As the warm summer months come to an end and the temperature begins to drop, it’s time to start thinking about preparing your pool for winter. Properly winterizing your pool is essential to prevent damage, reduce maintenance costs, and ensure that your pool is ready for use when the weather warms up again. Whether you’re a seasoned pool owner or preparing for your first winter with a pool, these essential tips will guide you through the process of winterizing your pool effectively.

Balance Your Pool’s Water Chemistry

Before closing your pool for the winter, it’s crucial to balance the water chemistry. Properly balanced water helps protect your pool’s surfaces and equipment from corrosion, scaling, and staining during the off-season.

pH, Alkalinity, and Calcium Hardness: Start by adjusting the pH level to between 7.2 and 7.6 to prevent corrosion and scaling. Ensure the total alkalinity is within 80 to 120 parts per million (ppm) to stabilize pH levels. Finally, maintain calcium hardness between 200 and 400 ppm to protect your pool surfaces from etching or scaling.

Shocking the Pool: After balancing the water, shock the pool to eliminate any remaining bacteria and contaminants. This step helps keep the water clear and prevents algae growth over the winter months.

Clean the Pool Thoroughly

A thorough cleaning before winter is critical to prevent debris from causing stains, clogging the filtration system, or leading to algae growth.

Skimming, Vacuuming, and Brushing: Start by skimming the surface to remove leaves and debris, followed by vacuuming the pool floor and walls. Pay attention to corners and steps where debris often accumulates. After vacuuming, brush the pool walls and floor to remove any dirt or algae that could cause damage during the winter.

Filter Cleaning: Once the pool is clean, backwash or clean the filter to remove trapped debris. This step ensures the filter is free of contaminants and ready for the next season. If the filter hasn’t been cleaned recently, consider a deep clean using a filter cleaner.

Lower the Water Level

Lowering the water level in your pool is necessary to prevent damage from freezing water. The exact level to which you lower the water depends on the type of pool and the winter cover you use.

Inground Pools: For standard winter covers, lower the water level 4 to 6 inches below the skimmer. If you’re using a safety cover, lower the water 12 to 18 inches below the skimmer to allow for water displacement when the cover is in place.

Above-Ground Pools: Lower the water level just below the skimmer opening, but avoid draining too much to prevent the pool walls from collapsing. Consider using a skimmer guard to protect the skimmer from freezing water.

Drain and Winterize Pool Equipment

Draining and winterizing your pool equipment is one of the most critical steps in protecting it from freeze damage during the winter months.

Pump, Filter, and Heater: Disconnect and drain the pool pump, remove the drain plugs, and store the pump in a dry, protected area. For sand filters, set them to “winterize” mode or remove the drain plug to drain the water. For cartridge and DE filters, remove and clean the filter elements, and store them indoors. Drain your pool heater by removing the drain plugs and blowing out any remaining water from the lines.

Pool Plumbing and Accessories: Use an air compressor to blow out the water from the pool plumbing lines to prevent freezing and cracking. After blowing out the lines, add pool antifreeze to the plumbing lines as an extra precaution. Remove and store accessories such as ladders, rails, and diving boards, and clean and store automatic pool cleaners indoors.

Cover the Pool

Covering your pool is the final step in the winterization process. A proper winter cover protects your pool from debris, prevents algae growth, and helps maintain the chemical balance over the winter.

Choosing the Right Cover: Standard winter covers are typically made of a heavy-duty tarp material and are secured with water bags or weights. Safety covers are made of strong, mesh material that supports the weight of snow and debris, while allowing water to drain through. If your pool is equipped with an automatic cover, ensure it is securely closed and locked for the winter.

Installing the Cover: Secure the cover properly to prevent it from blowing off during winter storms. Consider adding a leaf net over your winter cover to make it easier to remove leaves and debris that fall onto the cover, reducing the amount of cleaning required in the spring.

Monitor Your Pool Throughout the Winter

Even after you’ve winterized your pool, it’s important to monitor it periodically throughout the winter to ensure everything remains in good condition.

Regular Inspections and Maintenance: Inspect your pool cover regularly to ensure it’s secure and free of damage, and remove any accumulated leaves, snow, or ice from the cover to prevent strain on the pool’s structure. Occasionally check the water level in your pool, and ensure that stored equipment is dry, clean, and safe from pests or other damage.

Properly winterizing your pool is essential for preventing damage and reducing maintenance costs when it’s time to reopen in the spring. By following these essential tips—balancing the water chemistry, thoroughly cleaning the pool, lowering the water level, draining and winterizing equipment, covering the pool, and monitoring it throughout the winter—you can protect your investment and ensure a smooth transition back to swimming season.
