Popcorn noise out of hot water heater
Posted by Dave Bertone on May 08, 2003 at 17:26:23:
We started hearing a loud popcorn noise from the hot water heater after hot water was used. The company I have a service contract with states this is normal - cold water hitting bottom and heating up. Is this true? We have not heard it before in the 6 years we have lived here. Please help.
