Make sure your fresh water tank is full, disconnect the water hose and use your pump. That is the best way to eliminate the worry. Then, just fill your tank each day, or as often as needed. Also, only connect your drain hose when draining, otherwise if a valve is leaking, you could freeze up the drain hose.
