Water pressure in my home was at 120 psi. I replaced the existing PRV with a new one and my water pressure is currently 45 psi. Now when I run water I get a loud hammering/squealing noise from the pipes while the water is running but it doesn't happen all the time. The most consistent way to see the issue is when using the fridge dispenser it starts to do it once you almost fill a whole glass. Then it will stop as soon as you stop the dispenser. It occurred while using my washing machine as well. Other than that I've only noticed it once with my shower and once with a faucet over the span of a week. The noise itself is very loud and concerning but it stops as soon as the water is stopped.
