Winterized Water Heater

2014 GulfStream Streamlite 28Rbb. So I live in MI and obviously it has already froze and actually been in the 40/50's the last few days so Thawed also. My question is when I went through and drained the water for winter, I opened all the valves ran the pump till it was spitting air. Opened the low point plugs underneath and also the freshwater plug, poured A/F down all drains and toilet.

What Im concerned about is the Water Heater, I only drained it by opening the relief valve while pumping the water out until it was also just spitting air. My problem was that when I tried to get the large Bolt from the bottom of the Water heater panel on the outside, it was so rusted that I actually broke my channel locks in half. I was over at my storage place over the weekend and popped open the relief valve again and some water trickled out so I let it until nothing. My question is at this point is there something I should do or has the damage (or hopefully lack there of) been done?
  • If the bolt you referred to is the drain (for Atwood) or anode (if Suburban) it should have a hex head about size 15/16 (as I remember) and the easiest way to get it out is with a socket. If yours is rusted it may be useful to spray it with WD-40 and, even better, use a hammer drill on the socket.
    However, since it is winter now I would suggest removing the relief valve and pour 1/2 bottle of A/F thru the hole. There may not be enough water in the heater to be a problem but this is a little insurance.
    Next year, however, remove the drain/anode plug to get all the water and A/F out AND use a Tank Saver sprayer to flush out more of the crud.
  • Yeah that is on my list of things to do, I really just didnt want to run into an issue of braking the bolt somehow and really being screwed. Anyone on here off hand no the size Socket that would be? I probably have one between my garage and my dads.
  • If it was me, I would get that correct six point socket that fits that bolt on the bottom and try to persuade it out. A 2014 shouldn't be that far gone that the bolt is seized. But the right tool for the job is very important so you don't break, what isn't broken.
