Hot water heater rumbling
Posted by Charles Lam on November 06, 1998 at 12:33:36:
Just moved into a new home, and found that my hot water heater makes a terribly loud rumbling after hot water was used.
The sound is sort of a rumbling and poping noise.
What is actually happening and how can I fix it?
The heater is about 10 years old. When do they need to be replaced?
