How to Winterize Your Pool: A Step-by-Step Guide
As the swimming season draws to a close and the cool weather begins to settle in, it's time to start thinking about how to prepare your pool for the winter months. Properly closing your pool for the winter is essential to protect it from the elements, prevent damage, and ensure a smooth opening when warmer days return. In this guide, we'll walk you through the key steps to winterize your pool effectively.
Do You Need to Winterize Your Inground Pool?
Before diving into the winterization process, it's important to note that not all pools need to be closed for the winter. In fact, if you have an inground pool, we recommend keeping it open throughout the winter. With the proper maintenance and care, inground pools can remain functional during the colder months, allowing you to avoid the hassle of reopening in the spring. Keeping your pool open also helps to prevent problems like algae growth and stagnant water, making it a better option for many pool owners.
For those with above-ground pools or who prefer to close their pool for the season, the following steps will guide you through the winterization process.
Step 1: Clean the Pool Thoroughly
Before you begin the winterization process, it's essential to start with a clean pool. Skim the surface to remove any leaves, debris, or insects, and then vacuum the pool floor to get rid of dirt and algae. Make sure to clean out the skimmer baskets and scrub the pool walls to prevent algae buildup over the winter.
Step 2: Balance the Water Chemistry
Once your pool is clean, the next step is to balance the water chemistry. Proper water balance helps protect the pool’s surfaces and equipment during the winter. Here's what you need to do:
pH level: Aim for a pH between 7.2 and 7.6.
Total Alkalinity: Should be between 80 and 120 ppm.
Calcium Hardness: Target 180 to 220 ppm.
After adjusting these levels, it’s also wise to add a winterizing chemical kit, which typically includes a shock treatment, algaecide, and a stain prevention treatment. These chemicals will help keep the water clear and prevent staining and algae growth over the winter months.
Step 3: Lower the Water Level
Next, lower the water level in your pool to prepare it for winter. This step is crucial to prevent freezing and expansion from causing damage to the pool and its components. The ideal water level depends on the type of pool cover you plan to use:
Solid Cover: Lower the water level to about 4-6 inches below the skimmer.
Mesh Cover: Lower the water level to about 12-18 inches below the skimmer.
Lowering the water level prevents water from entering the skimmer, which could freeze and crack the skimmer or plumbing lines.
Step 4: Drain and Store Pool Equipment
It’s important to drain and store your pool equipment to protect it from freezing temperatures. Follow these steps:
Pump and Filter: Drain all the water from your pool pump, filter, heater, and chlorinator. Remove the drain plugs and allow the equipment to dry before storing it in a dry, frost-free location.
Hoses and Lines: Blow out the water from the plumbing lines using a shop vac or air compressor. This step is crucial for preventing freeze damage to the pipes. After blowing out the lines, seal them with expansion plugs.
Accessories: Remove and store pool accessories like ladders, skimmer baskets, and diving boards in a dry place.
Step 5: Cover the Pool
Once your pool is clean, balanced, and equipment-free, the final step is to cover it properly. A high-quality pool cover is essential for keeping out debris, protecting the water, and preventing algae growth. Here are your options:
Solid Pool Cover: Provides the best protection against debris and sunlight, which helps prevent algae growth. Make sure to secure the cover tightly to prevent it from blowing off during winter storms.
Mesh Pool Cover: Allows water to pass through but keeps out leaves and large debris. These covers are typically easier to handle and don’t require draining water accumulation over the winter.
If you live in an area with heavy snowfall, consider adding a cover pump to remove excess water from the cover periodically.
Bonus Tips for Winterizing Your Pool
Check your pool cover periodically: Over the winter, it’s a good idea to check on your pool cover occasionally to ensure it’s secure and free of damage.
Keep an eye on water levels: Even with a cover, rain and snow can raise the water level. If it gets too high, consider draining some water to maintain the appropriate level.
Plan for your pool’s reopening: When you’re ready to open your pool in the spring, having a clear plan and the necessary chemicals on hand will make the process much smoother.
Conclusion
Winterizing your pool is a vital task that pays off by protecting your investment and making for an easier opening when warm weather returns. By following these steps—cleaning, balancing water chemistry, lowering water levels, draining equipment, and covering your pool—you’ll ensure that your pool remains in excellent condition throughout the winter months. If you have an inground pool, consider keeping it open during the winter to avoid the complexities of winterization and enjoy a seamless transition into the next swimming season.
