If you have a winterize setting, to pump antifreeze from a bottle, you can use that to pump water from a container into the tank. It's not the fastest operation ever. Just set the valves for winterization and open the fill valve and turn on the pump.
Seems to me if this were correct, a person would have to fill the water tank with antifreeze, in the process of winterizing.
There is normally a check valve on the tank side of the pump to keep water/antifreeze from flowing backwards into the tank.
