Winterizing

Aloha All, Second time winterizing this winter. First time I used RV anti freeze. Second time I drained and blew out the water lines. I used a cheapo 12 volt tire inflator, the kind you plug into cigarette lighter and 50 feet of garden hose. Attached garden hose to city water fitting on side of T@b and attached other end to air pump using a RV blowout plug. With all trailer faucets CLOSED I turned on the airpump and pressurized hose to 45-50psi .  Opened faucets one at a time, pressurizing hose between opening of faucets, and blew water from all lines. Garden hose acted as a pressure accumulator and supplied ample air to blow out the lines. A lot less work and no issue  flushing out anti freeze.
