Hi folks, new to forum and need some help/advice.
Just installed new pressure regulator at son's house. Installed ball cut off before and after regulator. Replaced his old regulator because pressure was jumping to 160 and popping P&T on hot water heater. Everything checked out find before I left his house (pressure at 50psi, no noise). Got a call from Son and he says every time water is turned on (anywhere in house), pressure regulator has a srill whistle noise (heard it over phone, rather ear peersing!). Any one got any ideas/suggestions?

Sometimes the neoprene washer is not set in its cup properly.
If it's brand new I'd take it out and exchange it where you got it for a another one.
What brand is it?
If you try to take it apart and fix it yourself you may void any warranty and possobility of exchange. Call the place you bought it from and ask them.
See picture. I highlighted washer w/ red

Check your toilets for this humming noise.
Might not be as severe.
I've heard PRV hum but it wasn't the PRV

Did my comment help?

Yep, changed it out yesterday morning. Exchanged the one I had put in for a more expensive one with separate strainer basket. Only problem I had is getting all the water out of the line but everything held and no leaks and son said no noise last night. Thanks for the info. In my 60+ years of home improvement projects, never ran into this type problem. Learn something new everyday. Thanks again!
