Every so often (2 or 3 months) I'll go to use my Thetford C250 and the bowl will be full of flush fluid. The first time I assumed it was a faulty flush button so I changed that it happened again. Next I removed the fuse for the full light still did not solve.
Then I thought it could be siphoning so I put less in the flush holding tank and I thought this had solved the issue but this morning I awoke to a full bowl again.
Any Ideas please.
Thanks
