Jet Pumps Frequently Asked Questions

A pump operated in a well less than 50 feet deep which can draw water up to a further 20-25 feet is considered to be shallow well pump. This type of pump is also known as a shallow well jet pump.

A shallow well pump should be installed at a height of 25 feet above the water level.

  1. A foot valve is installed at the bottom of the pipe work.
  2. Lower the pipe into the well until the foot valve is 5 feet below the lowest anticipated water level, ensuring that it is atleast a foot and a half above the bottom of the well so as to avoid sand or sediment from being drawn into the pump during operation.
  3. A well seal is then fitted to avoid surface water and other contaminants from entering the well.
  4. The pump is then mounted to an adequately flat surface and the outlet of the pump is plumbed to any further pipework for delivery of water as required. Any horizontal sections must have a slight upward slope away from the pump outlet to avoid air locks in the pipelines.

For a more detailed description, please refer to the relevant installation and instruction manuals.

  1. Use a plumber's wrench to take off the inlet and outlet ports on the old pump.
  2. Unscrew the wires going to the pressure switch on the old pump with a screwdriver.
    Remove any old mounting bolts and lift off the old pump.
  3. When replacing well pumps, apply Teflon piping tape on the threads of the outlet and inlet pipes, wrapping tape around each pipe at least 4-5 times to ensure a proper sealing to prevent water leaks.
    Install the new pump, following the instructions on the installation guides provided.
  4. Screw the pipe from the well, to the inlet pipe on the well pump with a plumber's wrench.
  5. Screw the pipe that delivers water to the outlet pipe on the jet pump with a plumber's wrench.
  6. Connect the wires to the appropriate terminals on the pressure switch of the new pump.
  7. Tighten the wires to the electrical terminal with a screwdriver.
  8. Check that the pump motor is wired for the same voltage as what is being supplied from the circuit breaker.
  9. If the voltage is not the same, rewire the pump motor to the appropriate voltage configuration as per the manufacturer included instructions.
  10. Prime the pump. Jet pumps need to be primed before use. Do this by filling the pump with water through the outlet pipe coming out of the top of the pump or an available access hole that may be located on the pump. Pour in water until the pump is full.
  11. Turn the circuit breaker back on and test your new pump

Always follow instructions from your installation and user guides.

Multiple parameters are required to determine the capacity of the desired shallow well pump. Preliminary parameters are water discharge or flow requirements which needs to be calculated based on the household need (number of family members, various home appliances) or consumption which deals with water such as washing machine and dish washer and the distance to transport the water. For accurate selection of the appropriate capacity shallow well pump, please refer our product selector.

A shallow well pump may stop operation properly due to a number of reasons. You will have to go through a series of checks in order to arrive at the most likely cause. In some cases, you may be able to do this without a certified technician. Should you need to set up a service call with a Taro technician, please follow this link.

For more information on the checks you will need to do to find the problem with your pump, please refer to the troubleshooting guide.

Yes. A pressure tank is necessary if you want water to be pumped at a consistent flow and pressure through showers, faucets, washing machines and other appliances.

Low water pressure may be because of low water volume at the source, clogged pipes, clogged well casing from well sediment, sand, minerals or improper positioning or installation of the pump. Or your pump may be grounded. Check the pressure reading on the gauge, if it is less than the prescribed limit then check the pump breaker in the electrical box to see if it has tripped. You may also book a visit from a service technician.

You could also refer our troubleshooting guide for most common problems that you may be able to resolve by yourself.

The pump and pipe system are filled with water. The water in the pump impeller is thrown outwards by the vanes of the spinning impeller. As the vanes throw the water out, a vacuum is created at the eye of the impeller, and more water is drawn in to replace that which was thrown out. Some of the water discharged by the impeller passes out of the pump and into the pressure tank. The rest is recirculated through the drive line to the injector in the well.



In the injector, the nozzle and the venturi create a vacuum. This vacuum draws water from the well, through the foot valve. As the water passes through the venturi tube into the suction line, the pressure is increased sufficiently to force the water back to the pump impeller.

Fill the pump with water through the outlet pipe coming out of the top of the pump or an available access hole that may be located on the pump. Pour in water until the pump is full then run the pump. The vapour present in the pipeline will be sent out then the pump will be primed.
