Water line "hums"

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.

Water line hum

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

I'm sorry I couldn't resist it.

I'm not really a breaker.
