My upstairs shower has an annoying water hammer issue when turning the water on/off “upstream” of the shower. For example, when water is turned on/off for the faucet (or toilet) in the same bathroom, the shower will “knock” right at the valve. I’ve been able to ensure that the valve itself (and supply lines) are secured, and also confirmed that there are not any air chambers installed, so I think that isolates the issue.
I could access the shower valve area itself on the backside by opening up the drywall, but right now I have open access to the supply lines in the basement. Can I add a mechanical arrestor (or something) to those supply lines to avoid working directly at the shower valve? All the accessible supplies are recently installed Pex, while the upstairs shower supplies are copper.
Thanks in advance for the good advice!
