We've caught the Thetford several times right before it overflowed because the lever doesn't come back into place completely. I've read of numerous problems, even after replacing the spring and lever, so we're just going to replace the toilet. Camping World currently has a Dometic high profile 320 series gravity discharge toilet for $216.79. Does anyone have that toilet?
Any problems changing from a Thetford to a Dometic?
