Review on Hotop Winterize Blowout Connecting Winterizing by Justin Ritter

This simple garden hose adapter will winterize my RV without antifreeze and save water without having to flush the lines after using antifreeze. I set the outlet pressure on my air compressor to 40psi; then I screw this adapter into the water pipe; then I connect an air hose and slowly open the valve to allow the compressed air to push all the water out of the pipes; Open all faucets and drains at low point and cycle back and forth with the appropriate water valves to drain all relevant lines.
