Review on Hotop Winterize Blowout Connecting Winterizing by James Cruz

First I drained all the fresh water from my tank. I set the air compressor to 30psi, closed the valve on this unit, connected it to the city water line, opened the fresh water drain valve and SLIGHTLY opened the valve on this unit and waited. As soon as the water was being forced out by the air, I carefully opened the valve even further. When it stopped I closed the air valve and the fresh water drain valve. Then I opened all the pipes (sink, kitchen sink), slowly opening the air valve until nothing but air came out of the sink pipes. I also walked over and stepped on the toilet flush valve to drain the water. I closed the air valve. Disconnected it, and then opened all drain and drain cocks for an hour. We closed them all and winterized the plumbing. No antifreeze required!
