I had a plumbing company install a pressure reducer on my house and when
they turned the water on it started causing bad water hammer. The whole
meter was shaking back and forth and causing the pipes to band inside. The
company is telling me that the problem is in my house somewhere. I had to
adjust the pressure to right at 85 psi to get the banging to stop. Is there
anything I can do or could tis be design flaw with this reducer? It is a
platic unit that is light brown w/ a red screw top to adjust the pressure.
Also what pressure do I need to be worried about causing damage to the
Thanks for any help you guys can give me.....
