Pool of water under the toilet cassette. Thetford. (1 Viewer)

[Dai Motorhome]

When I was emptying the toilet cassette I noticed a pool of what seems to be clean water in the recess where the cassette is fitted. I can't see any obvious source of the water. Anyone have any similar experience?

Possible drain off from rinsing the cassette after use, or even a poor seal to trap. Check other pipewoork for leaks when flushing takes place.

If the seal has become hard, remove it and wash it in warm water to soften it a bit. When you put it back lubricate it with a little olive oil. If it is too far gone replacements are readily available.

How do I remove the seal?

i had a similar thing last year and it turned out to be a one way valve that is fitted on the flush supply up inside the actual toilet unit . it is plastic and had cracked during the winter lay up, the fresh water then found its way down into the cassette locker. the part was around £15 but it was a sod to get at in situ lots of cursing and swearing sorted in the end though !!! garry

You first need to remove the capping piece(s) which are screwed onto the cassette. That varies a little between models but will be covered in the Thetford manual. If you don't have a manual they are available as PDF downloads from Here.
