Used info from forum and winterized today. Anybody else have to remove fitting on water pump to safely remove water tank hose from barb on pump? I'm sure it would have broke the barbed elbow if I kept pulling while it was attached to the pump. Attached longer hose to the barb and hooked it back on the pump and used two gallons of antifreeze in lines. Seemed rather simple. We've only had a few nights in the high 20's and I had a ceramic heater running but it will get colder soon and I needed to winterize.
