We're all excited, about to go out on our first trip of the year and just got finished dewinterizing.
When winterizing, remove the anode and flush debris out of the water heater tank with a hose. I say to myself, ok, sounds easy but not very important. WRONG! Today, after washing the antifreeze out of the lines, our kitchen faucet wasn't running. Gunk was blocking the aerator. I went back and unscrewed the anode plug.
Important! Always make sure there is no pressure by relieving it first, there's a relief valve above the anode plug. If you don't, you may get a faceful of hot water. When de-winterizing,the odds are that it will just be cold water. (Don't ask me how I know, I'll just lie.)
I stuck a hose in and got out LOTS of crud from the sacrificial anode (Now I know what 'sacrificial' means).
Bottom line, washing out the hot water tank with a hose is VERY important.
