Maintaining a Pool Pump: How to Fix Air in the Pool Pump

Keeping your pool pump running efficiently is important to ensure you have clean, healthy swimming water. When air enters a pool pump, the efficiency is affected and the pump’s performance is reduced. Fortunately, there are a few steps you can take to quickly and effectively fix air in your pool pump. In this guide, we discuss the importance of proper air handling, the potential causes of air within a pump, and the steps necessary for removing the air.

Why is Air Handling in a Pool Pump Important?

Good air handling is essential for ensuring your pool pump operates correctly. Air can become trapped within the pump during normal operation and prevent water from flowing through. This can negatively affect the performance and lifespan of the pump. It can also reduce the overall efficiency as the pump will not be able to transfer the water as it was designed.

Potential Causes of Air in the Pool Pump

There are various possible causes of air in a pool pump, some of which include:

Improperly Sealed Lid

If the lid on the pump is not sealed properly, air can enter the pump. This can also cause the vacuum suction to be lost as the air is sucked in. It is important to ensure the lid is securely sealed to avoid this.

Leaky Piping

Another potential cause of air entering the pump is leaky piping. Any areas with a damaged or loose fitting can cause air to leak into the system, further reducing the pump’s performance and increasing air buildup. It is important to frequently check the pipes and fittings to ensure they are secure and able to prevent air leakage.

Gasket Problems

The gasket seals the lid of the pump and can become worn over time. A worn gasket can cause improper vacuum suction, resulting in the pump drawing in air instead of water. It is important to examine the gasket frequently to ensure it is not damaged or worn.

How to Remedy Air in the Pump

Once the cause has been identified, the air needs to be removed from the pump. The following steps can be taken to clean out the air from a pool pump.

Check the Gasket

The first step is to check the gasket for signs of wear or damage. If the gasket is damaged, it will need to be replaced. If it is not damaged, tighten it to ensure it is properly sealed.

Check Piping

Next, check the piping for any loose fittings or areas of obvious leakage. If any are found, they need to be secured. If the piping is old, it may be better to replace it.

Check Valve Action

The valves should be checked to ensure they are functioning properly. If the valves are not positioned correctly, they may be allowing air to enter the system.

Check the Impellor

Next, the impellor needs to be checked to ensure it is not blocked. Debris can easily become stuck in the impellor and cause air to be drawn in.

Re-prime the Pump

If the air is still present, the pump may need to be re-primed. This means removing the lid and adding water to the pump until all the air is expelled. It is important to ensure the lid is securely sealed once the process is complete.

People Also Ask

What does an air-locked pool pump look like?

An air-locked pool pump will have a very low water intake and discharge, making it difficult to filter the water in the pool.

What is the best way to prevent air entering a pool pump?

The best way to prevent air entering a pool pump is to regularly check the gasket, valves, and piping for any signs of wear or damage. Additionally, frequently check the impellor in the pump to ensure it is clear of any debris.

How often should the pool pump lid be checked?

The pool pump lid should be checked at least once a month for signs of wear or damage.

Will air in a pool pump cause damage?

Yes, air in a pool pump can cause damage to the pump as it can reduce its performance and efficiency.

Should air be bled from the pump periodically?

It is beneficial to periodically bleed air from the pump to ensure any air that has built up is removed.

Final Words

Air in a pool pump can affect the performance of the pump and reduce its efficiency. Identifying potential causes of air buildup and following the steps for cleaning it out can help ensure your pump works optimally. By routinely checking the gasket, valves, piping and impellor, air can be prevented from entering the pump and damaging it.
