I am going to replace my water heater. No problems, but it is 24 years old and I figure it is pretty full of debris.
I shut off the inlet, opened the drain, opened a few hot water taps to act as vents, and nothing happens. I opened the inlet and water comes out the drain. Shut the inlet and nothing comes out.
Shouldn't it just drain out? I suppose I could put compressed air on the inlet, but that wasn't necessary on other water heaters I have drained. Any suggestions?
