Efficient Draining: Sump pump with 1.2 HP energy-saving motor, improves motor efficiency and reduces energy costs. Removes water down to 2 inch of the surface. Making draining a breeze Auto Manual Mode: Designed with a float, this pool draining pump can work manually or automatically according to the actual need. Before using, fully submerge the pump in water at an inclined angle for 20-30 seconds to remove excess air Water Transfer Pump: With the filter screen, you can freely switch draining clean or dirty water.
