What hazard can damage a TV camera used in sewer inspections?

Offset joints are conditions in sewer lines where two sections of piping are misaligned. This misalignment can create stress points where physical obstructions or uneven surfaces can occur, potentially damaging sensitive equipment like a TV camera used for inspections. The camera, which is designed to traverse the sewer line and capture video and images, can be negatively impacted by obstacles that result from offset joints. These conditions can cause the camera to become stuck or damaged due to the abrupt changes in alignment, thus making it critical to be aware of such risks during sewer inspections.

While other hazards like tree roots, water pressure, and debris present challenges in sewer environments, the specific threat posed by offset joints directly relates to the structural integrity and navigational capabilities of the camera system used in these inspections. Understanding how these varying conditions can affect inspection equipment is essential for maintaining its functionality and efficacy in assessment tasks.
