Properly winterizing your pool is essential to ensure that it remains in good condition during the colder months and is ready to use when summer rolls around again. If you’ve never winterized your pool before or need a refresher on the process, here is everything you need to know.

1. Clean and Balance the Water

Before winterizing your above ground pool, it is crucial to clean and balance the water. Use a pool skimmer or net to remove any floating debris, and thoroughly vacuum the pool to remove any dirt and leaves at the bottom. Test the water’s pH, alkalinity, and chlorine levels, and make any necessary adjustments to ensure they are within the recommended range. Properly balanced water will help protect your pool during the winter months.

2. Remove Pool Accessories

Next, remove all pool accessories from the pool, such as ladders, diving boards, or slides. Clean and dry these items thoroughly before storing them in a safe and dry place for the winter. Removing the accessories will minimize the risk of damage caused by freezing temperatures and ensure they are ready to use when the pool is open again.

3. Lower the Water Level

Lowering the water level in your above ground pool is an important step in winterizing. Use a submersible pump or a siphon to drain the water to the appropriate level. Depending on your pool’s construction and the manufacturer’s recommendations, the water level should be lowered below the skimmer and return lines to prevent freezing and potential damage.

4. Drain and Clean the Filter System

Properly draining and cleaning your pool’s filter system is crucial before winterizing. First, turn off the pool pump to prevent water flow. Then, drain the filter and remove any debris or dirt. Refer to your pool’s specific instructions to ensure you are following the correct steps. Thoroughly clean the filter components before storing them for the winter. This will help prevent any clogs or damage to the filter system during the colder months.

5. Add Winterizing Chemicals

Adding winterizing chemicals is an essential step in protecting your above ground pool during the winter. Follow the manufacturer’s instructions carefully to determine the appropriate amount of chemicals to add based on your pool’s volume. Typically, winterizing chemicals include a winter algaecide, which helps prevent algae growth, and a winter chlorine kit or shock treatment. These chemicals will ensure that the water remains clean and clear throughout the winter season.

6. Cover the Pool

After all the necessary steps have been completed, it’s time to cover your above ground pool. Choose a high-quality pool cover that is specifically designed for above ground pools. Make sure the cover fits the pool tightly and securely, preventing debris from entering and protecting the pool’s structure. Additionally, ensure that the cover has appropriate drainage holes to prevent water accumulation during heavy rain or snow.

7. Regular Maintenance Checks

Winterizing your above ground pool doesn’t mean you can forget about pool maintenance entirely. It is essential to perform regular checks throughout the winter season to ensure the pool is in good condition. After storms or heavy snowfall, remove any debris from the cover and inspect it for any signs of damage. Additionally, keep an eye on the water level and snow accumulation to prevent any potential structural issues.


Winterizing your above ground pool is a crucial step to protect it during the colder months and ensure its longevity. By following these steps and properly cleaning, balancing the water, removing accessories, lowering the water level, draining, and cleaning the filter system, adding winterizing chemicals, and covering the pool, you can rest assured that your pool will be in excellent condition when summer arrives. Regular maintenance checks during the winter will further ensure that any potential issues are addressed promptly. Stay proactive and enjoy a stress-free winter knowing your above ground pool is properly winterized.
