Open both valves with the pump off then suck on the winterizing hose until it’s full of water. Then close the tank full valve. Turn on the pump and blow as hard as you can into the full winterizing tube to force water toward the pump.

Our camper has a 2-way valve but I find I can do something similar by putting the valve halfway between to suck water into the winterizing tube. No bucket needed that way.
