My sealand toilet no longer holds water in the bowl. I have cleaned the seal area as best I can. Anything else I can do before rebuilding the toilet? How big a job is that to do? Thanks
Same trouble with my 2015 Montana when we got it and the dealer would not replace the toilet because of Thetford said it needed a new base. That did not fix it. Finally Thetford sent me a new toilet with China Bowl etc. I had already bought a Dometic to replace it with. Wish you were not so far away I would give you a brand new toilet that has never been taken out of the box.
