Submersible pumps are essential for moving water in wells, basements, and irrigation systems. However, if your pump isn’t primed correctly, it won’t function efficiently—or at all. Priming ensures there’s enough water in the pump to create the necessary pressure for operation.

In this guide, we’ll walk you through how to prime a submersible pump properly to keep it running smoothly.

Why Priming a Submersible Pump is Important

Priming removes air from the pump and suction line, allowing water to flow continuously. Without proper priming, your pump may:

● Overheat due to dry running

● Lose pressure and fail to move water

● Suffer damage to internal components

While some submersible pumps are self-priming, others require manual priming. Always check your pump’s manual before starting.

How to Prime a Submersible Pump

Tools You’ll Need:

● Water source (hose or bucket)

● Wrench or pliers

● Teflon tape (for sealing connections)

● A funnel (optional)

Step 1: Turn Off the Power

Before working on the pump, disconnect it from the power source to prevent electrical hazards.

Step 2: Check for Leaks

Inspect the pump, pipes, and fittings for leaks. Tighten any loose connections and use Teflon tape on threaded joints if needed.

Step 3: Fill the Pump and Suction Line with Water

1.If your pump has a priming port, open it and pour water until the pump and suction line are full.

2.If there’s no priming port, disconnect the discharge pipe and fill it with water using a funnel or hose.

Step 4: Reassemble and Secure Connections

Once the pump is filled, reattach any disconnected pipes and ensure all fittings are tight.

Step 5: Turn the Pump On

Restore power and switch on the pump. Listen for unusual noises, which could indicate air still trapped in the system.

Step 6: Monitor Water Flow

Check the discharge line for steady water flow. If the pump struggles or sputters, turn it off and repeat the priming process.

Troubleshooting Common Priming Issues

● Pump Won’t Prime? Check for air leaks in the suction line or a faulty check valve.

● Loss of Prime After Running? The foot valve may be leaking, allowing water to drain back.

● Air in the System? Ensure all connections are airtight and the water source is sufficient.

Final Thoughts

Priming your submersible pump correctly ensures longevity and peak performance. Regular maintenance, including checking seals and valves, will help prevent priming issues in the future.
