As the colder months approach, it’s time to turn your attention to winterizing your inground pool. Properly winterizing your pool can save you time, money, and effort when you’re ready to enjoy it again in the spring. In this comprehensive guide, we’ll take you through the essential steps to winterize your inground pool, ensuring it remains in excellent condition during the off-season. Follow these steps in sequence for a smooth and hassle-free process.

Step 1 – Remove Pool Accessories

Before you embark on the winterization process, start by removing all pool accessories. This includes skimmer baskets, cleaners, ladders, steps, and solar blankets. By doing so, you prevent potential damage and ensure they’re ready for use when the pool reopens in the spring.

Step 2 – Deep Clean the Pool

To keep your pool in pristine condition throughout the winter, a thorough cleaning is crucial. Begin by using skim nets to remove leaves and debris from the water’s surface. Next, employ a pool vacuum to clear the bottom of the pool. Finish by brushing the pool’s floor and sides. This not only maintains the pool’s aesthetics but also prevents the buildup of algae and other contaminants.

Step 3 – Adjust the Water Chemistry

Maintaining proper water chemistry is vital for the health of your pool. Start by checking and balancing the pH and alkalinity levels. Then, shock the pool to eliminate any lingering bacteria and organic matter. Additionally, consider adding algaecide and winterizing chemicals as needed to prevent algae growth and maintain water clarity throughout the winter.

Step 4 – Lower the Water Level

To safeguard your pool from potential freezing damage, it’s essential to lower the water level below the skimmer. Use a small air compressor or a high-volume blower to remove water from the pool equipment and pipes, ensuring there’s no water left that can freeze and cause damage. Additionally, install pool plugs to block water from re-entering the return lines, and think about using a skimmer guard to protect it from cracking due to ice expansion.

Step 5 – Winterize Pool Plumbing

Properly winterizing your pool plumbing is critical. Start by draining water from the pump, filter, chlorinator, and heater (if you have one). If possible, store your filter and pump indoors. If indoor storage isn’t an option, use a shop vac or an air compressor to remove any remaining water from the equipment. Don’t forget to lubricate valves and o-rings on your equipment to keep them in good condition, ensuring they function properly when you reopen the pool in the spring.

Step 6 – Cover the Pool

With the pool fully winterized, it’s time to protect it from the elements. Use a durable pool cover to shield your pool from debris, snow, and harsh weather conditions. Make sure the cover is clean and dry when you put it in place, and adjust it as needed to keep it secure throughout the winter. A properly fitted pool cover is your best defense against potential damage and will make your spring reopening a breeze.


Properly winterizing your inground pool is a fundamental aspect of pool maintenance. By following these steps in sequence, you ensure that your pool remains in excellent condition throughout the winter months, making it much easier to reopen when the warm weather returns. Keep in mind that some steps may require several days to complete, so plan ahead and allocate the necessary time. By investing the effort now, you’ll be rewarded with a well-maintained and enjoyable pool when the cold season subsides. Winterize your pool with care, and you’ll have peace of mind during the winter months, knowing that your pool is protected and ready for another season of fun in the sun.
