To prime a bore pump, you typically access its priming port, ensure seals are intact, fill the pump casing with water, close the port, turn on the pump, and verify operation.
Properly priming a bore pump (also known as a submersible well pump when referring to the type installed in a bore, though priming usually applies to surface pumps connected to bores or wells, or the column pipe itself) is crucial for its function. Priming removes air from the pump casing and intake line, allowing the pump to create the necessary suction to draw water from the bore. Without priming, the pump will run dry, which can cause damage.
Here's a breakdown of the key steps involved, drawing from the provided reference:
Steps to Prime Your Water Pump
Following these steps will help ensure your pump is ready to draw water efficiently and safely.
1. Access the Priming Port
First, you need to locate the priming port on your water pump. This is usually a threaded plug or cap located on the top of the pump casing.
2. Seal Check
Before adding water, it's important to check the pump's gaskets and seals. Ensure they are in good condition and properly seated. Damaged or worn seals can cause air leaks, preventing the pump from holding prime.
3. Fill With Water
Carefully fill the pump casing completely with water. You may need a funnel or a hose to do this. Fill it until the water level reaches the top of the priming port. This displaces any air inside the pump.
4. Close the Priming Port
Once the pump casing is full, securely close the priming port by replacing and tightening the plug or cap. Ensure it is sealed tightly to prevent air from entering.
5. Turn On the Pump
With the priming port closed, turn on the pump. The pump should now be able to create suction and draw water from the bore or well.
6. Check for Proper Operation
After turning on the pump, observe its operation. Water should start flowing shortly. Listen for the pump running smoothly and check for a steady stream of water. If water doesn't flow after a minute or two, or if the pump sounds like it's still running dry, you may need to repeat the priming process.
Practical Tips:
- Keep a bucket and funnel handy for filling.
- If your pump is connected to a long pipe run, it might take a little longer for water to reach the surface.
- Some pumps have a check valve on the suction line, which helps prevent water from draining back and losing prime. Ensure this is functioning correctly.
By following these steps, you can effectively prime your bore pump and restore its ability to draw water from the source.
