How to Prime your Pump: A Step-by-Step Guide

If you’ve turned off your water pump over the winter months, it’s possible that it has lost prime. To get your water pump working again, it will need to be re-primed. We will show you how to prime your pump. Priming the pump involves refilling water back into the system and forcing it through the pump and suction pipe, creating the conditions needed to start pumping again. Follow these simple steps to prime your water pump and get it running smoothly.

  • Turn off the power Ensure the pump is not plugged in while you’re working on it. Check the breaker panel to turn off the electrical power and double-check the pump’s base for any power connections.
  • Access the pump system Find the plumbing fixture closest to your water tank for access. On above ground well pumps, this should be a priming port or discharge pipe connection on the top of the pump.
  • Inspect for damage Thoroughly inspect the pump and piping for any cracks or damage. Be sure to check drain plugs, fittings, and valves. Manually test the valves and ensure all hardware like nuts, bolts, belts, and pulleys are secure.
  • Test the hose Before use, flush the hose with clean water. Be cautious, as garden hoses may contain lead, so avoid drinking from them. If using a well pump, make sure the water is properly filtered before and after it flows through the hose.
  • Open the relief valves To prevent pressure from building up, open the relief valves and monitor the pressure gauge.
  • Attach the hose Connect the hose to the nearest water tank for a standard water pump
  • Turn on the water and wait Fill water into the pump body and suction pipe slowly, to allow for air to escape as the priming water fills up to the top of the pump body. Once water flows from the opposite end of the hose, turn off the water.
  • Check for leaks We recommend letting the filled pump sit for 10 minutes, fully filled before sealing it up. This is to test for leaks – such as a leaking foot valve, check valve, or pipe fittings. If water level continuously lowers in the pump body while sitting idle, it likely means there is a leak in the pump or plumbing.
  • Restore power Once you have confirmed that the pump is holding prime while turned off…Turn the pump on and let it run for a minute. If you opened any relief valves, wait until water starts flowing before closing them. If the pump stops naturally, it’s successfully primed. If not, repeat the process.
