Singing B&G PRV

You may have a system hum and it may not be the PRV. The noise could be caused by a toilet and the noise could be transmitted to another location. Sort of like the paper cup and string walkie talkies we made as a kid. A water hammer with multible on and offs cause the pipes to sing ...


Sometimes a domestic expandtion with a tank charge not matching a system pressure could cause the same noise. I don't know why but seen it a few times.

Try shutting off supplies and see if noise stops to find the culprit ..
I have enough experience to know , that I dont know it all

    Never ran into this before

    I have a B&G pressure reducing valve on a steam system (feed water line to the condensate return tank) that sings, howls, hums or whatever you want to call it. Is this a defective valve or could there be something going on with the water pressure in the house. It's hooked up to a city water system that provides about 50psi.


  • I have a B&G reducing valve in a system which also sings. Luckily it is installed in a hot water system, so it only sings on the rare occasion of adding makeup water. Its been doing this for about the last 15 years! Otherwise, the valve works fine without any leakage, so if your valve works ok otherwise, I wouldn't worry about it.

    One issue, might be symantics

    The B&G valves are more for water...the Hoffman line from ITT is more for steam...if you're running it on a steam system it might not be handling the temperatures/pressures the same way it would on a water system. or maybe the seat isn't closing..which valve do you have? Do you know the model number??
