How to Winterize/Close your In-Ground Pool!

Introduction

This tutorial will guide you through the process of winterizing your in-ground swimming pool. Properly closing your pool for the season is essential to protect it from damage caused by freezing temperatures and debris accumulation. Whether you're in a colder climate or milder areas, this guide covers all the necessary steps and materials needed for a successful winterization.

Step 1: Gather Necessary Materials

Before you begin the winterization process, ensure you have the following materials on hand:

• Winter cover (specific size for your pool)
• Skimmer guard (Gizzmo)
• Water bags or tubes for securing the cover
• Eyeball fitting removal tool
• 1.5" threaded plug with O-ring
• Pool chemicals for balancing water

Step 2: Balance the Water

Balancing the pool water is crucial before closing it down for winter. Follow these steps:

1. Test the water's pH, alkalinity, and chlorine levels.
2. Adjust the pH level to between 7.2 and 7.6.
3. Ensure alkalinity is between 80-120 ppm.
4. Maintain chlorine levels appropriate for winterizing (typically around 3-5 ppm).

Step 3: Install Winter Cover

Once the water is balanced, you can install the winter cover:

1. Clean the pool surface to remove any debris.
2. Lay the winter cover over the pool.
3. Use water bags or tubes around the perimeter to secure the cover, preventing it from blowing away.

Step 4: Use the Skimmer Guard

Protect your skimmer from freezing damage with a skimmer guard:

1. Remove the skimmer basket.
2. Insert the skimmer guard (Gizzmo) into the skimmer opening.
3. Ensure it is secure and fits snugly to prevent water from entering.

Step 5: Winterize the Pool System

Winterizing the pool system is essential, especially if you have a chlorinator or heater:

1. Turn off and disconnect the heater and chlorinator.
2. Drain all water from the pump, filter, and heater to prevent freezing.
3. For systems lower than the pool, use a shop vac to blow out the lines and remove any remaining water.
4. Plug the lines to prevent water entry.

Step 6: Winterizing in Cold Climates

If you live in an area that experiences freezing temperatures, take extra precautions:

1. Consider using antifreeze in the plumbing lines to prevent freezing.
2. Monitor the weather to adjust your winterization steps as needed.

Conclusion

Winterizing your in-ground pool is a vital task to ensure it remains in good condition for the next swimming season. By following these steps—gathering the right materials, balancing the water, securing the cover, using a skimmer guard, and properly winterizing the system—you can protect your investment and simplify the reopening process in spring.
