The Importance of Proper Pool Winterization for Above Ground Pools
Taking the time to properly winterize your above ground pool is more than just a chore; it’s a crucial act of preservation. Neglecting this process can lead to significant problems, impacting both your wallet and your pool’s longevity. Think of it as preparing your outdoor gear for storage after a long trip – you clean it, dry it, and pack it away to prevent damage.
Freezing water is the primary enemy. As water freezes, it expands, creating immense pressure. This expansion can crack pipes, damage your skimmer, split your pool liner, and even warp the pool walls. Such damage often requires expensive repairs or even complete pool replacement.
Beyond freeze damage, winterization also prevents the growth of stubborn algae and bacteria. Properly balanced and treated water under a good cover will resist these invaders, saving you hours of scrubbing and chemical treatments when you reopen your pool in the spring. A little effort now saves a lot of hassle later.

How to Winterize Your Above Ground Pool: A Comprehensive Step-by-Step Guide
This detailed guide will walk you through the entire process of preparing your above ground pool for winter. Follow these steps carefully to ensure maximum protection and a smooth spring reopening.
Step 1: Clean and Balance Your Pool Water
Begin the winterization process by giving your pool a thorough cleaning. This is critical for preventing algae growth over the winter.
Start by removing all debris from the water using your skimmer net. Skim leaves, bugs, and any other floating particles.
Next, vacuum the pool floor to remove dirt, sand, and sunken debris. Brush the pool walls and floor to dislodge any clinging algae or grime.
Once clean, test your water chemistry. Adjust pH to 7.2-7.6, alkalinity to 80-120 ppm, and calcium hardness to 180-220 ppm. Proper balance is key to chemical effectiveness.
Step 2: Add Winterizing Chemicals
After cleaning and balancing, it’s time to add your winterizing chemical kit. These chemicals work together to keep the water clear and prevent issues during the off-season.
First, “shock” your pool with a heavy dose of chlorine shock to kill any remaining bacteria and algae. Follow the manufacturer’s instructions for dosage, typically adding it in the evening.
The next day, add a winterizing algaecide. This powerful chemical will prevent algae from blooming while the pool is dormant. Pour it evenly around the pool’s perimeter.
Finally, add a metal sequestrant or stain preventer. This helps prevent mineral stains on your liner during the long winter months. Allow the chemicals to circulate for several hours (or overnight) using your pump.
Step 3: Lower the Water Level
You need to lower your pool’s water level below the skimmer and return jets. This prevents water from entering and freezing in these critical components.
For above ground pools, aim to lower the water level to about 4-6 inches below the skimmer opening and any return jets. You can do this by using your pool’s filter pump on the “waste” or “drain” setting, or by using a submersible pump.
Be mindful of where the drained water goes, especially if you have a septic system or strict local drainage regulations. Avoid flooding your yard or neighbors’ property.
Step 4: Disconnect and Store Equipment
Remove and properly store all removable pool equipment to protect it from freezing temperatures and prolong its life.
Disconnect your pool pump, filter, heater, and any chlorinators. Drain all water from these components thoroughly. Many filters have a drain plug at the bottom.
Clean filter cartridges or backwash sand filters. Store cartridges indoors in a clean, dry place. If you have a sand filter, consider adding a filter winterizing chemical to prevent clumping.
Remove the pool ladder, steps, and handrails. Clean them and store them in a garage or shed. If your pool has a solar cover or leaf net, clean and store them as well.
Step 5: Protect Pipes and Skimmer
Protecting your plumbing is one of the most important steps when you winterize your above ground pool. Freezing water in pipes can cause catastrophic damage.
Blow out your skimmer and return lines using a shop vac or air compressor. This removes all water from the lines. Blow air from the pump connection point back towards the pool.
Once the lines are clear of water, immediately insert a skimmer plug or Gizzmo into the skimmer opening. For return jets, use winterizing return line plugs. This seals off the lines, preventing water from re-entering.
As an extra layer of protection, pour non-toxic pool anti-freeze into the skimmer and return lines after they are plugged. This ensures any residual water cannot freeze and expand.
