Why and How to Change Sand in Your Pool Filter

Owning a swimming pool provides a lot of fun and relaxation, but it also comes with a specific duty. One crucial maintenance activity is replacing the sand in your pool filter. Over time, the sand in your pool filter may become dusty and less effective in filtering the water. This guide will explain why changing the sand in your pool filter is essential, how to tell when it's time, and how to do it step by step.

Why Change the Sand in Your Pool Filter?

Importance of Clean Sand

Sand in your pool filter is essential for keeping your pool water clean and clear. As water goes through the filter, the sand detains dirt, trash, and other particles, preventing them from returning to the pool. Over time, the sand becomes clogged with contaminants, limiting its efficiency.

Benefits of Regular Sand Replacement

  • Improved Filtration Efficiency: New sand ensures optimal filtration, capturing even the smallest particles and keeping in your pool filter water clear.
  • Enhanced Water Circulation: Clean sand allows water to flow freely through the filter for improving overall pool circulation. 
  • Extended Filter Lifespan: Regularly changing the sand in your sand filter can extend the life by preventing clogs and reducing strain on the system.
  • Energy Efficiency: A clean filter system operates more efficiently, potentially lowering your pool’s energy consumption and operational costs.

When to Change the Sand in Your Pool Filter

Signs That It’s Time to Change the Sand

  • Cloudy Pool Water: If your pool water remains cloudy despite regular or weekly pool maintenance, it might indicate that the sand is no longer effectively filtering the water.
  • Increased Backwashing Frequency: If you need to backwash the filter more often than usual, it could be a sign that the sand is clogged and unable to perform efficiently.
  • High Filter Pressure: A regularly high pressure reading on your filter gauge indicates that the water flow is restricted, likely due to dirty sand.
  • Visible Debris: If you notice debris returning to the pool after passing through the filter, the sand may need replacing.

When to Replace Sand in Pool Filter?

Generally, the sand in your pool filters should be replaced every 3-5 years. However, this varies based on pool usage, filter size, and sand quality. Regularly looking for the symptoms mentioned above can assist you in determining the optimum timetable for your pool.

How to Change the Sand in Your Pool Filter: A Step-by-Step Guide

Step 1: Turn Off the Pool Pump

Before you begin, switch off the pool pump and unhook the power supply to guarantee safety.

Step 2: Drain the Filter

Locate and remove the pool filter drain plug at the base of the filter tank to allow the water to drain out. You may need a bucket to collect or direct the water to an appropriate drainage place.

Step 3: Remove the Multiport Valve

Using a screwdriver, loosen and remove the clamps or bolts holding the multiport valve to the top of the filter tank. Carefully remove the valve from the tank and place it aside.

Step 4: Remove the Old Sand

Use a shop vacuum or scoop to remove the old sand from the filter tank carefully. Be careful not to damage the sand filter laterals (the filter's internal components).

Step 5: Inspect and Clean the Laterals

After removing the old sand, check the laterals for any signs of damage or wear. If you notice sand in your swimming pool from the pump, it may indicate a broken lateral or other issues within the sand filter that need immediate attention. It might be time to replace the pool pump to ensure optimal performance. Clean the laterals thoroughly with a garden hose to ensure they are debris-free. Regular sand filter lateral replacement is crucial for maintaining effective filtration and ensuring the longevity of your pool's filtration system.

Step 6: Add New Sand

Fill the filter tank halfway with water to soften the laterals while adding additional sand. Slowly pour the filter sand replacement into the tank, ensuring it is properly spread. Refer to your filter’s handbook for the right amount of sand needed.

Step 7: Reassemble the Filter

Replace and secure the multiport valve atop the filter tank with the clamp or bolts. Apply Teflon tape to the threads to ensure a secure seal. Reinstall the drain plug and any other removed components.

Step 8: Backwash and Rinse

Restart the pool pump and set the multiport valve to the backwash position. Run the pump for a few minutes to clear any remaining dust and debris from the new sand. After backwashing, turn the valve to the rinse position and run the pump for another minute and this is best way to pool filter long lasting use.

Step 9: Resume Normal Operation

Finally, the multiport valve is turned to the filter position and resumes regular pool operation. Check the filter's pressure gauge and water clarity to ensure everything works correctly.
