I laughed out loud when I read the comment on the "Removing the Hot Water Heater Plug"
One night when the temps were going to get real cold, I thought by running the hot water till it came out cold would empty 90% of the water out of it. I just planned on blowing out the rest with an air hose hooked up to the water lines.
When I unscrewed the Hot Water Heater Plug, I too was showered in scalding hot water that was still in there.

I should mention that Cindy and I were ready to go out for the evening when I thought of this and said "Hold on, let me go drain the water lines real quick"
The temperature was hovering right above freezeing and here I am soaked from the waist down standing in the snow.

Great to know that I'm not the only clutz in this Forum...LOL
