If your Intex sand filter pump is showing air bubbles or air in the system, it can reduce filtration efficiency. Getting air out of your sand filter pump is simple with the right steps. This guide walks you through easy methods to remove trapped air, ensuring your pool stays clean and clear.

How to Get Air Out of Intex Sand Filter Pump

If you’ve noticed your Intex sand filter pump isn’t working optimally or seeing air bubbles in your pool’s return jets, it’s likely trapped air in your system. Air in the pump or filter can cause poor circulation, cloudy water, or pump damage over time. Fortunately, removing air from your Intex sand filter pump is straightforward. This guide will walk you through each step, helping you restore efficient filtration and keep your pool sparkling clean.

Key Takeaways

• Understanding the cause: Air can enter your sand filter pump through leaks or improper setup, affecting performance.
• Priming the pump: Properly priming the pump is essential to remove air and start effective filtration.
• Checking the multi-port valve: Ensure the valve is correctly positioned to facilitate air removal.
• Bleeding trapped air: Use the air relief valve or vent to release air from the system.
• Maintaining the sand bed: Properly backwash and rinse the sand to prevent air pockets.
• Consistent maintenance: Regularly inspect hoses and fittings for leaks to prevent air ingress.

Understanding Why Air Gets Trapped

Before diving into the steps, it’s helpful to understand why air gets into your sand filter system. Common causes include:

• Leaks in hoses, fittings, or pump lid
• Improper setup or not priming the pump correctly
• Low water levels in the pool
• Air pockets forming in the sand bed during backwashing

Knowing these causes helps in preventing future air issues and maintaining your pool’s filtration system.

Preparation Before Removing Air

Gather Necessary Tools and Supplies

• Intex sand filter pump
• Hoses with fittings
• Pool water (to top off if needed)
• Towel or rag (for spills)
• Optional: Silicone lubricant (for fitting seals)

Ensure Safety and Readiness

Turn off the pump before starting. Make sure the area around your pump is clear. Wearing gloves can help if you need to handle any fittings or sealant.

Step-by-Step Guide to Get Air Out of Intex Sand Filter Pump

Step 1: Turn Off the Pump and Inspect Connections

Start by turning off the pump and unplugging it from the power source. Carefully inspect all hoses, fittings, and the pump lid for leaks or cracks. Tighten loose fittings and replace any damaged parts. Leaks can allow air to enter the system.

Step 2: Fill the Pump Basket with Water

Open the pump lid and fill the pump basket with pool water. This helps create a seal and primes the pump, reducing the chances of air getting trapped.

• Remove the lid carefully.
• Pour water into the basket until it’s full.
• Replace the lid securely, ensuring it’s tightly sealed.

Tip: Use a garden hose to fill the basket directly if needed.

Step 3: Set the Multi-Port Valve Correctly

Ensure the multi-port valve is set to the “Filter” position. If it’s on “Backwash” or “Rinse,” air can get trapped. Turning it to “Filter” allows water to circulate properly and helps expel air pockets.

Step 4: Prime the Pump

Priming the pump involves removing trapped air so water can flow freely. Follow these sub-steps:

4.1: Bleed Air Using the Air Relief Valve (if available)

• Locate the air relief valve or air vent on your pump (usually near the top).
• Slowly open the valve or vent to release trapped air.
• Watch for water to start flowing out. Once water flows steadily without air bubbles, close the valve tightly.

4.2: Manually Prime the Pump

• If your pump has a priming port, pour water into it to fill the pump chamber.
• Ensure all air is expelled before sealing the priming port.

Step 5: Restart the Pump and Observe

Plug the pump back in and turn it on. Watch the water flow and listen for irregular noises, which can indicate trapped air. If you see persistent air bubbles or the pump loses prime, proceed to the troubleshooting section below.

Step 6: Repeat if Necessary

If air bubbles persist, repeat the priming process. Sometimes, it takes a few attempts to completely remove all air pockets.

Additional Tips for Preventing Air in Your Intex Sand Filter Pump

• Maintain proper water level: Keep the pool water at the recommended height to prevent the pump from sucking air.
• Secure fittings tightly: Regularly check hoses and fittings for tightness and signs of wear.
• Backwash and rinse regularly: Proper maintenance of the sand bed prevents air pockets and improves filtration.
• Use high-quality hoses and fittings: Cheap or damaged fittings are more prone to leaks and air ingress.

Troubleshooting Common Air-Related Issues

Persistent Air Bubbles After Following Steps

If bubbles continue after priming, check for leaks in hoses, fittings, or the pump lid. Replace damaged parts and ensure all seals are tight.

Pump Losing Prime Frequently

This can happen if there’s a leak or a crack in the system. Inspect all connections, replace worn parts, and ensure the water level is adequate.

Low Water Flow Rate

May indicate trapped air or clogged sand. Backwash the filter, check for blockages, and ensure the pump is primed correctly.

Conclusion

Removing air from your Intex sand filter pump is essential for maintaining clear, healthy pool water. By following these simple steps—checking connections, priming the pump, and maintaining your equipment—you can effectively eliminate trapped air. Regular maintenance and inspection will prevent future issues, ensuring your pool stays inviting all season long.
