Hi,
We are having a problem that was isolated to our check valve at our cold water input to our hot water heater.
Whenever we have a quick shutoff of water (toilet, sink, dishwasher, clothes washer etc...) the check valve has a thump/bang that is fairly noticeable. The biggest problem is this valve is right on the wall next to my child's bed - so he hears this thump or thump/thump that sounds like someone knocking on the wall - the wall is almost acting like a speaker and amplifying the sound. I am having my plumber look into it at the moment, but so far no solution has been determined.
So since I have received such great help on this forum over the years I wanted to ask!
Our hot water re-circulate loop connects to this same area as well, however it does have a proper expansion tank above this check valve. The current check valve is brass and sitting horizontally.
I would love to find a different check valve that is silent - I will need to get the actual valve type spring or swing, size etc... figured out and will take a picture later today.
