Thetford 402

Can you overfill the flush tank? I ask as I have the problem back of the red flush coming out of the front bottom bit into the shower tray?

Had problem last year with water coming out and despite advice from Mark, Dolphin sealed the gap, well I have removed the mastic as I could hear water sloshing about and it was well full and almost filled the shower tray
What is going on?

personally I ve given up on the tank and use a spray bottle instead - doesnt fill the cassette so much!

Thanks, that explains it. As you say, not much use is it  

Suppose a fix by Thetford is due, some hope of that.

Yes that is the one. I can only think I over filled it, as not had the problem before. I would have thought that the tank was sealed, the water was not at the top of the level tube and it was still looking like it could take some more. 

Drained some off before moving today and not sign of leaks.
Thanks for all your inputs.
