I have a Moen shower valve in my home's main bathroom. I am currently renovating my master bathroom and to re-run soem plumbing and rough in the new shower valve, I had to turn the main house valve on and off a few times. Now the Moen shower valve in the main bathroom moans when I move the lever to the hot side. It is a single handle and it seems to make the moaning noise anywhere along the warm water side.
Any ideas why or what I can do to fix it?
Good answer Jerry!
The problem with that answer is that if it is a Moentrol valve the noise could be in the pressure balancing spool and a new stem will not cure it.

I just got around to replacing my Cartrige. Last week I attempted to break it free with the plastic "tool" included in the kit. No way would it budge. I called Moen and they sold me the REAL TOOL for $25 and shipped it FedEx.
I sprayed the old Cartrige with some PB Blaster 2 days ago. Tonight, With the REAL TOOL it came out. That tool works like a bearing puller where you can apply pulling pressure and at the same time slightly twist the cart. That did the trick.
