My dometic cassette toilet has given recurrent problems with leaking. It can be dismantled and silicon grease applied to the seals which improves matters for a time.
Never again … will we need to rescue the toilet roll!
We all know the primary use of the toilet cassette, but I saw someone had found a new use, which I now copy.
