I have an off grid cabin in Northern NH in the mountains that i visit a lot, but leave unheated. I redesigned the plumbing several years ago to plumb a drain back valve and a small compressor to blow out the lines when I left in winter months, Although this ok, small amount residual water remains, especially in the on demand water heater. For years I had jury rigged pump and RV antifreeze setup, that was messy and inconvenient. I ran across this integrated pump/reservoir product that have been using for about 4 years, and it has saved me so much time and aggravation: The Clozer (https://www.theclozer.ca/).
It’s a little expensive for a pump with a pressure switch, but this thing has saved me so much time closing down my cabin on cold winter weekends, that I thought I’d recommend it to others who had the same use case.
