I live in an apartment where the furnace and water heater are in a closet on the first floor. Whenever my brother (roommate) or I shower, when the hot water heater is refilling it makes this strange noises, like there is a bunch of marbles bouncing around in it or something, or alternately it could be described as some sort of creaking noises that stop after a few minutes.
What is causing this? Its a typical gas water heater.
