I have noisy pipes in a house built in 2007 - banging when we turn off the hot water in an upstairs sink and loud 'bang bang bang' when the washer switches from cold to hot. We have a hot water circulating pump and two water heaters in the garage.
Upstairs on the sink, when you turn off the hot water there is a banging above the adjacent shower. Pictures taken during construction show no known pipes above this 2nd story bathroom - only attic. The plumber said that it is echoing through the space between the studs inside the wall. (?) They opened up the sheetrock in a 1st story bathroom directly below it and braced the pipes - no change. We think it is air that is trapped in the pipes.
We have (several times) cut off the water at the street and opened all faucets - this sometimes softens the noise but does not eliminate the problem.
The only answer the builder (who has been good to us) and the plumber have come up with is to change out the cartridges in the 4 showers in the house. I don't see how this would help when the noise happens when we turn off the sink?
Can anyone explain this or give me any other solutions? Does anyone think there would be pipes over a second floor shower that would cause the banging and we should go up in there?
Thank you!
