How to Install a Shallow Well Jet Pump

Many homes, especially in rural areas, have wells as their water source. The wells can be deep or shallow depending on the water table. Jet pumps are used to obtain water from shallow wells. The jet pump uses an electric motor, an impeller, and a jet assembly to draw water from the well. The pump is above ground allowing for easy maintenance.

Tools:

• The jet pump


• A suction and a discharge pipe


• Pressure tank and switch


• Pressure control valve for the discharge pipe


• Foot valve


• Cross–tee


• Pipe and adjustable wrenches


• Water pressure gauge


• Sealant

Instructions:

1. Take the depth measurements of the well.


2. Determine the voltage you will require for your pump and get the best pump for you requirements.


3. Measure the suction line and install the foot valve at the end of the line, five feet from the bottom of the well. Use the thread sealant to connect the pipe to the pump.


4. Install the cross-tee on the pump discharge and connect the pressure tank using threaded pipe and sealant. Avoid using too much sealant as this can lead to clogging.


5. Insert a ball valve, pipe reducer and a cap on the opposite side of the cross-tee, to act as the connection for priming the pump.


6. Install the pressure gauge after you have completed the priming. The gauge helps in monitoring the pump pressure.


7. Install a ball or a flow control valve to control discharge pressure. This is important to control pressure during periods of high usage of water.


8. Place the pressure switch downstream from the pressure tank tee and set it. Connect the pressure switch to the electric supply. Ensure you follow the instructions for the right electrical connections.


9. Open the pipe cap and fill the casing with water, then open a faucet on the plumbing to allow air to escape as you prim the pump.


10. Repeat the priming process until you get water flowing. The pump should be able to pull water from the well if it has been properly installed.


11. Disconnect the electric supply before wiring the pump. Check for leaks if the pump is not pulling water from the well.
