1. Remove pool accessories: Start by removing all pool accessories, including ladders, diving boards, and pool toys. Store them in a dry place where they won’t be damaged by the cold weather.
2. Clean the pool: Make sure your pool is as clean as possible by removing all leaves, silt, and other debris. This will make it easier to balance the water chemistry and prevent mold and algae growth. Use skim nets to clean the surface of the water, and a pool vacuum to clean the bottom of the pool.
3. Balance water chemistry: Test the water chemistry and make sure it is properly balanced. Adjust the pH, alkalinity, and calcium hardness levels as needed. This will help prevent corrosion and scaling during the winter months.
4. Lower the water level: Lower the water level in the pool to below the skimmer level. This will prevent the skimmer from freezing and cracking during the winter. Use a submersible pump to lower the water level if necessary.
5. Drain water from pool equipment: Drain all water from the pool equipment, including the pump, filter, and heater. This will prevent damage from freezing and ensure that the equipment is in good condition when you start it up again in the spring.
6. Blow out the plumbing lines: Use a shop vac or air compressor to blow out the plumbing lines. This will remove any remaining water and prevent freezing and damage to the pipes.
7. Add winterizing chemicals: Add winterizing chemicals to the pool to prevent algae growth and other issues during the winter. Follow the manufacturer’s instructions for the proper dosage.
8. Install a winter cover: Install a winter cover over the pool to keep out debris and prevent evaporation. Make sure the cover is properly secured and tight-fitting.
9. Monitor the pool: Check the pool periodically during the winter to make sure the cover is still secure and there are no issues with the pool.
10. Open the pool in the spring: When the weather starts to warm up, it’s time to open the pool again. Remove the winter cover, clean the pool, and balance the water chemistry before starting up the equipment.

By following these steps, you can winterize your in-ground pool and protect it from damage during the colder months. Proper winterization will help ensure that your pool is in good condition when you open it back up again in the spring.

1. Clean the pool: Before closing your pool, it’s important to clean it thoroughly. This includes removing any debris from the water and cleaning the walls and floor of the pool. You should also brush the walls and floor to remove any algae or other buildup.
2. Balance the water chemistry: It’s important to balance the water chemistry in your pool before closing it for the winter. This includes adjusting the pH, alkalinity, and calcium hardness levels. You should also shock the pool to kill any bacteria or algae that may be present.
3. Lower the water level: You should lower the water level in your pool to just below the skimmer. This will prevent the water from freezing and expanding, which can damage the pool’s plumbing and structure. If you live in an area with thaws or a rainy winter, it’s a good idea to check the water level while the pool is closed.
4. Add winterizing chemicals: Once the water level has been lowered, you should add winterizing chemicals to the pool. This includes adding a winter algaecide and a winterizing kit that contains a winterizing chemical, a stain and scale inhibitor, and a metal sequestrant.
5. Install a winter cover: Finally, you should install a winter cover over your pool. This will protect it from debris and prevent animals from getting into the pool. Make sure the cover is securely fastened to prevent it from blowing off during winter storms.

Closing an inground pool for the winter can be a daunting task, but it’s important to do it properly to protect your pool and ensure that it’s ready to use again in the spring. By following these steps, you can close your pool without draining the water and avoid any potential damage to your pool’s structure and plumbing.
