However, with the right knowledge and preparation, the process can be much easier and ensure that your pool is properly protected during the winter months. In this blog post, we’ll provide you with the ultimate guide to closing down your in-ground pool, complete with step-by-step instructions and helpful tips.

1. Clean and Balance the Water

Before closing your pool, it’s essential to ensure that the water is clean and properly balanced. Start by vacuuming the pool to remove any debris or dirt. Next, test the water using a pool water testing kit and adjust the chemicals accordingly. The pH levels should be between 7.4 and 7.6. Additionally, shock the pool with a suitable pool shock treatment to kill any bacteria or algae present in the water.

2. Remove Pool Accessories

The next step is to remove any pool accessories such as ladders, diving boards, or slides. Clean and dry these items before storing them in a safe place for the winter. This will help prevent damage and extend the lifespan of your pool accessories.

3. Lower the Water Level

To avoid potential damage caused by freezing and expanding water, it’s crucial to lower the water level in your pool. Use a submersible pump or a sand filter (backwashing technique) to drain the water until it reaches 4 to 6 inches below the skimmer opening. Be cautious not to drain all the water, as some water is necessary to keep the pool structure stable during the winter.

4. Drain and Winterize Pool Equipment

Properly draining and winterizing your pool equipment is essential to protect them from freezing temperatures. Start by draining the water from the filter, pump, and heater. Remove any drain plugs and ensure that all water is completely drained from these components. Additionally, clean and empty the chlorinator and chemical feeders, as any residual chemicals can cause damage over time. Finally, disconnect and store any hoses or pipes that are connected to the pool equipment.

5. Clean and Cover

Once the pool has been properly prepared, it’s time to give it one final cleaning before covering it for the winter. Use a pool brush and skimmer to remove any remaining debris from the walls and surface of the pool. Additionally, clean the tile line and empty the skimmer and pump baskets. Finally, cover the pool with a high-quality pool cover that is designed specifically for in-ground pools. Make sure the cover is securely fastened to prevent any debris from getting into the pool during the winter months.

6. Monitor and Maintain

Even though your pool is closed for the winter, it’s important to continue monitoring and maintaining it throughout the season. Periodically check the pool cover for any damage or sagging. Remove any debris that may accumulate on top of the cover. Additionally, check the water level and make sure it stays within the recommended range. If necessary, add water to the pool to maintain the proper level.


By following these steps and taking the necessary precautions, you can successfully close down your in-ground pool for the winter season. Remember, proper maintenance and care during the winter months will ensure that your pool remains in good condition and is ready for use when warmer weather returns.
