How to Resuscitate Your Sand Filter After Winter’s Icy Grip: Step-by-Step Guide

As the warm weather approaches, it’s time to prepare your pool for the swimming season. After a long winter of inactivity, your sand filter needs some attention to get it back in working order. This comprehensive guide will walk you through the step-by-step process of starting your sand filter after winter, ensuring crystal-clear water for your swimming enjoyment.

Step 1: Remove the Winter Plug and Drain Plug

Locate the winter plug on the side of the filter tank and remove it. This will allow any accumulated water to drain out. Next, remove the drain plug at the bottom of the tank to drain all remaining water.

Step 2: Inspect the Filter Media

Once the filter is drained, inspect the sand or glass media for any damage or debris. If the media is dirty or clogged, it may need to be replaced or cleaned.

Step 3: Fill the Filter with Water

Slowly fill the filter tank with water through the backwash port. Keep the water level about 6 inches below the top of the tank.

Step 4: Open the Air Relief Valve

Locate the air relief valve on top of the filter and open it. This will allow air to escape as the filter fills with water. Close the valve once water begins to flow out.

Step 5: Start the Pump

Turn on the pump and let it run for a few minutes. This will circulate the water through the filter and remove any remaining air.

Step 6: Backwash the Filter

Switch the filter valve to the “backwash” position. This will reverse the flow of water through the filter, flushing out any dirt or debris. Backwash for about 2-5 minutes, or until the water runs clear.

Step 7: Rinse the Filter

Once the filter has been backwashed, switch the valve to the “rinse” position. This will flush out any remaining backwash water. Rinse for about 30 seconds.

Step 8: Set the Filter to Filter Mode

Switch the filter valve to the “filter” position. This will allow the filter to start filtering the pool water.

Troubleshooting Common Problems

• The filter is not filling with water: Check the water supply to the filter and make sure it is turned on. Also, ensure that the pump is properly primed.
• The filter is not filtering properly: Check the filter media for damage or clogging. If necessary, replace or clean the media.
• The filter is leaking: Check the filter for any cracks or damage. If necessary, replace the damaged parts.

Tips for Maintaining Your Sand Filter

• Clean or replace the filter media regularly to ensure optimal filtration.
• Backwash the filter every few weeks to remove dirt and debris.
• Check the pump and filter for any leaks or damage.
• Cover the filter during the winter months to protect it from the elements.

Final Note: Revitalizing Your Pool Filter for Summer Fun

By following these steps, you can successfully start your sand filter after winter and enjoy a clean and refreshing pool all season long. Remember to perform regular maintenance to keep your filter operating efficiently and provide you with crystal-clear water for your swimming enjoyment.
