water heater noise (sounds like popcorn popping inside!)
Posted by Ruth on August 05, 1999 at 12:40:41:
I have a water heater from Sears (1987) and it started making noises two nights ago. The noise sounds like either a shoe in a clothes dryer, or popcorn popping. When the heater turned off, the noise stopped. But then when the heater came back on, the noise started again. But, it seemed like it fixed itself by the morning and I haven't heard any noise since then.

I am in Maryland and there is a drought at the moment, could that have anything to do with it? My uncle thinks the noise might be rust banging around. If so, is that serious enough to have to get a new one? Help!Thank you,
