The tenant at our previous home called me that they have observed water pressure issues past 2-3 weeks. When a faucet is open when someone is showering, the pressure reduces too low in the shower until other faucet is shut. Couple of days back, they reported that they are hearing knocking/thumping noise in a wall behind master bath shower even when it is not open.
I suspected PRV issues. This home was built in 2001. I connected water pressure meter to outside faucet. It showed 100-110 psi. Then I located PRV and turned the screw on top counter clockwise to reduce pressure. That didn't make any difference. The pressure stayed at 100+ psi. Then I turned water off completely at city main meter inlet. Opened all faucets and let them drain so that air goes in. Then opened city water inlet and the closed all the faucets. Waited for pressure to stabilize. The water meter still is reading 110+ psi.
Attached is picture of PRV buried in ground. I don't know if it is Watts/Wilkins/Whatelse brand of PRV that I have.
I am wondering if I need to anything else to diagnose the problem. Is it classic failed PRV or something else?
If you think it is PRV gone bad, do I need to replace the whole thing or are there spare parts to rebuild the PRV?
How do I know what brand/model of PRV do I have?
I appreciate your help.
Thanks
