Toilet bowl leaks down

[Roger Watts]

I have new Excel with the ceramic toilet, Thetford. The toilet bowl leaks down the water through the trap almost immediately. If you side step the fill lever, it slams shut hard enough to keep the water in for hours. How do you adjust this so I don't have to slam this. I figure this will probably break it in due time. Tried a little olive oil on the valve, didn't work.

Roger we are having the same problem with our new coach. I've tried about everything, if you come up with a fix please PM me!

Fairly common problem -- solid matter becomes trapped in the rubber seal that the dump valve slides into. There is a tool available at some RV supply stores that you can clean the seal. You could also use a Q-Tip but be careful not to drop it into the holding tank--I wear a pair of the disposable latex gloves that I use for dumping my tanks.

My toilet developed the same problem. After trying to clean out any foreign matter which did not help, I tried some Thetford Toilet Seal Lubricant which solved the problem almost immediately.

I had problems with my Thetford seal from 3 months of service. I did the cleaning of the seal and treating with Thetford sealer conditioner. All were only temporary repairs. It got so bad that the the seal started binding on the ball valve. Used various lubricants only for short term repair. Someone told me that Thetford had a "new and improved seal". Called Thetford and they declined that statement. Donna ordered me a new seal and I installed it. No problem and works great for 1.5 years! I noticed a green "teflon like" coating on the sealing surface of the new seal even though there was no new part number change. The old one had a white/clear coating. Coating had come off the surface of the old seal.
I also suggest that you not use strong, abrasive, or caustic cleaner on the toilet. It would be very hard on the seal! I use the scrubby bubbles on mine.

Now you can tell me that my comments belong in the toilet and mean it!!!

Tom,

I don't think so!

A design flaw for sure, we have the same problem. I clean it once in awhile and the problem really never goes away although temp fixes help. I sort of figured this is the design.

Hi all

A trick that has worked for us is to add additional water and then some toilet paper on the top before you put any solids in the toilet.

This increases the flushing action and also many times the solids just become wrapped in the paper and slide right into the holding tank without hitting any of the flushing mechanixm.

Just another thought.

One more solids trick (as long as you are at a hook up site) is to, oh, umm, how can I put this. . .step on the toilet flush pedal at the same time as depositing your solid material. (yeah, that sounds "clean" enough) This keeps "debris" away from the seal in the first place.

We don't do this boondocking, wastes too much water. But works great in a campground. (keeps the bowl cleaner too!)

we have a porcelin toilet in our unit and when we clean it we open the valve and clean the rubber ring with a small vegetable brush. no, it is not the same brush we use for our vegetables. our unit is 3 years old and we are not having any leak problems. we also add a little water after each flush.
