The following sections will detail the specific steps involved, from cleaning and water balancing to equipment removal and covering, providing a comprehensive guide for effectively winterizing your above ground pool.
1. Water Balancing
Water balancing is a critical preparatory step when closing an above ground pool for the winter season. Improperly balanced water can lead to scaling or corrosion during the off-season, resulting in significant damage to the pool liner, walls, and associated equipment. The chemical composition of the water, particularly pH, alkalinity, and calcium hardness, must be within acceptable ranges to prevent these issues. For example, if the pH is too low, the water becomes acidic and can corrode metal components. Conversely, if the pH is too high, calcium can precipitate out of the water and form scale on the pool surfaces. The effect is the degradation of the pool’s infrastructure and reduced lifespan.
Achieving proper water balance before closure involves testing the water using a reliable test kit and adjusting the levels with appropriate chemicals. The specific chemicals used and the quantities required will depend on the initial water chemistry. For instance, if the alkalinity is low, an alkalinity increaser, such as sodium bicarbonate, should be added. This ensures that the pH remains stable. Similarly, if the calcium hardness is low, calcium chloride can be used to increase the calcium level. Regular monitoring and adjustment of these parameters are crucial to creating a stable environment that minimizes the risk of damage during the colder months. A real-world illustration is a pool left with imbalanced water over winter, resulting in extensive liner staining and requiring costly chemical treatments in the spring to rectify the issues.
In summary, water balancing is not merely a preliminary task, but rather a fundamental aspect of winterizing an above ground pool. It addresses the potential for chemical imbalances to cause significant damage, and its proper execution is essential for ensuring the pool’s continued functionality and aesthetic appeal. Overlooking this aspect can lead to preventable problems and additional expense, underscoring the need for meticulous attention to water chemistry during the closure process.
2. Pool Cleaning
Pool cleaning is an indispensable element of how to close above ground pool for the winter season. The accumulation of organic matter, such as leaves, algae, and debris, within the pool water provides a breeding ground for bacteria and can lead to significant staining and discoloration of the pool liner. Furthermore, decaying organic material consumes chlorine, reducing the effectiveness of winterizing chemicals intended to inhibit algae growth throughout the dormant months. A failure to thoroughly clean the pool before closing it will invariably result in a more arduous and costly pool opening process in the spring.
The cleaning process necessitates several distinct actions. First, physical debris should be removed using a leaf net or skimmer. Next, the pool walls and floor must be brushed to dislodge any attached algae or dirt. Finally, a thorough vacuuming is essential to remove all remaining particulate matter from the pool. For example, imagine a pool where leaves have settled on the bottom and remained unaddressed throughout the winter. The decomposition of these leaves will not only stain the pool liner but will also create an environment conducive to algae proliferation, requiring extensive chemical treatment in the spring to restore the water clarity. In practical terms, neglecting this phase essentially guarantees increased maintenance and expense when reopening the pool.
In summation, pool cleaning represents a crucial component of preparing an above ground pool for winter. Its importance resides in mitigating the potential for organic material to degrade water quality, stain surfaces, and promote algae growth during the off-season. While seemingly straightforward, this step significantly reduces the challenges and costs associated with reopening the pool, highlighting the practical significance of thorough pool cleaning prior to winter closure.

Hose and Connection Disconnection
Hoses connecting the pump and filter to the pool are also vulnerable to freezing and cracking. These should be disconnected, drained, and stored in a similar manner to the pump and filter. Further, plugs should be used to seal the pool’s inlet and outlet ports after hose removal to prevent water from entering the plumbing system and potentially freezing within the lines. An example scenario is a fractured hose resulting in water loss and equipment inefficiency.
-
Automatic Pool Cleaners
If an automatic pool cleaner is used, it must also be removed from the pool and stored appropriately. Many cleaners have specific storage recommendations outlined in their user manuals. Failure to follow these recommendations can result in damage to the cleaner’s internal components. Consider a robotic cleaner with sensitive electronics; improper storage could lead to corrosion or other damage rendering it unusable.
-
Ladders and Steps
While not susceptible to freezing damage in the same way as mechanical components, ladders and steps should be removed or securely fastened to prevent movement during the winter. This minimizes potential damage to the pool liner or structure from shifting ice or debris. An unsecured ladder blown around by winter winds could scratch or tear the pool liner, for example.
Effectively executing equipment removal as part of preparing how to close above ground pool is paramount for safeguarding valuable components and ensuring a trouble-free pool opening in the spring. This preventative measure minimizes the potential for freeze damage and maintains the functionality of essential pool equipment for years to come.
4. Winterizing Chemicals

For example, a pool left untreated with algaecide might exhibit significant algae growth upon reopening, necessitating extensive cleaning and chemical treatment to restore its condition.
-
Scale Inhibitors
Scale inhibitors, also known as sequestering agents, prevent the deposition of minerals, such as calcium and magnesium, onto pool surfaces. These minerals can precipitate out of the water, forming unsightly scale that is difficult to remove. Scale buildup can also reduce the efficiency of pool equipment and lead to premature wear. A pool without a scale inhibitor might exhibit a white, chalky residue on the liner and equipment, indicating scale formation that requires chemical or physical removal.
-
Clarifiers
Clarifiers act to bind together small particles suspended in the water, making them large enough to be filtered out or settle to the bottom of the pool for vacuuming. This results in clearer water that is less prone to cloudiness or discoloration. While the pool is covered for the winter, the clarifier helps maintain water clarity, preventing the accumulation of fine debris that can stain or cloud the water. A pool treated with a clarifier is more likely to have visibly cleaner water when the cover is removed in the spring.
-
Non-Chlorine Shock Treatments
While chlorine is often used as a sanitizer, non-chlorine shock treatments can be beneficial when closing a pool. These treatments oxidize organic contaminants, breaking them down and preventing them from contributing to algae growth or water discoloration. They offer an alternative to chlorine, particularly for those sensitive to chlorine’s odor or effects. Using a non-chlorine shock before covering the pool helps eliminate existing organic matter, creating a cleaner environment for the winter months.

