis

      Jay, Something is sounding not right but from here there isn’t much I can do for you.

    • Curtis

      Johnhorse, Granted that is getting pretty old, but the standard configuration has two bolts either front and back or on either side. They may be located on the inside of the toilet case and I’m sure they won’t be easy to get at.

      • johnhorse

        Curtis, thanks for the info.I have not found any bolts any were on the toilet base so figured it may be bolted from the bottom . If that is how it was put in I’ll just have to brake it up to take it out,bummer.
