Pool pumps are essential equipment for maintaining the cleanliness of a swimming pool. They work by circulating water through the pool’s filtration system, removing debris and contaminants. However, if air gets into the pool pump, it can cause a variety of problems that can affect the pump’s performance and even damage it. In this article, we will explore what happens when air gets into a pool pump and how to prevent and fix this issue.
What Causes Air to Get into a Pool Pump?
There are several reasons why air can get into a pool pump:
- A leak in the suction side of the pool pump
- A clogged skimmer or pump basket
- A damaged or worn-out pump lid o-ring
- An improperly sealed pump lid
- A damaged suction line or valve
What Happens When Air Gets into a Pool Pump?
When air gets into a pool pump, it can cause several issues:
- Cavitation: Cavitation occurs when air bubbles form in the pump impeller, causing the impeller to spin faster and creating a low-pressure area that can damage the impeller and other pump components over time.
- Reduced Efficiency: When air gets into the pump, it can reduce the pump’s efficiency, causing it to work harder and consume more energy.
- Loss of Prime: Air in the pump can cause the water to lose its prime, which means the water will not circulate properly and the pool will not be cleaned effectively.
- Noise: Air in the pump can cause a loud, whining noise as the impeller spins faster than it should.
- Pump Damage: If left unchecked, air in the pump can cause damage to the impeller, seals, and other components, leading to costly repairs or replacement.
How to Prevent Air from Getting into a Pool Pump
The best way to prevent air from getting into a pool pump is to ensure that the pump’s suction side is airtight. Here are some steps you can take:
- Check for leaks: Inspect the suction line, valves, and fittings for leaks. If you find any, repair or replace them immediately.
- Clean the skimmer and pump basket: Regularly clean the skimmer and pump basket to prevent clogs that can cause air to get into the pump.
- Check the pump lid o-ring: Inspect the pump lid o-ring for damage or wear and replace it if necessary.
- Ensure the pump lid is properly sealed: When closing the pump lid, make sure it is properly sealed to prevent air from getting in.
How to Fix Air in a Pool Pump
If air does get into your pool pump, there are several steps you can take to fix the problem:
- Check the water level: Ensure that the pool water level is high enough to cover the skimmer and pump intake.
- Prime the pump: Turn off the pump and open the air relief valve on the filter to allow any trapped air to escape. Then, close the valve and turn on the pump to prime it.
- Check for leaks: Inspect the suction line, valves, and fittings for leaks and repair or replace them if necessary.
- Replace the pump lid o-ring: If the o-ring is damaged or worn, replace it with a new one.
Conclusion
Air in a pool pump can cause a variety of problems, including reduced efficiency, loss of prime, cavitation, noise, and pump damage. By taking steps to prevent air from getting into your pool pump and fixing the problem if it does occur, you can ensure that your pool stays clean and healthy while prolonging the life of your pump.
