After draining all the water from the tc,including removing the plug from the hot water heater, what else? The anode attached to the plug is half eroded away, I guess it should be replaced? Should the plug be left out so the inside of the tank might dry out. Should I blast warm air in there to try and dry it out? I'm trying to prevent premature electrolysis from pitting the aluminum. Any thoughts?

Nothing else needed. I leave my anode rod out for a while so the remaining water evaporates.

I cover mine so bugs and stuff cant get in it. Make sure its bypassed, and some rinse them out to get the gunk out of them.

Atwood vs Suburban

"I'm trying to prevent premature electrolysis from pitting the aluminum. Any thoughts?'

Aluminum tanks don't use anode rods.

Bypass Water Heater so any anti-freeze pumped thru plumbing lines does not go into water heater
Then remove Anode Rod (SUBURBAN BRAND ONLY---steel tank)
Drain water heater
Then reinstall anode rod to protect threads from rusting and from spiders/bugs from setting up house


Anode rod 'half' gone......replace with new one next season


Is it time for your medication or mine?

Check your water heater too
Not sure why you would need a hot water heater?

I disconnect one pos/negative connections and tape them up individually ... just to make sure that I/wife don’t accidentally turn it on with no water.

If you have an anode, replace it.

I made a tank rinser out off flexible tubing and rise the tank out when I winterize. There is a fair amount of mineral build up that will come out if you never rinsed the tank before. There is also water in the bottom of the tank that won't drain out that I siphon out with a small plastic tube then put the plug in and blow the entire water system out with compressed air. If you have an electric element in the tank follow Jim's advice. I forgot to do this one year and my electric element burned in half. Half is still in the bottom of my tank.

Instead of removing wiring from element just open the 120VAC Circuit Breaker
Or if an Atwood (2004 to present) pull the 2A fuse on circuit board
