Do you have pool covers under winter covers?

When the winter cold sets in, many pool owners might think that simply covering their pool with a winter cover is enough to protect it until the warmer months return. However, there is more to the story than meets the eye. In this blog post, we will dive into the importance of pool covers under winter covers and why it is a crucial step in maintaining a clean and functional pool.

The purpose of winter covers

Before we explore the necessity of extra protection during winterizing, let’s first understand their primary purpose. Winter covers, also known as pool covers, serve several important functions. They protect the pool from debris such as fallen leaves, branches, and other outdoor elements, keep the water clean, and reduce the workload when it’s time to reopen the pool. Additionally, they help retain heat, prevent excessive water evaporation, and minimize the need for chemical adjustments.

However, winter covers alone may not provide complete protection for your pool during the colder months.

The hidden dangers

Although winter covers provide valuable protection against debris and heat loss, they may not be enough to protect your pool from potential damage caused by frost. In areas where winter temperatures drop significantly, the water in your pool can freeze, leading to a range of problems.

One of the most common issues is ice expansion. When water freezes, it expands, and if your pool is not adequately protected, the expanding ice can exert enormous pressure on the pool walls and bottom. This pressure can result in cracks, leaks, or even structural damage, compromising your pool’s integrity.

Furthermore, the freeze-thaw cycle can wreak havoc on pool equipment such as pumps, filters, and pipes. Water trapped inside these components can freeze, causing them to crack and fail. Repairing or replacing damaged equipment can be costly and may delay reopening your pool, when the weather warms up.

The importance of extra layers

To ensure complete protection during the winter months, it is recommended to add extra layers under the winter cover. An effective method is to use an air pillow or pool pillow. These inflatable cushions placed under the winter cover help relieve pressure from the expanding ice. By creating a cavity in the middle of the pool, they prevent the ice from pressing against the pool walls and bottom, significantly reducing the risk of damage.

Additionally, adding a layer of insulation, such as a thermal pool blanket, can provide further protection against frost. These blankets are designed to trap heat and prevent significant temperature fluctuations, reducing the likelihood of ice formation. They act as an extra barrier and protect your pool from harsh winter conditions.

Issues with routine maintenance

Besides adding extra layers of protection, it is crucial to perform routine maintenance throughout the winter. Regularly check the condition of your winter cover to ensure it remains secure and free from tears or holes. Any breaches in the cover can allow debris to enter the pool, defeating the purpose of using a cover in the first place.

Also, keep an eye on the water level. Heavy rainfall or melting snow can cause the water level to rise, potentially lowering your winter cover and making it less effective. Using a cover pump can help remove excess water and maintain the cover’s integrity.

Conclusion

While winter covers play an important role in maintaining your pool’s cleanliness and temperature during the colder months, they may not provide sufficient protection against frost. To protect your investment and avoid costly repairs, it is important to go beyond basic protection and add extra layers such as air pillows and thermal blankets. By taking these precautions and performing regular maintenance, you can ensure that your pool emerges from winter unscathed, ready for another season of enjoyment. Remember, a little extra effort during winter can make a big difference in preserving your pool’s lifespan and functionality.
