What is required if parts of the liner are exposed to direct sunlight?

If parts of the liner are exposed to direct sunlight, it is crucial to cover them to protect against UV damage. Prolonged exposure to sunlight can degrade the materials used in liners, leading to issues such as loss of structural integrity or degradation of the material itself. Coverage shields the liner from harmful UV rays, ensuring that its lifespan is extended and that it continues to perform effectively in its function, such as in a septic system where maintaining the integrity of the liner is essential for preventing leaks and ensuring proper operation.

While painting or reinforcing the liner could provide some level of protection, the primary and most effective method is to cover it. Removing the exposed sections entirely may not be practical or beneficial, as it would compromise the overall system. Thus, covering the exposed areas serves as a proactive and necessary step in maintaining the system's health and effectiveness.
