My loo was installed and the seat fixed before the pipework was boxed in behind. The seat is supposed to be the kind that closes quietly. The trouble is it does this in preference to staying up, which is no problem for female users but very irritating for males. I'd like to change it, but can't get at the screws as they're out of reach by a human hand or any tool I can think of. Short of removing the woodwork boxing in the pipes, are there any alternatives?
