UPDATE: 'Vibrating Pipes When Any Source is Shut Off'. Upon the suggestion of
Trader_4, I checked into the water pressure regulator. I went back onto Home
Depot's website where I ordered this Sharkbite regulator through to check out
the reviews, and sure enough, there were several customers that bought the
same unit and had the same complaint. Unfortunately these reviews were posted
after I had already bought and installed mine. In the beginning I had no
problem, it developed later on. Anyway, Sharkbite had suggest that the
adjusting screw be turned one full turn up or down, and that should eliminate
the noise. So, I went up. It did lessen it, but the vibration was still there.
So, I turned it another full turn up. The vibration is faint, and only lasts
maybe 5 seconds compared to the original 30 second span it did before. I can
live with this until I replace the regulator. I notice at the gauge the line
pressure rose from just past 50 lbs. to 70 lbs. I will have to increase the
air pressure in the water heater's expansion tank to match. Thanks again to
Trader_4 for giving me a direction to go in.
