I leave my 3121 hooked up in a RV park and split time over the winter with my home and RV. I don't winterize but leave the heater on and set the thermostat at the lowest point which is 40 degrees. I shut the water off and drain the hose but not the RV. Never have any problems and all I need to do is hook the water back up when I go back.
