We have just moved to a lovely house, but unfortunately the toilets have no access to the cistern, one of which has gone on the blink. They all seem to be of the same manufacture and display just a small chrome button embedded in the tiles. Two of them have a lid, which is where one would expect. However the lid is glued solid. We cannot think of a way of removing it. The third has no lid, so the only access appears to be gained by smashing the tiles.
Has anybody encountered this problem before?
