Temps projected to get into the 20s this weekend but I don't want to wet winterize yet due to planned trips this month and in December.
I used my blow out plug and air compressor. After blowing out all of the lines I left the compressor connected at approx 40 PSI. With the Ice maker on it continued to make about 3 trays of cubes and I turned it off last night with the a load of cubes still freezing. This morning I reconnected the compressor to the city water connection and turned on the the ice maker. After the load of cubes were dumped the ice maker water supply blew in air from the compressor with little or no water. I will leave the compressor connected for another cycle or two to make sure all of the water is blown out of the ice maker lines and solenoid and then disconnect.
The blow out plug I use is
Camco Blowout Plug with Quick Connect-36143 - The Home Depot
