I'm not a plumber, but my pipes "bang" when there is "Air Pressure". Typically after turning off the main water switch or replacing a hot water heater.

I would wait for a "Professional" on this one.

I Know this is an old post but did you ever get this figured out. I'm having the same problem

Hi kahalaw and welcome to The Plumbing Page at AskMeHelpDesk.com
Do your pipes bang for 10 minutes or is it a single bang? Please list your complaint in detail. Thanks, nTom
