I blow out my class A water lines every fall. You can not blow out all the cavities in the water pump, so I pump a touch of antifreeze in the pump. Of course you have to drain the water heater and take the necessary precautions for the ice maker. Undo the ice maker water line from the valve to drain it. Remove line feeding the ice maker valve to blow out the water line.
