    Humming noise after changing PRV
    I had water pressure of 150PSI. I figured PRV is gone. So, I changed my PRV at the front inlet. Water pressure is 60 PSI. but, I am now getting humming noise when I turn on any faucet/shower in the house.
    If I don't open main value (before PRV) fully, pressure gets down to 50 PSI, and humming noise is not there while water is running. But, humming is still there for few moments when water turns on and when turning off.
    When I open main value fully, pressure is 60 PSI, but humming noise is always there when water is running and it is louder.
    I checked pipe, none is loose, so pipes aren't banging.
    Humming noise is more towards the front inlet (I can even feel wood floor vibrating near inlet).
    Can't figure out what/where is wrong?
