When a technician finds a leak in a flexible duct system, what should be checked?

When a technician encounters a leak in a flexible duct system, it is essential to check all connections including both the inner and outer layers of the duct. This comprehensive inspection is necessary because leaks can occur not only at the joints where different sections of ductwork connect but also along the seams where the inner and outer materials meet. Any gap or deterioration in these areas can lead to significant air loss, reduced system efficiency, and potential issues with air quality and pressure balance within the system.

By examining all connections, including those covered by the outer layer, the technician can identify and address potential leaks effectively. This approach ensures that no possible area of leakage is overlooked, allowing for repairs that will restore the system to optimal performance. The focus on both the inner and outer layers highlights the importance of thoroughly assessing all components of the flexible duct system, as leaks can compromise the entire duct's integrity.
