I'm having a real hard time with this one: I recently replaced both water heaters in my house at the same time (both are Whirlpool 40 gal. natural gas).
Right away we noticed that whenever a hot water valve is turned off (sink, shower or washing machine), there is a short but noticable rattle coming from inside the wall (directly behind the water heater).
I tried draining the the water from all the house pipes to ensure the air chambers weren't water logged but to no avail.
Any ideas what could cause this?
