In response to Re: Having two PRV installed.
I once had a customer that had poor pressure. I checked the PRV and there was poor pressure to it. After digging around a bit, I found another PRV ahead of it which had corroded to the point that the top fell off and turned the PRV off. You do not say if there was some indication that the other valve was there, or that the plumber should have known about it.

: I have recently wrote because we were getting very low water pressure after a "licensed" plumber installed a pressure reducing valve. We had them remove the valve last week and now we have extremely low water pressure and terrible water hammer. After noticing a small amount of water in the basement below where they removed the valve my husband tore open the installation and we can't believe what we found. Just ten inches below where this plumber installed the PRV was a PRV.

: We are having another plumber come out tomorrow and replace the existing PRV and then I am writing the owner of the first company a steaming letter.

: My question is: Can have two PRV's cause any damage to our pipes? We have been living a plumbing nightmare since December.
