The answer to 'how does sewer camera inspection work' is that a sewer camera inspection uses a specialized video camera on the end of a flexible rod or cable to visually inspect the inside of sewer pipes and drains. This allows plumbers to identify issues like clogs, cracks, root intrusion, and other problems that may be causing sewer backups or slow drainage.
The plumber will insert the camera into the sewer line through a clean-out or access point, then guide it through the pipes while monitoring the video feed. This allows them to pinpoint the exact location and nature of any issues, which helps determine the best way to address the problem.
