In response to Re: Hot water heater "knocks" with running water
: I just moved into a new home, and the hot water heater periodically "knocks" while the water is running. It is very loud and I can hear it in other rooms. This is an older gas heater from Sears (40 gal I think) and that's all I know. Is it about to die on me or is it something like air in the tank? Thanks! : Bryan your water heater has mineral build up in the bottom. It is not a dangerous condition. sometimes draining it can help but not very often. invest in a new water heater if it is that old, it may be worth the peace and quiet.
