The answer to 'types of sewer camera inspection' is that there are several main types of sewer camera inspection that plumbers use to inspect and diagnose issues with sewer lines. The most common types are:
Push Camera Inspection: This uses a small, flexible camera on the end of a long rod that is pushed through the sewer line to visually inspect the pipe. It's good for shorter runs and can identify cracks, blockages, and other issues.
Lateral Launch Camera Inspection: This uses a camera on the end of a long hose that can be launched from a main sewer line into the smaller lateral lines that connect to a home. It allows inspection of the entire sewer system.
Robotic Camera Inspection: This uses a remote-controlled camera system that can navigate through sewer lines, providing a comprehensive video inspection. It's useful for longer runs and more complex sewer systems.
