The process of preparing a specific type of swimming pool for the off-season involves a series of steps designed to protect the pool’s structure and equipment from damage caused by freezing temperatures and inactivity. This procedure typically includes cleaning, balancing water chemistry, adding winterizing chemicals, and physically covering the pool to prevent debris accumulation. For example, draining water to below the skimmer, disconnecting hoses, and installing a winter cover are common steps.
Undertaking this task properly can significantly extend the lifespan of the pool liner and equipment, reducing the likelihood of costly repairs in the spring. Furthermore, it helps to prevent algae growth and keeps the water cleaner, making the spring opening process much easier and less time-consuming. Historically, these preparations have evolved from simple draining and covering to more sophisticated chemical treatments and cover technologies designed to maximize protection.
Following a systematic approach to off-season pool care is essential. The subsequent sections will outline specific steps, including water testing and treatment, equipment preparation, and proper cover installation to ensure effective protection throughout the winter months.
1. Water chemistry balance
Maintaining proper water chemistry balance is a fundamental step when preparing an above ground pool for winter. Imbalances can lead to significant problems during the off-season, regardless of other preventative measures taken. Specifically, pH levels, alkalinity, and calcium hardness must be within recommended ranges before winterizing chemicals are added. Failure to balance the water can result in scaling on pool surfaces due to high calcium levels or corrosion of metal components due to low pH levels. For instance, if the pH is too low, it can corrode the pool’s metal supports and plumbing, leading to structural damage. If the pH is too high, it can cause calcium to precipitate out of solution, forming unsightly scale on the liner and reducing the efficiency of winterizing chemicals.
The ideal ranges for these parameters are typically pH between 7.2 and 7.6, alkalinity between 80 and 120 ppm, and calcium hardness between 200 and 400 ppm. Correcting imbalances involves using appropriate chemicals such as pH increaser (soda ash), pH decreaser (muriatic acid or sodium bisulfate), alkalinity increaser (sodium bicarbonate), or calcium chloride. Testing kits, either liquid or strip-based, are used to accurately measure these levels, and adjustments are made accordingly. Neglecting this process can negate the effectiveness of other winterizing steps, potentially leading to more extensive repairs come spring.
In summary, achieving water chemistry balance is not merely a preliminary step; it is an integral component of the winterization procedure. Addressing these parameters proactively minimizes the risk of damage and simplifies the pool opening process in the subsequent season. Ignoring proper balance can result in costly repairs and increased maintenance time, highlighting the practical significance of this often-overlooked aspect of pool winterization.
2. Equipment draining
Thorough draining of pool equipment is a critical step in preparing an above ground pool for the winter season. This process safeguards vital components from potential damage caused by freezing water, ensuring their functionality and longevity.
-
Pump Housing and Impeller
The pump housing must be completely drained to prevent cracking due to ice expansion. Removing the drain plugs, typically located at the base of the pump housing, allows water to evacuate. Furthermore, disconnecting hoses and physically removing the impellerif easily accessibleprovides an added measure of protection against residual water accumulation and subsequent freezing damage. Failure to properly drain the pump can lead to costly pump replacement in the spring.
-
Filter System (Sand or Cartridge)
Sand filters require backwashing and draining. Opening the drain port at the bottom of the filter tank allows water to escape. For cartridge filters, the cartridge should be removed, cleaned thoroughly, and stored in a dry place. Draining the filter housing itself is equally important. Residual water in either type of filter can freeze, potentially cracking the tank or damaging internal components.
-
Heater (If Applicable)
Pool heaters, if present, are particularly vulnerable to freeze damage due to their complex internal plumbing. Manufacturers often provide specific draining instructions. Typically, this involves disconnecting water lines and opening drain valves. Blowing air through the heater’s plumbing lines can further ensure complete water removal. Ignoring this step can result in significant heater damage and expensive repairs.
