Water Hammer Arrestors

Author: george 7941 (Canada)

Just had a text from a customer - she has vibrating pipes inside walls when the fridge water valve turns off and when the tub valve on the second floor turns off.

I expect installing an arrestor under the kitchen sink at the feed for the fridge will eliminate the hammer at that location.

What can be done about the tub? There is no access to the pipes anywhere except in the furnace room in the basement. The rest of the basement is finished. Installing an arrestor two stories away from the tub isn't going to help, is it?

Author: Curly (CA) If the tub valve is old school compression type stem it could be a loose faucet washer on the end of the stem causing hammer..... Otherwise as Bern said correct and correct.

Author: george 7941 (Canada) The tub valve is a Delta Monitor with the blue cartridge. I had changed the cartridge a couple of months ago for dripping, now it makes me wonder if there is a relation. I will try another cartidge and see if it makes a difference.
