Televising and Lamping are primarily used for which type of testing?

• A. Alignment testing
• B. Infiltration testing
• C. Exfiltration testing
• D. Air pressure testing

Answer: (A)

Televising and lamping are visual inspection methods inside the sewer line. They’re used to confirm the pipe’s path and geometry—checking alignment, grade, joints, and any misalignments like offsets, sags, or bends. This interior view helps ensure the line follows the intended route and is in good alignment before proceeding with further work. Infiltration and exfiltration testing focus on water leakage into or out of the pipe, often with water or smoke tests, while air pressure testing checks how well the pipe holds pressure. Those methods don’t provide the direct interior view needed to assess alignment, which is what televising and lamping supply.
