I've recently fitted a new toilet (Twyford's Albany). The problem is the seat won't stay put but gradually moves out of alignment. It came with plastic washers and they tend to slip even with the wing nuts tightened as far as I dare.
I tried replacing the bottom washers with domed rubber washers to centre the fixing studs in the holes, but then I can't position the seat in the right postion. The postion is quite critical, because the seat is quite wide and only just clears the cistern handle. And anyway even with domed washers the seat still tends to shift.
It seems I will have to stick with the plastic washers and use some sort of sealant or mastic to hold them in place. Any suggestions what I should use? What do you professionals do?
