How to Prime a Submersible Well Pump A Step-by-Step Guide
Priming a submersible well pump is an essential maintenance task that ensures your water supply system operates efficiently. While submersible pumps are designed to be submerged underwater and typically deal with their own priming, situations may arise where the pump requires manual priming due to air locks or other issues. In this article, we will outline the steps to prime a submersible well pump effectively.
Step 1 Gather Necessary Tools and Materials
Before you begin, ensure you have the right tools and materials on hand. You will need - A bucket or container - A garden hose - Adjustable wrenches - Teflon tape or pipe joint compound (for sealing connections) - Screwdriver - A submersible well pump installation manual (if available)
Step 2 Turn Off Power to the Pump
Safety should be your primary concern. Before performing any work on the well pump, turn off the power supply. Locate the electrical control box or disconnect switch and turn it off to prevent accidental starts while you are working.
Step 3 Remove the Pump from the Well
If you suspect that the pump needs to be primed, you may need to remove it from the well. This step can be labor-intensive, so a second person may be helpful. Use a wrench to disconnect the pump from the well head and carefully lift it out. Ensure not to damage any wiring during this process.
Step 4 Inspect the Pump
Once the pump is out of the well, inspect it for visible signs of damage, such as cracks or corrosion. Check the inlet screen to ensure it is free of debris, as blockages can affect the pump's ability to draw water.
Step 5 Connect the Garden Hose
Find the discharge port on the pump and attach a garden hose to it. Make sure to secure the connection tightly to prevent water leaks. If necessary, use Teflon tape to seal the threads. The other end of the hose should be placed in the bucket or another container to catch the water being pumped.
Step 6 Fill the Pump with Water
Before you attempt to start the pump, fill the pump body with water. You can do this by pouring water directly into the inlet opening or through the hose until no more air bubbles escape. This step is crucial as it helps eliminate air pockets that can prevent the pump from starting effectively.
Step 7 Restore Power and Start the Pump
After ensuring the pump is filled with water and connected properly, restore the power supply to the pump. Switch on the pump and monitor its performance. Watch for any unusual noises or vibrations, which may indicate issues within the pump itself. If the pump does not start after several attempts, you may need to repeat the priming process.
Step 8 Monitor the Water Flow
Once the pump is operational, check the water flow through the hose. Ensure the pump is drawing water steadily without any interruptions. If the water flow is weak or inconsistent, you may have to troubleshoot further to identify the cause.
Conclusion
Priming a submersible well pump is a straightforward process if approached methodically. Regular maintenance and inspections can prevent problems and ensure a reliable water supply. Always consult the manufacturer's manual for specific instructions related to your model. By following these steps, you can ensure your submersible well pump functions optimally, providing you with a steady source of water.
