Keeping your swimming pool in perfect condition requires regular maintenance. One of the most common issues pool owners face is air getting trapped in the pump. Learning how to get air out of pool pump is essential to ensure your pump works efficiently without interruptions.
An air-locked pump can cause poor water circulation, inefficiency, and potential damage to your system. Whether you’re a beginner or an experienced pool owner, this guide will take you step by step through diagnosing and removing air from your pool pump.

Why Air Gets Trapped in a Pool Pump
Before fixing the issue, it’s important to understand why air enters your pump system. Here are some common causes:
- Loose fittings or connections
- A low water level in the pool
- Clogged skimmer basket or filter
- A leaking pump lid o-ring
- Cracks or leaks in the suction lines
Signs That Your Pool Pump Has Air in It
Not sure if there’s air in your pump? Here are some telltale signs:
- Water is not flowing properly through the system
- Visible air bubbles in the pool return jets
- The pool pump makes unusual noises
- The pressure gauge is fluctuating
How to Get Air Out of Pool Pump
1. Turn Off the Pump
Always start by turning off your pool pump to avoid damage or injury. This is crucial when dealing with any pool maintenance tasks.
2. Check the Pool Water Level
Ensure the water level is at least halfway up the skimmer opening. If its too low, air can get sucked into the pump.
3. Inspect the Pump Lid and O-ring
Remove the pump lid and examine the o-ring for dirt, cracks, or wear. Clean or replace it if necessary.
4. Clean Out the Skimmer and Pump Basket
Dirty skimmer and pump baskets can restrict water flow. Remove debris and clean them thoroughly.
5. Tighten Hose Clamps and Connections
A loose connection in the suction line can allow air to enter the system. Tighten all fittings and clamps to secure them properly.
6. Prime the Pump
Fill the pump basket with water, replace the lid, and turn the pump on to force out trapped air.
7. Bleed the Air From the Filter
Many pool filters have an air relief valve. Open it slowly while the pump is running until water starts coming out.
8. Monitor the Pump for Air Bubbles
After performing these steps, check if bubbles are still coming from the return jets. If so, repeat the process or inspect for hidden leaks.
How to Prevent Air from Entering Your Pool Pump
Prevention is key to avoiding repeated air issues. Here are some preemptive steps:
- Maintain the water level in your pool
- Regularly inspect and clean the o-ring
- Ensure all suction lines are sealed tightly
- Clean out filters and skimmers frequently
