This is especially important in areas where the liner may be subjected to high levels of stress, such as around the pool’s corners or near the skimmer and return jets.
In addition to providing protection, the air behind the liner also helps to ensure a smooth and even installation. When the liner is installed, the air behind it allows for a small amount of movement and flexibility, which helps to prevent wrinkles and creases from forming. This is important because wrinkles and creases can create areas where water can accumulate and cause problems, such as leaks or algae growth. By having air behind the liner, installers can ensure a tight and even fit, which helps to prevent these types of issues and ensures a longer lifespan for the liner.
How does air behind a pool liner affect its lifespan?
The presence of air behind a pool liner can significantly affect its lifespan. When air is present, it helps to reduce the stress and pressure on the liner, which can cause it to deteriorate over time. By providing a cushioning effect, the air behind the liner helps to absorb shocks and pressures, reducing the risk of damage and extending the lifespan of the liner. Additionally, the air behind the liner helps to prevent the growth of bacteria and algae, which can cause the liner to become brittle and prone to cracking.
A properly installed pool liner with air behind it can last for many years, typically between 10 to 20 years, depending on the quality of the liner and the conditions in which it is used. However, if the air behind the liner is not properly maintained, the lifespan of the liner can be significantly reduced. For example, if the air behind the liner becomes trapped or stagnant, it can create an environment that fosters the growth of bacteria and algae, leading to premature deterioration of the liner. Regular maintenance, such as checking the air pressure and ensuring that the liner is properly seated, can help to extend the lifespan of the liner and prevent these types of issues.
Can air behind a pool liner cause problems?
While air behind a pool liner is generally beneficial, it can also cause problems if not properly maintained.
