I have a question regarding thermal expansion.....
If you have thermal expansion going on in your water lines (no expansion tank), does it immediately dissipate when you turn on a water valve?
I am having with vibration/growling noises coming from my pipes. (explained in great detail in another post that didn't get much attention) I can turn on a trickle to any faucet, and my pipes vibrate/growl. I can let it run at a trickle indefinitely and the noise never stops. I can turn on the water full and the vibration stops but immediately comes back when I turn the faucet back to a trickle. I would think that if thermal expansion was the culprit, the noise would take considerable time to come back after opening up the faucet for a while. Am I wrong?
The PRV has been replaced twice in the last several months. The original one was a Watts N35B that went bad after 14 years. I replaced it with a Cash Acme EB-45 a few months ago and then with a Cash Acme EB-45DU a couple of weeks ago. Since the new valves were put in, I have experienced a wide variety of sounds ranging from high pitched tuning fork sounds, vibrations, growling, etc. Could 2 units be bad? Both are in working order regarding the pressure reduction.
I am on the fence between bad PRV (or wrong type, bad quality) and thermal expansion being the cause of the noises.
Oh... and by the way, the city water pressure is around 150 before the PRV in my house. The water dept. confirmed the pressure is high but normal for where I am located. (down in valley)
Any help, thoughts or ideas would be appreciated.
