Hi, after a few months of frustration I'm looking for any ideas to solve my water hammer problem.
I remodelled our upstairs bathroom about 4 months ago. Did the plumbing myself which was not particularly challenging...basically shifting a toilet slightly and moving a sink from one side of the room to the other (now beside the shower-tub). Without changing any of the fixtures, I suddenly started getting an extremely loud water hammer noise whenever the sink and shower are turned on/off. The banging is loudest near the shower faucet area.
I have tried (without success):
- replacing and lengthening the air chambers behind the sink and shower
- replacing the chambers with arresters (basic piston-type, from local hardware store)
- draining and refreshing the entire house system numerous times
- replacing the pressure balance valve in the Moen shower faucet
- replacing the cartridges in the sink faucet (8" Blanco model)
- securing the pipes against the studs
At this point I'm wonder if it's the actual piping layout (all 1/2" copper), or a pressure change caused by the sink and shower now being beside each other?
Suggestions welcome, thanks!
