Hi all. Just wanted other plumbers experiences with leaking close couple toilet cisterns and their solutions, (preferably without squirting silicone all over the place!) . Had a number of theses recently and they are always a pain to solve.
So when all else is sealed on the cistern, flush valve exit, inlet valve, and pan connecting bolts, a leak often can still be found from the seal around the doughnut pan washer. Symptom is the inevitable leak from the pan connecting bolts hole in the bottom of the pan after a flush.
Replacing the doughnut does not cure the problem, realigning the toilet cistern does not seem to help either. The only cure for the stubborn ones I have found is an over sized cradle on the flush valve outlet, with a longer screw threaded part so that it goes into the pan further. But these are not available for all flush valves, and I don't think they are for the common Ideal fittings. Any solutions out there i'd be interested to hear.
