VEVOR Utility Pump, 1 HP, 4000 GPH High Flow, 31 ft Head, Sump Pump Submersible Water Pump Portable Utility Pump with 10 ft Long Power Cord for Draining Water from Swimming Pool Garden Pond Basement
If I were to use this to pump water up from one tank into another tank uphill from the source, would the water backflow through this pump when turned off or would it hold the water and prevent backflow?
