Hello,

Been having trouble with my Dometic 310 toilet intake water valve sticking open partially wasting precious water into the black tank, just like to know if how common this, just had the old valve replaced, the new one did not work any better, does Thetford toilet valves have the same problem.

Thanks

No the fill valve should not leak. If you replaced the valve with a new one and it still leaks then either you have some foreign matter in the valve that is causing it to be partially open. Or your water pressure is too high and forcing water past the valve.

Does the leak happen only when hooked up to shore water? Or does it also leak when running the fresh water tank and water pump?
