Pipes vibrate as toilet fills
Hi, Hoping you can help. Have a very loud and visible vibration of the water pipes while a basement level toilet is filling. This problem recently started, about the same time as a hot water heater was replaced by plumber, which led to the Pressure Reducing Valve being replaced by me (not a plumber), replaced the fill valve, and started up the sprinkler system for the season.
So far I've tried:
1) found one loose clamp on the pipes by the WH and PRV, secured it
2) drained the whole house (shutoff main, shut off water to HW, opened all faucets and flushed toilets, starting at the lowest level. Including the outside spigots and sprinkler drain. Turned on main, waited for no air sounds and started turning off faucets starting at the lowest level finishing on top floor. Turned on water to WH)
3) pressure is about 50, drops to 20-25 while toilet fills
There doesn't seem to be any hammering sound at the closing of the valve, but do hear like a 'whoosh whoosh' before the vibrations begin - these continue very loudly till the fill completes. What else should I be trying before calling in another plumber? Your time and feed back is appreciated. Thank you!
