squeak when water stops running

Have a 3-floor townhouse and most every time a faucet, or toilet, or dishwasher shuts off, I hear a brief, high-pitched, squeak. Any solutions someone can suggest? Do I need a plumber? I have a pressure regulator already.

Odd issues like this usually are the result of either:

1) Too-high water pressure. Your PRV might not be working correctly or could be set incorrectly and be allowing the pressure to rise too high. You'll need to connect a pressure gauge to a faucet and make sure that you're no higher than 60-70psi.

2) A loose or worn washer in a valve somewhere. I didn't believe a little rubber washer could cause so much noise until I heard one for myself. Either the washer vibrates or causes some turbulence in the water which makes rather loud groans, squeals, or vibrations. The hard part is finding the valve with the loose washer - could be a main valve, as washer in the PRV, or even a under-sink or under-toilet shutoff.

I'd probably start with #1 and testing the pressure. A $10 pressure gauge will tell you quickly if that's an issue or not.

Where do you hear the squeak?

I have heard loose pipes in the wall squeak or bump when water is quickly turned off.
