Importance of Using a Pool Cover

Appropriate usage of a pool cover can make an enormous difference for a pool owner. It’s an essential tool that presents multitude benefits, from maintaining water temperature to keeping the pool clean. Alongside, knowing potential problems associated with pool covers lets you take proper precautions.

Benefits of Pool Covers

A pool cover constitutes a crucial part of pool maintenance. It offers benefits such as:

  1. Conserving Water: Pool covers reduce evaporation drastically, saving gallons of water, an important aspect particularly in areas experiencing water scarcity.
  2. Maintaining Temperature: Exposing your pool to the sun’s heat during the day and the cool air at night can cause drastic temperature fluctuations. A pool cover acts as an insulator, conserving the heat absorbed during the day.
  3. Keeping Clean: Debris like leaves, dust, and insects often find their way into a pool. Covering the pool minimizes the entrance of unwelcome items, thereby reducing the need for frequent cleaning.
  4. Chemical Protection: Pool chemicals break down quickly under sunlight, but with a cover, you can shield these chemicals, retaining their effectiveness for longer.

Common Issues with Pool Covers

In as much as a pool cover provides immense advantages, certain frequent issues arise with its usage. Being aware of these allows you to appropriately manage your cover.

  1. Wear and Tear: Pool covers, subjected to harsh weather conditions and sunlight, endure wear quickly. This aging could result in the cover becoming brittle, torn, or saggy.
  2. Sagging Pool Covers: This issue often arises due to poor installation, structural damage, or weight from accumulated debris or water. It’s not only unsightly but also leads to a pool cover not serving its purpose effectively.
  3. Incorrect Size or Shape: A poor fit is a common issue with pool covers. An ill-sized cover fails to appropriately cover the pool, leaving the water exposed to environmental elements.

By comprehending the significant role of a pool cover and understanding the common issues, you can ensure you’re getting the best out of your pool cover while maintaining the aesthetic and function of your pool.

Causes of Pool Cover Sagging

Water Accumulation

One main reason for pool cover sagging can be excessive water accumulation. Typically, pool covers are designed to repel water and other debris, deterring them from entering the pool. However, persistent rainfall can lead to water pooling and causing the cover to sag. Extensive snow accumulation during winter can also have a similar effect. For instance, a foot of fresh snow can weigh around 3 to 7 pounds per square foot, thus exerting pressure on the cover, resulting in sagging.

To prevent this, regular maintenance checks are crucial, especially after harsh weather conditions. Removing snow or standing water from the cover promptly using automated pool cover pumps, for example, can help combat undue stress and prevent sagging.

Incorrect Installation

A case of sagging can also occur due to an incorrect installation. When the pool cover doesn’t perfectly fit the pool dimensions, it tends to sag in certain areas. For example, if a cover designed for a 20 foot pool is installed in a 22 foot structure, the excess pull from the edges may cause the center to sag.

Apart from size, the method of installation plays a significant role too. Ideally, the cover’s edge should sit snugly on the pool rim, creating tension across the entire cover’s length. If the edges are loosely fitted or not anchored properly, the center could sag.

To avoid this, you ought to ensure a precise fit between the pool and its cover, taking accurate pool measurements that include its length, width, and depth. Additionally, during installation, follow manufacturer instructions carefully, making sure to anchor the cover firmly for even distribution of tension. Thus, effective installation contributes significantly to avoiding sagging issues in pool covers.

Preventative Measures to Avoid Sagging

Knowing the causes of pool cover sagging can be a starting step, but it’s more crucial to take proactive measures. Managing this common problem involves two main strategies: choosing the right cover and adhering to regular upkeep.

Choosing the Right Cover

Picking the correct fit contributes majorly in preventing sagging. Size and strength of the pool cover matter immensely.

  1. Accurate Specifications: Selecting an appropriate size cover ensures a snug fit, curbs excess accumulation of water and leaves, and minimizes sagging chances. For instance, if your pool measures 20×40, get a cover that’s meant for this size.
  2. Quality Material: Choosing a durable, strong cover that withstands harsh weather conditions reduces sagging prospects. Pool covers made of vinyl, for instance, offer high durability and resistance to elements.
  3. Anchors, Straps, and Security: Appropriate securing tools ensure a taut fit, eliminating sagging. Look for covers with sturdy anchors and fastening straps.

Regular Maintenance Tips

Keeping your pool cover in good condition is equally pivotal. Routine checking and timely interventions curb sagging potential significantly.

  1. Prompt Cleaning: Clear leaves, water, and snow immediately as they accumulate. By reducing their weight, you prevent your cover from sagging. A cover pump comes in handy for removing water.
  2. Regular Inspection: Periodic check-ups prevent minor issues from escalating into major sag-causing problems. Inspect for wear and tear, and give attention to the attachments and fastenings. A small tear, if not repaired promptly, can expand under heavy weight and stress, leading to sagging.
  3. Periodic Adjustment: Occasionally adjust and ensure your cover remains taut at all times. Leveraging winter cover cables and winches, for instance, helps maintain a snug fit, thereby preventing sagging.

Solutions for Sagging Pool Covers

In response to the recurring problem of sagging pool covers, two primary solutions have proven especially effective. These include the use of water tubes and cover pumps, as well as the installation of a pool cover support system.

Use of Water Tubes and Cover Pumps

Employ water tubes to prevent your pool cover from sagging. Designed specifically for this task, water tubes—when filled and placed around the perimeter of your pool—contribute to the even distribution of weight. This method counters unbalanced forces that often result in a saggy cover.

Similar in purpose, a cover pump—an electrical device capable of pumping hundreds of gallons per hour—exemplifies a solution that addresses not just the symptoms, but the cause of your sagging pool cover. When it rains, the cover collects and holds water, leading to sagging. A cover pump, strategically placed on the pool cover, pumps out excess rainwater, thereby eliminating the primary cause of sagging.

Installation of a Pool Cover Support System

Think of a pool cover support system much like a spine. Just as a spine provides structural support to a body, a pool cover support system gives foundational support to your pool cover, preventing its sagging. Pool cover support systems come in different forms such as floats, inflated air pillows, and even specially-designed balls. Placed beneath the pool cover during installation, these devices provide the much-needed buoyancy, holding the cover up from underneath. Once utilized, you’ll find your pool cover maintains an elevated and even profile, effectively eradicating persistent sagging issues.


So there you have it. Keeping your pool cover from sagging isn’t as daunting as it may seem. With the right tools and strategies, you can easily address this common issue. Water tubes, cover pumps, and pool cover support systems are your go-to solutions. They’re designed to distribute weight evenly, get rid of excess water, and provide the necessary support to prevent sagging. Remember, a well-maintained pool cover not only preserves your pool’s integrity but also saves you time and resources in the long run. So don’t let a sagging pool cover dampen your swimming experience. Take these preventative measures and enjoy a clean, safe, and well-preserved pool all year round.

To prevent your pool cover from sagging, it’s important to regularly remove accumulated water and debris using a pool cover pump. This helps maintain the cover’s tension and prevents it from dipping and collecting more debris, which can cause further sagging, according to Swim University. Additionally, using a pool cover air pillow can provide central support, keeping the cover elevated and allowing water to drain off more efficiently.
