This Cover Drain Pump Siphon and Hose is a practical way to quickly remove the water from your above-ground pool winter cover. Operating without electricity, it lets you drain the accumulated moisture on the cover by using the squeeze-operated bulb to prime the pump and begin the flow of water. Then it will automatically shut off when the cover is drained. This pool cover siphon pump is handy for maintaining your pool in the winter months until it’s time for swimming and splashing fun. The pack comes with the drain, pump, siphon and 13′ of hose.
