How to Prepare a Deep Well Pump

Quck answer

To prime a deep well pump, follow these steps:

1. Shut off the power to the pump.

2. Remove the cap from the priming port on the pump.

3. Fill a bucket with water and pour it into the priming port until it is full.

4. Replace the cap on the priming port.

5. Turn on the power to the pump.

6. Open a faucet or valve connected to the pump to release any air trapped in the system.

7. Wait for the pump to build pressure and start pumping water.

8. Monitor the pump and system for any leaks or issues.

9. If the pump does not start pumping water, repeat the priming process.


Deep well pumps are responsible for moving water in well systems. These pumps typically combine the features of centrifugal pumps and injector pumps to facilitate water movement. However, in order for a deep well pump to function properly, it must be properly primed. Priming a deep well pump involves filling the casing and piping system with water to ensure efficient water movement. Deep well pumps are equipped with a priming hole, which is covered by a prime plug, making the priming process easier.

Step 1

Begin by removing the rubber or plastic prime plug from the top of the pump. Then, connect a water hose to the exposed hole on the pump’s top side.

Step 2

Proceed to run water through the water hose and into the pump casing. Allow the water to flow until it starts to overflow from the casing, indicating that the casing is filled with water.

Step 3

Once the casing is filled, detach the water hose from the pump. Partially insert the prime plug into the hole on top of the pump. Turn on the pump system and continue running it until no air bubbles are visible at the bottom of the plug.

Step 4

Remove the plug and fill the casing with water again. Partially insert the plug into the hole and run the pump until there are no more air bubbles. Repeat these steps of filling and running the pump until water leaks out instead of air bubbles. Finally, fully insert the prime plug into the pump.
