Our 15 year old house suddenly developed water hammer issues( at least I think that is what it is ). we had some work done on our pipe line.The problem developed after that.
Whenever the washer works I hear a banging sound in the kitchen, especially from the back of refrigerator.
( washing machine is next to kitchen)
We have a pressure reducing valve and a new thermal expansion unit. ( the plumber said the water pressure is around 65 ).
I called the plumber and he said it is nothing to worry about. But I am kind of worried & quite annoyed by the loud sound .
Is it water hammer or something else?
Can we do something about it ?
Or is it wise to ignore the problem ?
will reducing the water pressure to home will eliminate the issue ?
Thanks in advance
