Dewinterizing systems

Roadtrek recommended pouring antifreeze into the water holding tank then pumping it through the system. I don't know how much is in the tank now but I think I put more than a gallon in last fall.

I am sure there is a better system to do it but with arthritic hands, it was the easiest way I could do it last year.

I know I can flush it out and use baking soda to improve the taste. I was wondering where I could flush the water with the antifreeze in it.

Assuming there is little anti freeze in the fresh water tank, you should be able to just dilute it with water and flush it out.

I don't see why you have anti freeze in the tank; normally (AFAIK) you only put antifreeze in the plumbing lines (pumped in from a separate line source put in the anti freeze bottle that bypasses the source line from the water tank). That is what I do anyway.

How much antifreeze is there in your tanks? Normally there should be around a quart or less. I just leave it and dump at a dump station or campsite when I dump for the first time after the winter.

Also remember that RV antifreeze is non-toxic and doesn't need special handling like automobile antifreeze does.
