Banging sound in pipes . . .

[Dan]

at a natural gas water heater. It is not the sound you get from buildup at the bottom of the tank. It sounds like someone is hitting the pipes with a small metal hammer. If you put your hand on the pipes you can feel the shock vibrating the pipe. It happens late at night when there has been no use of hot water and the burner has not been on. If the main supply ball valve to heater is turned off, the noise stops. Sounds like it is pressure related. Ideas, suggestions, buy a new house? Thanx in advance.

There's not enough information here to diagnose properly, but, I'm gonna' immediately suggest that you add an expansion tank on the hot side (of course) of your water heater. This is not for rookies. Hire a plumber.

You need to install something called an "air hammer". Its like an upright cylinder filled with air to soften sudden draw or shutoff. Even a slow draw into a toilet or something in the middle of the night can make it vibrate the pipes.

Depending on what kind of pipes you have, you may be able to take about the pipes and install this thing yourself. They'll have them at your local home store.

Make that ditto for me. I can only conclude that plumbers must make their cracks show on purpose.
