Just completed my bathroom remodel. The shower squeals for a few minutes after turning on the water then the squeal goes away. The noise
sometimes starts right away but usually after it has been on a few minutes. It doesn't last long but can be loud and annoying. I removed
the shower head and flushed the water line. Thought it might be debris. Could not get the head apart to clean it so I reinstalled it. I checked
the water pressure and it reads 50 psi.
It may be in the shower valve itself, but if not, it could be turbulence in the head. The only way to determine which is to use a different head to see if it goes away.
Thanks, I'll try replacing the shower head first. Will let you know how it goes.
I installed another new shower head. This one has adjustable flow. It squeals as bad or worse than
the original, in any flow pattern. The control valve is new as well as the copper pipe from the valve
to the shower head and spout. I installed cpvc from the valve to both supply lines,which are also cpvc.
What do I do next?