-
Piping and Plumbing
Disconnecting all hoses and sections of exposed piping is essential. Any water trapped in these lines can freeze and cause cracks or breaks. Storing the disconnected components indoors prevents them from becoming brittle or damaged by the elements. Utilizing a shop vacuum or air compressor to blow out residual water from the plumbing lines offers added protection against freezing.
In conclusion, meticulous draining of all above ground pool equipment is a non-negotiable step in the winterization process. Neglecting this aspect can lead to significant and costly repairs, whereas a thorough and proactive approach ensures the equipment remains in good working order, ready for the next swimming season.

-
Algaecides
Winter algaecides are formulated to prevent the proliferation of algae during the off-season. Unlike standard algaecides, these compounds are typically more concentrated and effective in colder temperatures. Without algaecides, algae blooms can stain pool surfaces and lead to significant cleaning challenges in the spring. A common example involves the use of polyquaternary ammonium algaecides, which inhibit algae growth without causing excessive foaming.
-
Scale Inhibitors
Scale inhibitors, such as sequestering agents, are deployed to prevent the formation of mineral deposits on pool surfaces. During winter, minerals in the water can precipitate out of solution, leading to scale buildup. These inhibitors keep minerals dissolved, thereby preventing scaling. Examples include compounds based on phosphonic acid derivatives, which bind to calcium and magnesium ions, preventing them from forming scale.
-
Non-Chlorine Shock Treatments
Non-chlorine shock treatments, typically based on potassium monopersulfate, oxidize organic contaminants in the water. This reduces the demand for chlorine in the spring and helps to maintain water clarity. Unlike chlorine-based shocks, these treatments do not increase chlorine levels, minimizing the risk of bleaching or damage to pool liners. They effectively break down oils, lotions, and other organic matter that can accumulate in the pool water.
-
Winterizing Kits
Many manufacturers offer pre-packaged winterizing kits that contain a combination of the aforementioned chemicals, often tailored to specific pool sizes. These kits simplify the process by providing pre-measured doses of each chemical, reducing the likelihood of errors in application. These often include algaecides, scale inhibitors, and non-chlorine shock treatments in appropriate ratios, providing a convenient and comprehensive solution for winter pool care.
In summary, the strategic use of winterizing chemicals is essential for preserving the integrity of an above ground pool during the colder months. These compounds work synergistically to prevent algae growth, inhibit scale formation, and oxidize organic contaminants, thereby simplifying the spring opening process and extending the lifespan of pool components. Their application represents a proactive approach to pool maintenance, mitigating potential problems before they arise.
4. Cover installation
Proper cover installation is a linchpin in the effective winterization of an above ground pool. This protective barrier shields the pool from debris, reduces sunlight exposure, and helps to maintain water chemistry throughout the off-season. A poorly installed cover can negate other winterization efforts, leading to increased maintenance and potential damage.
-
Material Selection and Durability
The choice of cover material directly impacts its ability to withstand winter conditions. Options range from basic polyethylene covers to more robust vinyl or reinforced materials. Thicker, more durable covers are less prone to tearing or damage from snow and ice accumulation. For instance, a reinforced vinyl cover can withstand significantly heavier loads than a standard polyethylene cover, reducing the risk of collapse and subsequent debris contamination.
-
Secure Attachment Mechanisms
The method of securing the cover to the pool is crucial for preventing wind uplift and ensuring a tight seal. Common attachment methods include cable and winch systems, overlap and clip designs, and water tubes. A properly secured cover minimizes the entry of leaves, branches, and other debris, which can decompose and negatively affect water quality. Cable and winch systems, when properly tightened, distribute the load evenly around the pool’s perimeter, preventing localized stress points.
-
Cover Size and Overlap
The cover must be appropriately sized to provide adequate overlap beyond the pool’s edges. Insufficient overlap can lead to gaps through which debris can enter. An ideal overlap typically ranges from three to four feet, allowing for secure attachment and preventing the cover from being pulled into the pool during strong winds. This ensures comprehensive protection and minimizes the risk of contamination.
