[Richard and Rhonda]

It doesn't get as cold here in Texas, but it does get cold enough for water to freeze, so here is what I do.

First I made a little device that connects to a quick disconnect air fitting on one end, has a pressure regulator in the middle, and a male garden hose fitting on the other end. I set the pressure at thirty pounds, and hook that contraption to the water inlet. I use the compressed air from the bus for supply. I make two complete rounds through the coach running water from each outlet until very little water is blown out. Make sure you do the frig and washer too.

Then I pour the pink antifreeze in sinks, tub, and potty to keep the traps from freezing.

I use the manual disconnect switch on the house batteries.

Takes about 15 minutes.
