noisy pipes

[dirtyhippy]

I was contracted to fix a squealing noise in a restaurant. i had originally thought it needed hammer arresters but that did not fix the problem. its only coming off of the hot line on the sink sprayer. i still think it could be something with the water pressure. can anybody tell me what this could be?

Did you check for a flow restrictor?

[dirtyhippy]

havent had a chance to check for restrictor, going back to try to fix in a few days could it be the prv?

[Sylvan Tieger]

Yes the PRV could also be malfunctioning and cause sounds to travel.
