Hearing random banging from pipes since a new pressure release valve installed. Could pressure be too high?

About two weeks ago I had a new pressure release valve, new water heater, and new expansion tank installed. I started to notice about 5 days ago that about every five minutes a “bang” sound comes from the basement - it does sound like a hammer striking the pipes, but it doesn’t happen when a faucet or appliance is on. Could the plumber have set the pressure too high on the PRV for the pipes, causing this noise? The gauge on the device says 67 PSI and I’ve read that normal range is 40-80. We have an Aquasana water filter hooked up after the PRV, which I’d expect to lower the pressure a bit too - so the PSI doesn’t sound excessive but the noise is driving me nuts and making me worried. submitted by /u/brownmatt [link] [comments]
