Rant: Last night, I noticed some water on the floor in the garage. Looked, and the lining of my old gas water heater was giving way. Replacing the water heater today. Doing it solo, but thankfully I am able. Rave: Having noticed it early, I was able to switch off water and gas to the heater, and drained the tank manually via el garden hose. My stuff didn't have a 40 gallon bath.....a clear win. I got lucky.