-
Debris Prevention
A properly installed cover prevents leaves, branches, and other detritus from entering the pool. The accumulation of organic matter in the water fosters algae growth and can stain the pool liner. Effective cover installation minimizes the need for extensive cleaning and chemical treatment upon reopening. For instance, without a cover, a pool can become filled with decaying leaves, resulting in significant staining and water contamination that requires considerable effort to rectify.
-
Sunlight Reduction
Sunlight promotes algae growth, even in cold water. An opaque cover blocks sunlight, inhibiting photosynthesis and reducing the potential for algae blooms. This preventative measure lessens the reliance on algaecides and contributes to improved water clarity. A transparent cover, conversely, would allow sunlight penetration, potentially fostering algae proliferation despite the cold.
-
Structural Protection
A well-secured cover helps distribute the weight of accumulated snow and ice, minimizing stress on the pool walls. The cover also prevents wind from affecting the water surface, reducing the risk of liner damage from wave action. In regions with heavy snowfall, a cover with sufficient strength and support is essential to prevent the pool walls from buckling or collapsing under the weight.

6. Draining Procedures
Draining procedures are a critical, yet often misunderstood, element when considering how to close above ground pool for the winter months. The extent and method of draining directly impact the structural integrity of the pool and the ease of reopening it in the spring. Improper draining can lead to liner damage, wall collapse, or exacerbated chemical imbalances, all of which increase the time and expense associated with pool maintenance. For example, completely emptying an above ground pool can cause the liner to shrink and crack, especially if exposed to direct sunlight. This shrinkage necessitates costly liner replacement. In contrast, neglecting to drain the pool sufficiently can result in excessive ice expansion, placing undue stress on the pool walls and potentially causing them to buckle.
The general consensus advocates for partially draining the pool, typically to a level just below the skimmer or return jet. This approach reduces the volume of water subject to freezing, thereby minimizing the risk of structural damage, while simultaneously maintaining sufficient water weight to support the liner and prevent shrinkage. Prior to initiating the draining process, one must carefully assess local climate conditions and the pool’s specific construction. Pools situated in regions with exceptionally harsh winters may require a slightly lower water level than those in more temperate zones. Furthermore, the presence of a hard-bottom pool base versus a sand base influences the support provided to the liner during drainage. Failure to consider these factors can lead to adverse outcomes, such as liner displacement or structural instability. For instance, a pool with a sand base and insufficient water weight during the winter may experience significant settling or shifting of the base material, resulting in an uneven pool floor.
In summary, draining procedures represent a nuanced aspect of properly preparing an above ground pool for winter. The objective is to strike a balance between reducing the risk of ice damage and maintaining adequate support for the pool structure. Thoughtful consideration of climate conditions, pool construction, and the potential consequences of improper draining is paramount. Adhering to established best practices for partial draining minimizes the likelihood of damage and streamlines the pool reopening process, thereby demonstrating the practical significance of understanding and correctly implementing draining procedures as an integral component of how to close above ground pool.

The primary objective of plumbing protection is the complete removal of water from all pipes and equipment. This involves disconnecting hoses, opening drain plugs on pumps and filters, and using air blowers or vacuums to force out any remaining water. For instance, failing to evacuate water from a filter pump housing can result in a cracked casing due to ice expansion, necessitating a complete pump replacement in the spring.
-
Antifreeze Application
In certain situations, particularly in regions with exceptionally harsh winters, the application of non-toxic, pool-grade antifreeze is recommended. This antifreeze is poured into the plumbing lines to displace any residual water and provide an additional layer of protection against freezing. However, it is imperative to use antifreeze specifically designed for pools, as automotive antifreeze can be toxic and damaging to pool components. An example of its appropriate use would be in complex plumbing configurations with numerous bends and angles where complete water removal is challenging.
-
Sealing Openings
Once the plumbing system has been drained and treated with antifreeze (if applicable), all openings, including skimmer lines and return jets, should be sealed with expansion plugs or rubber stoppers. This prevents water from re-entering the system and freezing. For example, a loose skimmer plug can allow meltwater to seep back into the lines, potentially freezing and causing cracks near the skimmer opening.
-
Valve Positioning
If the pool plumbing system incorporates valves, they should be positioned in a manner that allows for drainage and prevents water from becoming trapped. Typically, this involves opening or partially opening the valves to ensure a continuous path for water to escape. The positioning varies depending on the design, the goal is to make sure water can escape and to avoid creating pockets in the plumbing system.
In conclusion, effective plumbing protection is an indispensable aspect of how to close above ground pool, safeguarding critical components from freeze damage.
