Water Pipe Rattling at Water Heater

Jan 09, 2006 3 Replies

If I turn a faucet in the house off quickly, I hear a rattle. I traced this noise back to the water heater. If I shut the valve off that feeds the water heater, and repeat the test, the noise does not occur.



I have a 2 year old water heater, that I believe has a built in Heat trap/valve. I believe this related to my problem.



Is this normal? Could this valve be going bad?

Sounds like water hammer.

Lowes or any home improvement store would have various shock absorbers that will fix it.

It may be, but it is only occuring at the water heater. That is why I am concerned.

I was thinking about this more, but isn't hammer caused when you shut the water off? The reason I ask, I am sitting here and my wife is running a bath upstairs. The water is on and moving quickly...The rattle is constant. I'd think hammer would not be an issue with the tub spigot on full blast.
