        We just moved into a home with a 4 year old gas water heater that makes horrible noises: it sounds like a bag of rocks clanging against a metal tank. It does this even when you are not running the water. The noise is so loud you can hear it in the house 25 feet from the tanks (which are in a closet against an interior wall that is in garage).

        What could be agitating this tank?

          Dirt settling in the bottom of the tank will cause noise:
