Hi! The water pressure to our home is too high, the pipes are rattling. I have read some of the other postings, and would like to know if installing a pressure gauge (as recommended) is an easy thing for an individual to do - or does one need a plumber?
Thanks for insights!

You can add a pressure reducer but lets start with your current water pressure, normal is about 45 psi. The rattle could be water hammer but I'll wait to hear back from you before I go in the wrong direction.

Thanks for responding. It is definitely a water pressure issue. It is a new system, and the water company sent a pressure gauge. Is this something my husband can do?

A pressure gage won't fix the problem, only measure it. To lower the pressure, you need a pressure regulating valve, and to set it, you do need the pressure gage.

Whether you husband can instal it depends on his skill and the type piping you have. Almost anybody can work with PVC. A little experience helps with copper. PEX isn't that DIY friendly either. They are sort of expensive, but there are ''Shark's Tooth'' fittings. They are quite easy to use with copper, PEX, and CPVC. Ace Hardware and plumbing supply house have them. I haven't see them elsewhere.
