I’ve been draining RV’s for winter on and off for 40 some years and have been fortunate to never have had any winter damage from lines freezing. I live in Manitoba which, with the possible exception of Siberia, is as cold as it gets anywhere.
After I drain my tanks I remove the spout from the kitchen sink and hook up a small, tankless,low-pressure oilless compressor. I stick a hose which just fits nicely into the spout hole and let the compressor run. Opening up the kitchen faucets one at a time I blow the air out of each hot and cold line by opening the bathroom, shower, and toilet valves. I just let it run as long as it takes to remove any trace of moisture from the lines.
Lastly I add a cup or so of plumbing antifreeze to each trap (don’t forget the one on the bathroom floor). and to the toilet. Leaving a quart or so in the holding tank is also a good idea.
A couple of handy things I learned off the web: Give a shot of air to the outside city water connection and lower the coach when draining the holding tank.
Years back I tried adding antifreeze to the water tank but it seemed to take forever to get the stuff out in the spring – and I have found that if you ensure that the last vestige of water is out of the system it’s not necessary.
Works for me