-
Water Level Management
Maintaining an appropriate water level below the skimmer during cover installation is essential. This prevents excessive pressure on the cover and pool walls, particularly during periods of heavy precipitation. Draining the water to the correct level helps to support the cover and distribute the weight of snow and ice evenly. Overfilling can cause the cover to sag and potentially damage the pool structure.
In summary, careful consideration of material durability, secure attachment, appropriate sizing, and water level management are all integral to effective cover installation. These factors, when properly addressed, contribute significantly to the overall success of the winterization process, ensuring that the pool remains protected and ready for use in the spring. Neglecting these aspects can compromise the cover’s effectiveness and lead to increased maintenance requirements.
5. Pool cleaning
Pool cleaning, specifically the thorough removal of debris and contaminants, is a prerequisite for successful above ground pool closure. Organic matter left in the pool during winter decomposes, fostering algae growth and staining surfaces. This necessitates more intensive cleaning efforts in the spring and potentially shortens the lifespan of the pool liner. For instance, neglecting to remove leaves and twigs prior to covering the pool can result in a murky, contaminated pool come spring, requiring extensive chemical treatment and labor to restore it to a usable condition. The cause-and-effect relationship is clear: inadequate pre-winter cleaning directly increases post-winter maintenance demands.
The act of pool cleaning prior to closure also allows for a more accurate assessment of the pool’s condition and the effectiveness of winterizing chemicals. Removing all visible debris enables a comprehensive inspection of the liner for any signs of wear or damage that may require attention. Furthermore, clean water allows winterizing chemicals to function more effectively, as they are not competing with organic matter for efficacy. A practical example involves a pool owner who meticulously cleans their pool before winterizing and experiences minimal algae growth and clear water in the spring, demonstrating the tangible benefits of this approach. Conversely, a pool that is closed without proper cleaning may harbor algae and bacteria, diminishing the impact of the winterizing chemicals.
In conclusion, pool cleaning is not merely a preliminary step but an integral component of the overall winterization process. It directly influences the ease of spring opening, the longevity of pool components, and the effectiveness of winterizing chemicals. Addressing this aspect proactively minimizes the potential for problems and ensures a smoother transition back to recreational use. Overlooking the importance of pre-winter cleaning creates a cascade of negative consequences, underscoring the practical significance of prioritizing this task.
6. Skimmer protection
The safeguarding of the skimmer unit is a critical consideration when preparing an above ground pool for winter. The skimmer, responsible for removing surface debris, is vulnerable to damage from freezing water and ice expansion. Protecting this component prevents costly repairs and ensures its functionality for the following swimming season. Proper skimmer protection methods are therefore integral to successful pool winterization.
-
Skimmer Plate or Plug Installation
Installing a dedicated skimmer plate or plug serves as a primary barrier against water entry and ice formation within the skimmer housing. These devices effectively seal off the skimmer opening, preventing water from entering and freezing. For example, a threaded plug can be screwed into the skimmer’s plumbing to create a watertight seal, or a custom-fitted plate can be secured over the skimmer opening with screws or clips. This prevents damage to the skimmer body and connected plumbing caused by expanding ice.
-
Gizzmo Usage
A “Gizzmo” is a specialized, elongated device designed to absorb ice expansion within the skimmer. This typically involves a hollow plastic cylinder with threads that screw into the skimmer’s bottom opening. Its internal chamber accommodates ice expansion, preventing the skimmer walls from cracking. The Gizzmo acts as a sacrificial element, absorbing the pressure that would otherwise damage the skimmer. One example is a threaded Gizzmo filled partially with antifreeze for added protection.
-
Antifreeze Application (If Necessary)
In regions experiencing extremely low temperatures, the use of pool-grade antifreeze within the skimmer and connected plumbing offers an additional layer of protection. Antifreeze lowers the freezing point of any residual water, preventing it from solidifying and causing damage. Specifically, non-toxic propylene glycol antifreeze is used, ensuring it does not contaminate the pool water upon spring opening. Antifreeze should be carefully poured into the skimmer after other protection measures are in place to further mitigate freezing risks.
