Spring is here and so is camping season. I spent my first night in the RV this year this past Saturday. I don't have a way to dewinterize at my house so I went to a nearby KOA and got a full hookup site. I did a video of the steps I took to dewinterize if anyone is interested. I used city water to flush the antifreeze from my lines before I sanitized the fresh tank and ran that water through the lines over night.
I have to thank the good folks here with helping me out. The anode rod did not seat all the way in and I thought it was supposed to. I posted a question about it on the plumbing forum here and had answers in no time. So I was able to sanitize the hot water heater and had no leaks.
Now I can't wait to get more nights on the road.
