I have some water hammer noise that seems to be from the incoming line. The water company refuses to do anything with the meter saying they have never had a meter do anything like this. My plumber says the meter is probably it. I am getting very frustrated. I would like to fix the source of the water hammer but expansion tank or PRV seems like my next best option. My pressure runs 65 - 70 PSI. I am thinking an expansion tank right as the line comes into the house might be more appropriate than a PRV. Looking for some other opinions...
Seems to me the PRV might not respond quick enough to the water hammer and if it did would make the pressure surges worse in the incoming line. I have an expansion tank at the inlet to the water heater but it is some distance from where the line comes into the house.
