Thetford toilet won’t stop running

[Moseh]

Was winterizing my Pinnacle 37mdqs. Stepped on the foot pedal of the toilet to run the antifreeze through.... won’t stop running. Hopefully an easy fix. Any Suggestions?

The valve on those toilet can go bad. I had to replace the valve on mine after I noticed it had filled up the bowl from a slow leak a couple of times. It's kind a crappy job to do, too, since removing the toilet from the floor is required for the valve replacement.

I does, but if I have to pull the toilet out to replace the water valve, I may as well replace the ball kit also.

I had to replace the ball kit on mine and found that it was ok but it had toilet paper rammed into a the slide keeping it from closing properly. Found a more up to date thetford Thant can have the ball changed without having to take the toilet off. Almost the same price as cost of the ball valve.
