Winterize go Question? Anyone put Antifreeze in your Hot Water Heater

My friend always does it but I drained mine and there is still some water in the bottom.

Yikes, NO...no need to but make sure you have the bypass lines switched for winterization. (The small amount in the bottom of the tank will freeze but it'll be fine...the problem is when water freezes and expands but there's no room to expand so breaks whatever is holding it....I've seen it break copper pipes so our PVC pipes don't stand a chance.)

I feel like I've read that there can be a chemical reaction between the water heater interior and RV antifreeze. Don't know if I'm making that up, if I read it from a credible source, or anything in between.

I think OldCoot fashioned up an attachment for his shop vac to such that last but and any anode debris out. But generally speaking, as long as you dump it out- the water has somewhere to expand to when it freezes and it's not an issue.

Hot water tank

Leave the drain plug out over the winter. that allows for the extra water to exit.

Thats exactly why they put bypass valves in place....so you don't fill your hot water tank with 6 gal or more of antifreeze....to do so would be a total waste, and you may not be able to drain the antifreeze out as easily as you can flush it out of your lines.

I drained it and left anode out no antifreeze but tiny water in the bottom can evaporate before winter we are good.

If you are going to leave the rod out stuff a paper towel in the hole to keep bugs from crawling inside for the winter.
