A deep well jet pump has a venturi (jet) and a check valve (foot valve) located in the well to enable the pump to pump water >32 ft. The jet and foot valve are located 10 to 20 ft below the minimum water level in the well. One pipe mounted to the impeller housing of the pump, drives water down into the jet body located in the well. A second pipe connects the output side of the jet body back to the pump. Like shallow-well systems, a jet pump in a deep-well system needs to be primed to operate. The foot valve at the bottom of the well piping prevents water from draining from the pipes and pump.
