How to Prime a Swimming Pool Pump: A Comprehensive Guide

Swimming pools are a perfect way to relax and unwind after a long day, especially during the hot summer months. However, to keep your pool clean and sparkling, you need a fully functioning pool pump. The pool pump is responsible for circulating water through the filtration system, which traps all sorts of debris, bacteria, and dirt. However, sometimes, the pump may stop working, especially if it loses its prime. In this article, we provide you with a comprehensive guide on how to prime a swimming pool pump.

What Does it Mean to Prime a Pool Pump?

Priming refers to the process of removing air from the pool pump and filter system, which allows water to flow freely. When your pool pump loses its prime, you may notice that water is not circulating through the system, leading to reduced water quality, and ultimately creating an unsightly swimming experience. When you prime the pool pump, you ensure that there is no air in the system, which prevents the pump from overheating and being damaged.

Step-by-Step Guide on How to Prime a Swimming Pool Pump

Priming a pool pump can seem daunting at first, but it is relatively easy, and you don't need a professional to do it for you. Here is a step-by-step guide on how to prime your swimming pool pump.

Step 1: Turn off the Pool Pump

Before you prime the pool pump, start by turning it off. This step is essential as it prevents the pump from overheating and breaking down. Additionally, you should turn off the pool heater and any other pool equipment connected to power.

Step 2: Check the Water Level

Ensure that the water level in the pool is above the skimmer. If the water level is low, the pump may not be able to circulate water effectively, leading to an airlock. To prevent the pump from losing its prime, ensure that the water is at the correct level.

Step 3: Clean the Pool Pump

Cleaning the pool pump helps to ensure that there is no debris or leaves clogging the impeller, which may prevent water from flowing through the system. You can clean the pool pump by removing the pump basket and cleaning it using a hose. Additionally, check the impeller and ensure that there is no debris, leaves, or anything that may restrict water flow.

Step 4: Add Water to the Pump

Adding water to the pump helps remove air from the system, which can cause the pump to lose its prime. You can add water using a garden hose, which you will insert into the skimmer until it reaches the bottom of the pool. Turn on the water and add water to the pump until it's full.

Step 5: Close the Pump Lid

After adding water to the pump, close the pump lid tightly. It's essential to ensure that the lid is securely closed as it prevents air from entering the system and causing the pump to lose its prime.

Step 6: Turn on the Pump

After closing the pump lid, it's time to turn on the pump. Switch on the pump and let it run for a few minutes. As the water circulates through the system, you may notice that the water pressure rises, and the filter begins to collect debris.

Step 7: Monitor the Pool Pump

Monitor the pool pump to ensure that it's working correctly. If you notice that the water is not flowing, you may need to prime the pump again. Additionally, if you hear any unusual noise or the pump is vibrating aggressively, turn it off and check it for problems.


Priming your pool pump is an essential process that helps keep your swimming pool clean and inviting. A lot can go wrong with a pool pump, which is why it's essential to know how to prime it. With this comprehensive guide, you now know how to prime your swimming pool pump, ensuring that your pool remains clean and sparkling throughout the year. Remember to maintain your pool pump regularly to prevent it from losing its prime and prolong its lifespan.
