Every homeowner with an above ground pool faces the challenge of preparing it for winter. Knowing how to winterize an above ground pool can save you time and money come spring, and ensure your pool remains in excellent condition for years to come.

In this comprehensive guide, we delve into the important steps and technologies available to properly winterize your above ground pool, so you can relax and be delighted its protected year-round.

Why Winterizing Your Above Ground Pool is Crucial?

Winterizing your pool is essential to prevent damage from freezing water, which can be very costly to repair. Proper winterization also ensures that the water quality remains adequate, reducing the effort needed to reopen the pool when the weather warms up.

Essential Tools and Supplies for Winterizing

Chemical Testing Kit

A chemical testing kit helps you measure and balance the water’s pH and alkalinity levels before closing the pool.

Pool Cover

A durable cover to keep debris out and prevent algae growth. A fitted cover also helps minimize disturbances due to winds and weather.

Winterizing Chemicals

Specialized winterizing chemicals such as pool shock and algaecide are necessary to keep the water clean and free of contaminants over the winter.

Air Pillow

An air pillow keeps the cover in place and absorbs the pressure of expanding ice, protecting your pool walls.

Step-by-Step Guide to Winterizing Your Pool

Step 1: Clean the Pool Thoroughly

Start by cleaning the pool collecting any leaves, debris, and bugs. Use a pool vacuum or net for better results. Ensure that your pool’s walls and floors are scrubbed clean as well.

Step 2: Test and Balance the Water

Use your chemical testing kit to test the water. Adjust the pH to between 7.2 and 7.6, and make sure the total alkalinity is between 80 and 120 ppm (parts per million). A well-balanced pool prevents corrosion or scaling over the winter season.

Step 3: Super Chlorinate the Water

Add a pool shock to the water 24-48 hours prior to closing your pool. This kills bacteria and prevents algae growth.

Step 4: Add Winterizing Chemicals

After shocking the pool, add specialized winterizing chemicals such as algaecide. These will keep bacteria and algae at bay while the pool is covered.

Step 5: Lower the Water Level

Lower the water level to roughly 4-6 inches below the skimmer. This prevents water from entering and freezing in the skimmer, which could cause damage.

Step 6: Drain and Store Accessories

Make sure to drain all pool equipment such as the pump, heater, and hoses. Store them in a dry, safe place to avoid any damage due to freezing temperatures.

Step 7: Install the Air Pillow

Place the air pillow in the center of the pool. This helps keep the cover in place and absorbs pressure from expanding ice.

Step 8: Cover the Pool

Secure the pool cover over the pool, ensuring it’s tight and free of any gaps. The cover prevents debris from entering and contaminating the water, keeping it relatively clean over the winter.

Common Mistakes to Avoid

Avoiding common mistakes is critical for effective pool winterization:

Skipping the Cleaning Process

Never skip cleaning the pool before winterizing it. Debris left in the pool can cause staining and make the reopening process much more complicated.

Ignoring Water Chemistry

Failing to balance the water correctly can lead to algae growth and other complications. Always ensure the pH and alkalinity levels are well-adjusted.

Not Lowering the Water Level Enough

Make sure to lower the water level correctly to avoid damage from ice and freezing temperatures.

Innovative Technology for Winterizing Pools

Several advancements in pool technology can assist in the winterization process:

Automated Pool Covers

New, automated pool covers can be controlled via smartphone apps, allowing for seamless and secure covering of your pool.

Advanced Chemical Dispensers

Automatic chemical dispensers can ensure your pool’s water chemistry remains balanced throughout the winter, reducing maintenance efforts.

Benefits of Proper Winterization

Proper winterization can extend the lifespan of your pool and reduce the need for costly repairs. It also ensures that reopening your pool in the spring is a smooth process.

Protects Pool Structure

A winterized pool is less exposed to the elements, reducing the risk of structural damage caused by freezing and thawing cycles.

Maintains Water Quality

By keeping the water clean and balanced, winterization makes it easier and quicker to get your pool swim-ready at the beginning of the summer.

Frequently Asked Questions (FAQs)

What if I forget to winterize my above ground pool?

If you forget to winterize your pool, you risk damaging the pool structure and equipment due to freezing and accumulated debris. Proper winterization helps avoid costly repairs and prolonged maintenance tasks.

Can I use a regular pool cover instead of a winter cover?

Winter covers are specifically designed to handle the weight of snow and ice. Using a regular pool cover may not provide sufficient protection and can result in damage.

Is it necessary to use an air pillow?

Using an air pillow helps distribute the weight of the ice and prevents pressure on the pool walls, reducing the risk of damage. It’s highly recommended for effective winterization.
