How to Close an Above Ground Pool

As the summer comes to an end, it’s time to start thinking about closing your above ground pool. Properly closing your pool is essential to ensure it stays in good condition during the winter months and is ready to be enjoyed again next season. In this article, we will guide you through the step-by-step process of closing an above ground pool.

Step 1: Clean and Balance the Water

The first step in closing your above ground pool is to clean and balance the water. Start by skimming the surface of the water to remove any debris. Then, brush the sides and bottom of the pool to loosen any dirt or algae. Vacuum the pool to remove all the debris from the bottom.

Once the pool is clean, it’s important to balance the water chemistry. Test the water and adjust the pH, alkalinity, and calcium hardness levels to the recommended ranges. This will help prevent any damage to the pool’s surface during the winter months.

Step 2: Lower the Water Level

Before closing your above ground pool, you’ll need to lower the water level. Use a submersible pump or a pool cover pump to drain the water to about 4-6 inches below the skimmer. This will help prevent any freezing and expansion of the water during the winter.

Step 3: Remove Accessories

Next, remove any accessories from the pool such as ladders, diving boards, or slides. Clean and dry them thoroughly before storing them away for the winter. This will prevent any damage or deterioration.

Step 4: Winterize the Plumbing

To prevent any damage to the plumbing system, it’s important to winterize it. Start by disconnecting the pump, filter, and heater. Drain all the water from these components and store them in a dry place. Use a winterizing plug to seal the return and skimmer lines.

If your above ground pool has an automatic chlorinator or saltwater system, remove it and store it away as well. These components are not designed to withstand freezing temperatures.

Step 5: Install a Winter Cover

Now it’s time to install a winter cover to protect your above ground pool during the winter months. Start by spreading the cover over the pool, making sure it’s centered and aligned properly.

Secure the cover using water bags or cover clips. Water bags should be placed around the edge of the pool, while cover clips can be used to secure the cover to the top rail of the pool. This will prevent the cover from being blown away by strong winds.

Step 6: Winterize the Pump and Filter System

Lastly, you’ll need to winterize the pump and filter system. Start by removing the drain plugs from the pump and filter. This will allow any remaining water to drain out and prevent freezing.

Store the drain plugs in a safe place, so you can easily find them when it’s time to open the pool again. Cover the pump and filter system with a plastic bag or tarp to protect them from the elements.


Closing an above ground pool properly is crucial to protect it during the winter months. By following these steps, you can ensure that your pool stays in good condition and is ready to be enjoyed again next summer. Remember to clean and balance the water, lower the water level, remove accessories, winterize the plumbing, install a winter cover, and winterize the pump and filter system. With proper care, your above ground pool will last for many years to come.
