As colder weather approaches, it’s crucial to prepare your inground pool for winter. Proper winterization extends the life of your pool and ensures it’s ready for use come spring. Taking steps to winterize will prevent damage from freezing temperatures and reduce maintenance efforts when the weather warms up again.

Winterizing your inground pool involves several important tasks. From cleaning and checking your pool to balancing the water chemistry, each step is vital to protecting your pool. Additionally, safeguarding your pool equipment and plumbing from freezing temperatures and effectively covering your pool ensures that it remains in good condition throughout the winter months.

By following these simple steps, you can keep your pool well-maintained and ready for the next swimming season. Let’s dive into the process of winterizing your inground pool, ensuring it stays protected. It requires minimal effort when it’s time to reopen it in the spring.

Checking and Cleaning Your Pool

Before you start winterizing your pool, the first step is to check and clean it thoroughly. Begin by skimming the surface of the pool to remove any leaves, insects, and debris. This ensures that the water is as clean as possible before you close it for the winter. Follow up by vacuuming the pool floor to remove any dirt that may have settled at the bottom.

Next, clean your pool walls using a brush designed for your pool’s surface material. This helps prevent algae and grime from becoming a problem while the pool is covered. Don’t forget to clean out the skimmer and pump baskets. Ensuring that these components are free of debris is essential for proper water flow and filtration. Finally, check that your pool filter is clean. Whether it’s a sand, cartridge, or DE filter, cleaning it will help your pool remain in good condition during the winter months.

Balancing Your Water Chemistry

Once your pool is clean, the next step is to balance the water chemistry. This is crucial for preventing damage to the pool surfaces and equipment. Start by testing the pH levels with a pool testing kit. The ideal pH level should be between 7.2 and 7.6. Adjust the pH as needed using pH increasers or reducers.

Next, check the alkalinity and calcium hardness levels. The alkalinity should be between 80 and 120 parts per million (ppm), and calcium hardness should be between 200 and 400 ppm. Balancing these levels helps prevent corrosion and scaling. Lastly, add a winterizing chemical kit to your pool. These kits usually include algaecides, stain inhibitors, and floating chlorine dispensers. Following the instructions on the kit will keep your pool water safe and clear throughout the winter.

Protecting Pool Equipment and Plumbing

One crucial step in winterizing your pool is protecting the pool equipment and plumbing. First, you need to drain the water from all pool equipment, including the pump, filter, heater, and chlorinator. Leaving water in these components can cause severe damage if it freezes, leading to costly repairs or replacements. Make sure to follow your manufacturer’s guidelines for draining each piece of equipment.

After draining, use a shop vac or air compressor to blow out any remaining water from the plumbing lines. This helps prevent freezing and cracking during the cold months. Don’t forget to add pool antifreeze to the lines for an extra layer of protection. Finally, remove and store all detachable parts, such as skimmer baskets and hoses, in a dry and safe location. Covering your pool pump and heater with a weatherproof cover will also protect them from the winter elements.

Covering Your Pool for Winter

Covering your pool properly is the final step in preparing your pool for winter. A good pool cover will keep out debris, prevent algae growth, and improve safety by keeping animals and children out of the pool. First, make sure the pool cover you choose fits your pool well. There are different types of covers, including solid covers and mesh covers, each offering different benefits.

After selecting the right cover, spread it carefully over the pool, making sure it is taut and securely fastened. Use water bags or cover weights to hold it in place and prevent it from blowing away in strong winds. Check the cover periodically throughout the winter to ensure it remains secure and free from damage. Regular maintenance of the cover will ensure that your pool remains protected all season long, making spring opening much smoother.


Winterizing your inground pool may seem daunting, but following these steps will ensure your pool stays in excellent condition throughout the colder months. From checking and cleaning to balancing the water chemistry, protecting equipment, and securely covering your pool, each step plays a crucial role in maintaining your pool’s health and longevity. By taking the time to winterize properly, you’ll save yourself from potential damages and costly repairs, making it easier to enjoy your pool when the warmer weather returns.
