Re: RV Anti freeze for drains?
I used it for a lot of years in my current house living alone, traveling a lot, no heat on at all when I was gone. Also used it for several years in a 2nd uninhabited house I used only for storage. The more diluted the less the protection. In other words you don't take a full toilet tank and pour some in. In a toilet you shut off the supply, flush it to drain the tank, plunge the bowl, then I put a cup in tank and bowl. One cup down each drain/trap. Shut off the well pump and drain all the fresh water supply lines.
