Winter-Proof Your Hayward Sand Filter: Ultimate Guide for Homeowners

As the chilly winter months approach, it’s crucial to prepare your Hayward sand filter for the season. Winterizing your filter ensures its longevity and prevents costly repairs in the spring. This comprehensive guide will walk you through the step-by-step process of how to winterize a Hayward sand filter.

Step 1: Gather Necessary Materials

• Screwdriver
• Bucket
• Shop vacuum
• Filter cleaner
• Filter lubricant
• Antifreeze (RV/marine grade)

Step 2: Turn Off the Pump and Power

Unplug the pump and turn off the power supply to the filter. Ensure there is no electricity flowing to the filter before proceeding.

Step 3: Drain the Filter Tank

Use a screwdriver to remove the drain plug at the bottom of the filter tank. Allow the water to drain into a bucket.

Step 4: Clean the Filter

Using a shop vacuum, remove any remaining water and debris from the filter tank. Apply filter cleaner to the filter media according to the manufacturer’s instructions.

Step 5: Lubricate the O-Rings

Apply filter lubricant to the O-rings on the filter head and drain plug. This will prevent them from drying out and cracking during the winter.

Step 6: Add Antifreeze

Pour RV/marine-grade antifreeze into the filter tank. Fill the tank to the top and allow it to circulate through the filter system.

Step 7: Run the Pump for a Few Minutes

Turn the pump back on for a few minutes to circulate the antifreeze throughout the system. This will prevent water from freezing inside the filter.

Step 8: Remove the Filter Head

Unscrew the filter head and remove it from the tank. Pour any remaining antifreeze from the head into the tank.

Step 9: Store the Filter Head and Media

Wrap the filter head in a plastic bag and store it in a warm, dry place. Store the filter media in a sealed container to prevent moisture buildup.

Step 10: Cover the Filter Tank

Cover the filter tank with a tarp or other protective cover to prevent debris and moisture from entering.

Additional Tips

• Consider using a filter freeze guard to prevent the filter from freezing in extremely cold temperatures.
• If you live in a particularly cold climate, you may want to drain the filter tank completely and store it indoors during the winter.
• Inspect the filter regularly during the winter to ensure it remains covered and protected.

Wrapping Up

By following these steps, you can effectively winterize your Hayward sand filter and ensure its optimal performance in the spring. Taking the time to properly winterize your filter will extend its lifespan and save you money on repairs in the long run.
