Toilet overflows

All of a sudden our Thetford Bravura (6 months old) wonít shut off when you flush it, Fellow at thetford says the toilet needs at least 40psi to work properly. Seems strange to me as we have used it for 6 months with no problem (on coach pump and on city water connections). Anyone have any suggestions?

Hi Bonnie.... your internal water pump should be producing 40-42 psi. Most CG and RV parks are in the 40-50psi range, although I have been to a few in the 30s.
Frankly, from your brief description it sounds to me like either your toiletís water valve has partially failed, or perhaps some part of the linkage from pedal to valve. Have you pulled the front panel to take a look? The problem may be obvious once you put eyes on it. Good Luck!

I've had the same problem on occasion. It seems to be a pressure issue and I've had to turn off the supply valve at the floor near the toilet to stop it. It will work ok for a week or so and then happen again. Each time I have made sure the pressure is up and let the foot lever come up sharply. I'm going to take the thing apart and see if some waterproof grease on the valve will solve it.

Thanks for the info. Will pull the front panel and check the linkage.

I had my toilet overflow caused by my water valve. Before the overflow I noticed standing water around the base of the toilet. Feeling around I felt water dripping from the water valve.

Also my ball valve never made a good seal allowing odors to creep into the coach.

My rig is a 2016. Thetford said that my toilet was to new to have such issues. They didn't offer parts but they did send a link to a video to rebuild the toilet.

So I pulled my toilet out and I replaced my ball valve seal, water valve, and the vacuum breaker. My toilet now works as it should have when it was new.
