Just roughed in a residential water supply system. Inlet pressure was rather extreme at 110-135psi so obviously a PRV install was needed. We are now experiencing a low to moderate (72 dB) pulsating noise at the PRV when water is flowing through the system. Below is a link to a video that demonstrates the situation when a 3/4" branch line is opened 100%. The pulsating begins when the 3/4 line is open 75% or more.
The PRV does regulate the pressure properly, but its annoying to hear.
I have checked that the valve it is indeed oriented properly.
I called the manufacturer (Resideo Braukmann) and they had no insight to share. They told me to try and turn the outlet pressure up or down. When turning the pressure up it made it worse, when turning it down it reduced the noise a little but the pulsation was still present.
Seems to me like there is some issue with the valve mechanism of the PRV? Perhaps it is hitting back and forth when water is flowing quickly?
Im thinking the next step should be to disassemble the PRV to see if there is any identifiable mechanical issues. Any other suggestions? I do have another one of these exact same valves that I had planned to use on another project. Next chance I get I plan to try and swap it out to see if it is indeed just a faulty valve causing the issue.
PRV model: FK06-102-DUS-LF (from what I understand this is the exact same product as DS06-102-DUS-LF however it has the addition of a filter element below)
