How to pump water from a deep well
Different sized wells require different types of water pumps. (wishing well image by Carol Wingert from

Pumping water from a deep well requires a deep well jet pump. Deep well pumps are cost efficient and require little maintenance after installation. They also can be used at a variety of depths. Before installing or purchasing a deep well pump, contact a pump supplier to determine the correct pump size for the required amount of water.

  1. 1

    Ensure that the well is clean, and that there is no sand or grit in the water supply.

  2. 2

    Attach the ejector or jet of the pump to the bottom of the suction pipe inside the well. If the ejector jet doesn't have a check valve, use a foot valve. Also, a tail pipe can be used underneath the ejector, with the foot valve mounted on the bottom of the tail pipe.

  3. 3

    Install the foot valve on the bottom of the ejector (or to the bottom of the tail pipe if you are using one). Connect the ejector to the quarter-inch pipe, and lower the assembly into the well. Keep adding pipe until the ejector is lowered to the desired depth. As you lower the assembly, fill the suction pipe with water.

  4. 4

    Fit the casing adaptor onto a piece of quarter-inch suction pipe by loosening the flange bolts on the adaptor. When the casing adaptor is installed, tighten the bolts. Fill the well adaptor with water--the well adaptor has two holes for two different sized pipes. Fill the adaptor so that both the one-inch and 1 ¼ inch holes are full of water.

  5. 5

    Mount the pump onto the well adaptor,so that the one-inch and 1 ¼ inch holes line up with the same holes on the adaptor.

  6. 6

    Pour water into the discharge of the pump housing (or the automatic regulator if your model of pump has one).

  7. 7

    Turn off the power to the pump, and check the motor to make sure the appropriate voltage is being used.

  8. 8

    Switch the regulator to maximum pressure, and start the pump. Water should begin discharging from the pump. The pressure will decrease as the flow increases. Keep opening up the regulator until you hear a change in the tone of the pump. Read the pressure on the gauge; this is your optimum operating pressure. Secure the pressure level by installing a jam nut on the regulator.

  9. 9

    Connect the discharge of the pump to the water tank using a length of galvanised or PVC pipe.