Step 6: Install the Winter Cover
The final step in preparing your pool for winter is to install the winter cover. This protects the water from debris and sunlight, which can encourage algae growth.
Before installing the cover, place one or more air pillows in the center of the pool. These pillows absorb ice expansion and keep the cover elevated, preventing water from pooling on top.
Carefully unroll your winter cover over the pool. Ensure it extends several feet beyond the pool’s edge on all sides. Secure the cover using a cable and winch system, or cover clips if your pool has a top rail designed for them.
Make sure the cover is taut and secure to prevent wind from dislodging it. A well-secured cover keeps out leaves, dirt, and sunlight, making for a much cleaner pool opening in the spring.
Common Mistakes to Avoid When Winterizing Your Above Ground Pool
Even experienced pool owners can make mistakes. Being aware of common pitfalls can save you time, money, and frustration. Not Cleaning Thoroughly Enough: Leaving debris or algae in the pool provides nutrients for growth over winter, leading to a green swamp in spring. Take your time with cleaning.
Improper Water Chemistry: Skipping the balancing and shocking steps means your winterizing chemicals won’t be as effective. Test and adjust carefully. Forgetting Air Pillows: These are vital for above ground pools. Without them, ice expansion can push against the pool walls, causing structural damage or tearing the liner. Not Draining Equipment Completely: Any water left in pumps, filters, or heaters will freeze and likely crack the components. Always ensure everything is fully drained and disconnected.
Using Automotive Anti-Freeze: Never use automotive anti-freeze in your pool. It’s toxic and designed for engines, not swimming pools. Always use non-toxic, propylene glycol-based pool anti-freeze. Loose Winter Cover: A poorly secured cover can blow off in strong winds, exposing your pool to debris and potentially damaging the cover itself. Double-check your fasteners.
Beyond Winterization: Preparing for Spring Opening
While this guide focuses on how to winterize your above ground pool, thinking ahead to spring can make the entire seasonal cycle smoother.
Keep an eye on your pool throughout the winter. Check the cover periodically, especially after heavy snow or strong winds. Remove excessive snow accumulation from the cover to prevent stressing it.
If you see any issues, address them promptly. A small tear in the cover can become a large problem if left unchecked.
In early spring, before temperatures consistently rise, you can start gathering your spring opening chemicals and supplies. This proactive approach ensures you’re ready to enjoy your pool as soon as the weather warms up.
Frequently Asked Questions About Above Ground Pool Winterization
Preparing your pool for winter often brings up specific questions. Here are some common ones with straightforward answers.
When is the best time to winterize an above ground pool?
The ideal time to winterize your above ground pool is when the daytime temperatures consistently drop below 60°F (15°C) but before freezing temperatures become common. This timing prevents early algae growth while minimizing the chance of an unexpected freeze damaging your system before winterization is complete.
Do I need to completely drain my above ground pool for winter?
No, you should not completely drain your above ground pool for winter. The weight of the water helps support the pool walls against external pressures from snow, ice, and wind. Lowering the water level below the skimmer and return jets (typically 4-6 inches) is sufficient to protect the plumbing.
How many air pillows do I need for my pool?
The number of air pillows depends on your pool’s size. For round pools, one large air pillow (e.g., 4×8 ft for a 24 ft round pool) is often enough. For larger or oval pools, you might need two or more, placed strategically to elevate the center of the cover and distribute ice pressure. Consult your pool cover manufacturer’s recommendations.
Can I use a regular tarp as a winter cover?
While a regular tarp might seem like a budget-friendly option, it’s generally not recommended as a long-term winter cover. Tarps are not designed to withstand the harsh winter elements, UV exposure, or the weight of snow and ice. They can tear easily, letting debris and sunlight into your pool. Invest in a dedicated above ground pool winter cover for optimal protection.
What happens if I don’t winterize my pool?
If you don’t winterize your pool, you risk severe and costly damage. Freezing water can crack your skimmer, plumbing, pump, and filter. The pool liner can split from ice expansion. Additionally, you’ll likely face a massive algae bloom, turning your pool water green and requiring extensive cleaning and chemical treatment in the spring.
