Water line "hums" - DIY Chatroom

downunder · 05-27-2009, 09:14 PM

I replaced my gas hot water heater several months ago. Since then I have noticed a hum when I run the hot water.

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.

It is humming because it don't know the words.

I'm sorry I couldn't resist it.

I'm not really a breaker.

Do you mean like a faucet in one of the sinks or something? I did have a couple open to bleed the line. Don't remember exactly when I closed them other than after bleeding the air from the line after filling the heater. This seems to happen when I run about every faucet.

This is something I had not even begun to suspect. Thanks.

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.

Now I'm on the same page with you. My apology for taking a few days to acknowledge your reply, been busy with a couple of other things. I'll try this as soon as I can.
Thanks.
