How To Prime A Water Well Pump. How to prime a well pump Next, turn that outside supply line back on and you will have supplied the pump with the necessary water to keep it primed.
In an emergency, you may have to use pond or stream water, but the water may contain sediments that could harm the pump. Partially plug the hole and run the pump until the air bubbles cease. Repeat the filling and running actions until water leaks out of the pump instead of air bubbles, then fully insert the prime plug into the pump.
Inspect the bolts, pulleys, belts and safety guards of the water pump while at it as well.
A well pump needs to be primed in order to create the internal pressure necessary to draw water from your well or other water source and pump it to where you need it to go. Move the funnel to the other priming plug location in the suction pipe, if applicable. You will know everything is working correctly if the water starts to drain at a steady rate. Ensure that you use clean water for this process.
