How To Prime A Pool Pump

June 23, 2023

A properly functioning pool pump helps keep your swimming pool water crystal clear. However, one common issue you may face with pool pumps is the loss of prime. When a pool pump loses its prime, it fails to circulate water effectively, which can lead to a range of problems, such as poor water filtration and inefficient chemical distribution. In this blog, we will walk you through the step-by-step process of priming a pool pump so that you can continue enjoying your swimming pool.

Understanding Pool Pump Priming

Before we dive into the priming process, let’s first understand what it means for a pool pump to lose its prime. Pool pumps work by creating suction to pull water from the pool through the skimmer and main drain and then pushing it through the filter and back into the pool. When a pool pump loses its prime, it means that the pump has lost its ability to create suction due to air entering the system. This can happen for various reasons, such as a clogged impeller, air leaks in the system or an insufficient water level in the pool.

Step 1: Turn Off the Pool Pump

This is important for your safety and to prevent any damage to the pump or its components. Locate the power switch or circuit breaker that controls the pump and switch it off.

Step 2: Inspect and Clean the Pump Basket

The pump basket collects debris and prevents it from entering the pump impeller. Remove the pump lid by twisting it counterclockwise and carefully lift it off. Take out the pump basket and empty its contents. Inspect the basket for any damage or blockages, and if necessary, clean it using a garden hose or a brush.

Step 3: Fill the Pump Basket with Water

This step helps to prime the pump by removing any air trapped in the system. Use a garden hose or a bucket to fill the pump basket with water until it reaches the top. Ensure that there are no air bubbles in the basket.

Step 4: Check and Close the Pump Lid

Before resealing the pump, inspect the lid and O-ring for any signs of damage or wear. A damaged O-ring can cause air leaks and hinder the priming process. If necessary, replace the O-ring with a new one. Place the lid back on the pump and tighten it clockwise until it is secure.

Step 5: Open the Air Relief Valve

To release any remaining air in the system, locate the air relief valve on the pool filter or pump. Slowly turn the valve counterclockwise to open it. You will hear a hissing sound as the air escapes. Once the water starts to come out of the valve, close it by turning it clockwise.

Step 6: Turn on the Pool Pump

With the pump primed and the air released, it’s time to turn the pump back on. Go to the power switch or circuit breaker and switch it on. Allow the pump to run for a few minutes to ensure that it has regained its prime. During this time, monitor the pump and check for any signs of air bubbles or unusual noises.

Step 7: Monitor and Adjust the Water Level

After the pump has been running for a few minutes, check the water level in the pool. If it is below the recommended level, add water using a garden hose until it reaches the optimal range. Maintaining the correct water level is important for the pump to function efficiently and avoid losing its prime.
