Has anybody got maintenance and repair experience with the Scamp
I pulled the toilet out of my 16' Scamp
to better address the issue I'm having: The bowl won't hold water, which allows odors into the trailer. The ball valve doesn't close tightly against the seal, so water drips right out of the bowl into the holding tank.
The toilet is about 2 years old (trailer was new in 2014). I saw elsewhere here, that somebody suggested allowing the flush pedal to snap back, rather than easing it back gently. That seems to provide enough momentum on the ball valve and pedal mechanism to get the ball valve to rotate into fully closed position. But that seems an inelegant solution, at best.
I noticed in the troubleshooting portion of the manual that item #1, "Water will not stay in bowl," that tightening
the clamp nut was the first suggestion.
In item #2, "Plastic flush ball will not close completely," the first suggestion was to loosen
the clamp nut.
I ordered a new set of seals, and I find the package the new seals came in recommends the clamp nut be tightened to "about 65 inch pounds."
Clearly, the unit is sensitive to the tightness of the clamp nut. But I don't seem to be able to find the sweet spot between too tight and too loose. The ball just won't close all the way (unless I let it slap back).
Interestingly, the second suggestion under #2 is to check the spring tension by suddenly letting up on the flush lever. If it doesn't snap back, the suggested remedy is to replace the spring cartridge. Fortunately, I seem to have plenty of snap, so I don't think I need to mess with the spring.
However, I have found that there is a lot of play in the ball valve. After I ease the pedal back up, the ball stops and the pedal comes to rest, but I can further rotate (with my hand/fingers) the ball another 3/4" at least, which seals it. (Obviously, that's only going to happen on the bench, not with the toilet installed.)
