Notice the signs
Observe
Before inspection, map the access point, flow direction, pipe material if known, connected fixtures, prior clearing, line status, and the question the recording must address. Require on-screen distance and a continuous orientation.
Protect the room
Safety line
Do not force equipment through a blocked or fragile line, open an unsafe cleanout, or treat a distant reading as an excavation mark. Contaminated access and rotating equipment need controlled work space.
Material note
Local boundary
Connection and maintenance boundaries still depend on Cohasset sewer records, property information, and field locating. A town drainlayer requirement may apply if the next step modifies or repairs the service.
Service flow
Written scope
The quote should name cleaning prerequisites, access, camera size, recording format, distance reference, locator use, limitations, retrieval plan, fixture reinstatement, and whether a written interpretation is included.
Close the loop
Verification
Retain the full video rather than selected stills, with date, address, starting point, direction, narrated landmarks, and locator marks if used. Compare a repair proposal to the actual frames it cites.
