Deep Well Jet Pump Installation

Jet pumps which are primarily used for shallow wells less than 25 feet deep should be placed in a well housing and then mounted above the well in a separate well house or other structure.

Deep well jet pump installation.

Deep well jet pumps use two lines one for pulling the water and one for pushing the. If replacing the switch we recommend using one with a 30 5 psi setting. Unlike submersible pumps they must be primed with water before they can draw the water. Run pipe between the pump outlet and tank inlet connecting it with appropriate fittings.

Do not reduce the sizes of pipe. Deep well jet systems are used when the water depth is between 20 and 80. The shallow well jet pumps draw water from one line situated in wells no deeper than a maximum of 25 feet deep. The tank should also be located as close to the pump as possible to avoid excessive pressure and friction losses.

Convertible jet pumps like the red lion rjc 100 shown at above left that can be swapped between a shallow well typically from 25 ft one line jet pump to a deep well two line jet pump are typically capable of lifting in the 2 line jet pump conversion from a depth of about 90 feet. Jet pumps usually come with a 30 50 pressure switch factory installed on the pump. Deep well jet pumps use both the suction at the jet to bring water into the system and pressure applied by the impeller to lift the water. A jet pump performs best when installed close to the well because suction lift and friction losses are kept to a minimum.

A foot valve must be used if the ejector or jet does not have a built in check valve. Screw an adapter to the threaded pump outlet and tighten it with a wrench. Step 2 deep well pumps are always installed with the ejectors or jet attached to the bottom of the suction pipe in the well. For deep well installation the drive line is 1.
