I've recently flushed my hot water tank trying to get rid of the banging and poping sounds. I drained the tank and also flushed with water until clear (didn't have that much build up). I am still having the same banging/popping sounds. Any ideas????
have you had any other work done recently? maybe new water meter? some new meters have check valves built in that would now require you to install domestic hot water expansion tank on cold water supply to hwh.
