So about 7 months ago, I posted this thread:
Why are my pipes wailing?. I had a wailing pipe sound that would start up whenever someone would turn on a faucet. This wailing sound started a week after a new PRV was installed. It was resolved when a plumber came in and adjusted the PRV to lower the pressure, and ran all the faucets in the house for a few minutes to try and get any air out of the pipes.
Well, 7 months later, the wailing sound is back again. So I tried to replicate the plumber's fix. I ran all the faucets in the house for a few minutes, then turned them off in order of distance to my PRV, with the closest being turned off first. That didn't fix it, so I adjusted the PRV, turning the screw counterclockwise in order to reduce the pressure. That didn't fix it either.
The problem goes away almost completely if I turn off the water supply to the Toto Drake ST743S toilet in the master bathroom. At this point, I am exhausted with trying to fix this problem, and would settle for eliminating the effect instead of trying to find and fix an elusive cause.
So if turning off the water supply to the toilet makes the problem go away almost completely, does that mean that I should replace the fill valve with this replacement unit, and follow these instructions?
Thank you so much for any help. If I never wake up to another sound that's reminiscent of a distant, muted siren, I will be eternally grateful!
