Priming the Pool Pump 
is needed in the beginning of the season, or after cleaning the pump basket. Some pumps need to be primed after they sit for a period of time. Older or undersized pumps may struggle with this.

Follow the instructions below to prime your pool pump.

To prime the pump:

  1. Turn off the pump. Make sure heater is off also if you have one.
  2. Remove the pump lid.
  3. Take garden hose or bucket and fill pot entirely with water.
  4. Make sure your pump lid has an o-ring in place, and that it is in good condition and lubricated. DO NOT use petroleum-based products. Replace the lid on the pump pot and secure it, hand tight.
  5. Turn on the pump and watch to make sure water starts to flow in the pot from the plumbing lines. If water does not start to flow after about a minute, shut off and repeat steps 1 – 5 again. Some pumps are hard to prime, especially if the pool sits downhill from the equipment pad. If there is a shut off valve before the pump, make sure this is in the open position.
  6. If there are multiple valves in-front of the pump, like “skimmer” and “main drain”, “spa drain” etc. close all but the closest item to the filter system. Priming is the removal of air from the plumbing, so it’s easier to remove air from 1 pipe rather than 2 or 3 pipes. Once primed, then you can sloooowly, open the valves, and allow the pump to sloooowly suck the air from the pipes without allowing it to loose prime. If you do, close all but the 1 valve and start over.
  7. Once the strainer pot fills completely and the pressure gauge on the filter builds to a normal reading, you have a prime.
  8. If you cannot get a prime, Make sure there is ample water in the pool.
  9. Make sure all fittings and unions in front of the pump are tight and not cracked.
  10. Make sure skimmer baskets are empty
  11. Make sure the skimmer weir (flapper) is not stuck in the up position.
