: : I recently completed a total bathroom renavation. The new toilet I installed has an abrubt shutoff when it fills up. This results in what sounds like a bang in the wall. As I am also renavating the adjacent master bedroom bathroom I have still have access to all the involved cooper pipes. All the pipes seem to be solid. The same lines that feed the toilet also run to a stand alone shower with a pressure balancer tap. I have tried further bracing the walls and the pipes but I still have the noise. Right now I'm lost to what could be the cause. Please help.
: 1st: do you have an air chamber installed on every fixture? Traditionally, it was often the case to omiy an air chamber at the toilet (but still wrong) because of the slow closing nature of cpmpound lever ballcocks. But many of todays ballcocks employ a positive stop---an abrupt halt to the flow of water. If you have recently remodeled and have access to these pipes from the bedroom, I suggest both of these ideas. A GREAT ballcock to use is made by Wolverine Brass, Model 50625. It is available from plmg.shops only, but it is the only one I use. Good luck. And DO NOT overtighten you water lines with clamps to the wall studs; allow them some movement for expansion and contraction.
Ward when you refer to an air chamber are you refering to a line running close to the toilet that is capped off. If so no I don;'t have one on the toilet. If I do install one, should it be as close to the toilet as possible and how long should the pipe be?
