Winterizing without anti-freeze - Event Date: 28 Dec 2012

Originally posted by Raymondo Here's a little trick for voiding all the potable water out of the lines in preparation for winter without the use of anti-freeze. Air. I built a device made using standard air tool fittings and a small compressor to blow out the lines (slowly) without the fear of over pressurizing and blowing out a tap or seal. I first removed the threaded drain plug from the HWT and let drain out by gravity. Next open all water taps to vent. Attach blow-out device to R-Pod city pressure connection outside, with shutoff valve closed. Connect air line to compressor, set pressure to about 20 lbs, and turn it on. Slowly turn ball valve (yellow handle) until air flows into the water connection forcing water through the interior lines, and out through the HWT drain. Note: this does not drain your fresh water tank. You will have to pump that dry into your grey water tank, and then drain.
