Step 1 – Turn Off Power to the Pool Pump

The process of turning off the power to your pool is a crucial step. This will ensure your pump or other parts of your pool won’t run at the wrong time. For instance, having a pump that runs without water or the correct circulation can break the pump or cause damage. This damage will cost you money.

Therefore, the simplest way to accomplish this step is to flip the power breaker connected to your pool. This will cut all power to the pool and allow you to prime your pump without any fear of damage.

Step 2 – Turn the Multiport Valve on Your Pool Pump to Circulate

After the power to your pool has been cut, it’s time to get to work. Turning your multiport valve to circulate is key to priming your pool pump.

The circulate setting on your pump means that water will only run in and out through the multiport valve and will NEVER go into the pool filter system. This setting is useful because it allows you to do work on your pump and filter without any water getting into somewhere it shouldn’t.

Step 3 – Fill Your Pool Pump with Water

After your valve is set to circulate, it’s officially time to prime! Start by removing the lid of your pool pump. If you don’t know how to do this, refer to your pump’s directions and there likely will be instructions for removing the lid without damaging the pump. 

Because you made sure your lid was taken off correctly, it’s time to move on. Next, take a garden hose or another watering device and place it inside of the basket on the pump. Start filling the basket with water. Usually there will be marked water lines in the basket. However, if not, we recommend filling for a few minutes until the water looks high enough to create a suction in the pool pump.

Step 4 – Turn Your Filter System Back On

Once the water levels are high enough in your pump, turn your filter system back on. This step is necessary to check the suction and priming of your pump. 

You will know that you did the previous steps correctly if the water starts running from the basket and into the actual housing of the pump. Make sure there are no air bubbles visible in any part of the system, because if there is the suction is likely not as strong as it should be. Because we need the pool to be primed correctly, this step is crucial to know you did the job well.

Step 5 – Enjoy Your Primed Pool Pump

With all of these steps complete, your pump has been successfully primed. You will need to repeat this process as needed. Signs of low or no water in the pump will be a low pressure reading on the pool filter, or little or no water physically in the pump strainer.

In conclusion, your pool pump is primed and ready for action, it’s time to enjoy your pool with your loved ones!
