I had an addition to my house put on about a year and a half ago and now have incredible water hammer problems. I do not know if the two are related?
I have been living in my house since 1988. When the banging started about 3 months ago I tried to ignore it until it sounded like a sledgehammer! I called the well expert out and he indicated there was a leak on the internal 1 ½” pipe (as opposed to the casing which is O.K.). He said the internal pipe in our area lasts about 30 years then we can expect problems. I gave him $500 and let him do his thing. He may have solved one problem but the other is still there.
I could not find the Check valve and pray my plumber did not put it under the driveway!
Does anyone have any ideas on how I should diagnose this situation?
Thank you!
