While
insulating the water pipes, I took some time to crack the drain on the water heater and get some gunk out of the bottom of the tank. There wasn't much in it, and I am a bit surprised about that. I doubt this has been done to the heater ever. Perhaps I didn't do it right? All I did was drain some water from the bottom. Are you supposed to drain it all the way, then let the cold water splash in and blast the bottom a bit? That does seem like a better way, but it also drains all my hot water.