-
Disconnecting and Plugging Plumbing Lines
As part of the overall winterization process, disconnecting the plumbing lines connected to the skimmer and sealing them with appropriate plugs is essential. This prevents water from migrating into the skimmer from other parts of the pool system and subsequently freezing. A common approach involves using rubber expansion plugs to create a watertight seal within the disconnected pipes, preventing water intrusion and protecting the plumbing from freeze damage. Disconnecting and plugging these lines contributes to the overall effectiveness of skimmer protection.
In conclusion, safeguarding the skimmer through a combination of physical barriers, expansion absorption, and chemical protection is vital for successfully preparing an above ground pool for the winter months. These strategies work in concert to prevent freeze damage, ensuring the skimmer remains functional and ready for use when the pool is reopened. Neglecting skimmer protection can lead to costly repairs and unnecessary complications in the spring, highlighting the importance of this step in the broader context of pool winterization.
7. Freeze plugs
Freeze plugs are essential components in the procedure of preparing an above ground pool for the winter season. Their primary function is to protect the pool’s plumbing system from damage caused by the expansion of freezing water. Understanding their application and proper installation is crucial for successful pool winterization.
-
Function and Placement
Freeze plugs, typically made of rubber or plastic, are inserted into the openings of skimmers, returns, and other plumbing connections to prevent water from entering and subsequently freezing within the pipes. Their placement is critical, as they must create a watertight seal to effectively block water intrusion. For example, inserting a freeze plug into the skimmer’s bottom opening after disconnecting the plumbing line prevents water from accumulating and freezing in the skimmer’s underground pipe, potentially cracking the pipe and causing significant damage. Failure to properly install these plugs can result in costly plumbing repairs in the spring.
-
Types of Freeze Plugs
Various types of freeze plugs are available, each designed for specific applications. Rubber expansion plugs, for instance, feature a wing nut that, when tightened, expands the rubber to create a secure seal. These are commonly used in skimmer openings and return lines. Threaded plugs, on the other hand, are screwed into threaded fittings to provide a watertight closure. The choice of plug depends on the type of fitting and the required level of sealing. For example, a threaded plug may be preferred for a more permanent and secure seal in a filter or pump housing drain, while a rubber expansion plug may be more suitable for a skimmer opening that needs to be easily accessible.
-
Importance of Proper Sizing
Selecting the correct size of freeze plug is paramount for ensuring a watertight seal. A plug that is too small will not create a sufficient seal, allowing water to seep into the plumbing and freeze. A plug that is too large may be difficult to install or may damage the fitting. Accurate measurement of the opening is therefore essential before selecting a freeze plug. A practical example involves measuring the internal diameter of a skimmer pipe before purchasing a rubber expansion plug to ensure a snug and effective fit. Using the wrong size plug negates its protective function and exposes the plumbing to freeze damage.
-
Integration with Other Winterization Steps
Freeze plugs are most effective when used in conjunction with other winterization measures, such as draining the plumbing lines and applying antifreeze. While freeze plugs prevent water from entering the plumbing, residual water may still be present. Draining the lines removes most of this water, and antifreeze lowers the freezing point of any remaining water, further minimizing the risk of freeze damage. For instance, after installing freeze plugs in the skimmer and return lines, blowing out the pipes with an air compressor and adding pool-grade antifreeze provides comprehensive protection against freezing, especially in regions with harsh winters. The combination of these steps maximizes the effectiveness of freeze plugs and ensures the integrity of the pool’s plumbing system.
In summary, freeze plugs constitute a critical line of defense against freeze damage during the winter months. Their proper selection, installation, and integration with other winterization steps are essential for preserving the pool’s plumbing system and avoiding costly repairs. Neglecting freeze plugs or using them incorrectly undermines the overall winterization effort and increases the risk of damage, highlighting their importance in the comprehensive process of preparing an above ground pool for winter.
