Water line "hums"

1454 Views 6 Replies 4 Participants Last post by  4just1don
I replaced my gas hot water heater several months ago. Since then I have noticed a hum when I run the hot water. :eek: The wife says she can hear it sometimes when the cold is running but I can't. I have not been able to pinpoint where the sound is coming from because it seems to echo through the whole system. Water delivery is fine. Hmmmm.

If you have a shut valve that you closed during installation, it may be a loose stem washer fluttering. If it is you will have to shut the water off pull the stem and replace the washer.
I mean an in-line shut off valve. They seldom get used and the seat washer deteriorates then when they are used the washer comes loose.
