Having air in your pool pump can be a common issue that affects the efficiency of your pool system. When air gets trapped in the pump, it can cause the water flow to be disrupted, resulting in poor filtration and circulation. Fortunately, there are several steps you can take to get the air out of your pool pump and restore its optimal performance.

1. Check for Leaks

One of the first things you should do is check for any leaks in your pool pump system. Look for loose fittings, cracked pipes, or damaged valves that may be causing air to enter the system. Tighten or replace any faulty parts to prevent air from getting into the pump.

2. Prime Your Pump

If your pool pump is not properly primed, it can lead to air being trapped inside. To prime your pump, turn off the power and remove the pump lid. Fill the pump housing with water until it reaches the top. This will help create a vacuum seal and push out any air that may be present.

3. Check the Water Level

A low water level in your pool can also contribute to air getting into the pump. Make sure the water level is at the appropriate level, usually halfway up the skimmer opening. If the water level is too low, use a garden hose to fill it up to the correct level.

4. Clean the Strainer Basket

A clogged or dirty strainer basket can obstruct water flow and cause air to be trapped in the pump. Turn off the pump and remove the strainer basket. Clean it thoroughly by rinsing it with a hose to remove any debris or obstructions. Reinstall the basket and ensure it fits tightly to prevent air leaks.

5. Check the Pump Lid O-ring

The pump lid has an O-ring that helps create a seal and prevent air from entering the pump. Over time, this O-ring can become worn or loose, leading to air leaks. Inspect the O-ring for any signs of damage or wear and replace it if necessary. Apply a thin layer of lubricant to the O-ring to ensure a proper seal.

6. Bleed Air from the System

To remove air from the pool pump, you can try bleeding the air out of the system. Locate the air bleed valve on the filter or pump and open it slightly to release any trapped air. Keep an eye on the pressure gauge and close the valve once water starts flowing steadily without any air bubbles.

7. Check the Pump Impeller

A blocked or damaged pump impeller can also cause air to be trapped in the pump. Turn off the power and remove the pump housing to access the impeller. Inspect it for any debris or obstructions and clean it if necessary. Replace the impeller if it is damaged or worn out.

8. Inspect the Pump Lid Seal

The pump lid seal is another potential source of air leaks. Inspect the seal for any cracks or damage and replace it if needed. Apply a small amount of lubricant to the seal to ensure a tight and secure fit.

9. Consider Installing a Check Valve

A check valve can help prevent air from entering the pump by only allowing water flow in one direction. Install a check valve on the suction side of the pump to ensure that water flows smoothly and air is kept out. Consult a professional if you are unsure about the installation process.

10. Regular Maintenance

To avoid future air-related issues, it is important to perform regular maintenance on your pool pump. Clean the strainer basket, inspect the O-rings, and check for any leaks or blockages. Regularly monitoring and maintaining your pool pump will help ensure its longevity and efficiency.

In conclusion, getting air out of your pool pump requires a systematic approach. By following these steps and performing regular maintenance, you can keep your pool pump running smoothly and enjoy crystal-clear water in your pool.
