The pump uses suction and pressure to circulate the pool water and is part of the filtration system.
Often heaters and chlorinators are plumbed into the return line, so the water can be heated and sanitised on its way back to the pool.
An impeller at the back of the pump housing spins and creates suction, which draws water into the front of the pump.
As the impeller rotates, it pushes the water out through a discharge port, usually located at the top of the pump.
When the pump is operating, water before the impeller, which includes the chamber under the pump lid, is under suction. After passing through the impeller the water is then under pressure.
The pump needs to be full of water and without air, so it can create a suction to operate.
Verify that the water level in the pool is high enough for the pump to operate.
Make sure the pump is completed powered off, either at the chlorinator, controller, or power switch.
Have a bucket full of water or garden hose ready for adding water to the pump.
Removing the pump lid requires rotating the lid anti-clockwise or unscrewing and releasing lid fittings or clips.
Using the bucket or the garden hose, fill the pump chamber with water until it reaches the top.
Quickly replace the lid, ensuring the o-ring is properly seated to prevent any air leaks.
Turn on the pump, it should begin to prime and draw in water from the pool.
If the pump doesn’t prime within a minute or two, repeat steps 5 & 6.
Watch the pump for a few minutes to monitor water flow and that the pump continues to circulate water.
Inspect in and around connections at the pump for any water leaks.
Turn your system back to running on “Auto” either at the chlorinator, controller or timer.
Several different factors can contribute to your pool pump failing to prime.
Low Water Level
Check that the pool water level is high enough for the pump to operate.
Resolve: The water level should be maintained at approximately halfway up the skimmer opening.
This may vary for each pool, but enough water is required so that the pump doesn’t draw in air while operating.
If the water level is too low, add water until it reaches the correct level.
Air Leaks
Air leaks in the suction line, pump lid, pump fittings or valves before the pump can prevent the pump from priming.
Suction cleaners that connect to the skimmer box through vacuum plates can also cause air leaks.
Pumps that are considerably higher than the pool water level can lose water in the suction pipe, with even a small air leak at the pump, or in return lines.
Resolve: Use the smoke from burning incense to check for leaks above the ground in the suction line, pump lid, pump fittings or valves before the pump. The smoke from the incense will get drawn in if there is an air leak. If you identify an issue that you can’t solve yourself, consult with a pool professional to solve the problem.
To check if there is a suction cleaner air leak, remove the cleaner from the pool skimmer and try prime the pump. If the pump primes as it should, consult with a pool professional to help resolve the suction cleaner problem.
A pump considerably higher than the pool water level can be challenging to prime. If multiple attempts to prime are unsuccessful, or if the pump continues to lose prime after being turned off, consult with a pool professional to solve the issue. Installing a non-return valve before the pump can make future priming much easier.
If there are cracks that are in suction pipe-work under the ground, consult with a pool leak detection specialist to identify and resolve.
Valve Positioning
Incorrect valve positions, such as partly closed on the suction or return lines can restrict water flow and affect priming.
Resolve: Move suction or return valves to their correct position.
If you are unsure, consult with a pool professional and take photographs while they are attending for future reference.
Suction Pipe Air Lock
Air trapped in the suction pipe, especially after repairs or maintenance can prevent the pump from priming.
Resolve: Try prime the pump and if after multiple attempts you’re are still unsuccessful, consult with a pool professional.
Clogged Skimmer or Pump Baskets
Skimmer or pump baskets that are full of leaves and debris can restrict water flow.
Resolve: Empty skimmer or pump baskets and include more regular checking and emptying in your pool maintenance routine.
Clogged or Dirty Filter
Debris trapped inside a media filter or cartridge filter can affect priming of the pump.
Resolve: For media filters backwash for 30 seconds longer than it takes for the viewing window to become clear, then put onto rinse for 30 seconds. Then return the multi-port valve to the “Filter” position.
With cartridge filter elements remove and clean or replace if required.
Faulty Pump
A faulty pump motor, capacitor or electrical issues can prevent the pump from starting or priming.
Resolve: The pump or capacitor may need to be replaced, if required consult with a pool professional.
Suction Line Blockage
Leaves, twigs, toys or other objects can become stuck in the suction line and cause a blockage, limiting water flow.
Resolve: Try remove the leaves or objects by using a hose and flushing through the pipework.
If the problem persists, consult
with a pool professional.
Impeller Issues
A damaged, worn or clogged impeller can prevent proper priming.
Resolve: Consult with a pool professional.
