SEWER INSPECTION

A sewer camera can document a visible crack and its location, but an uncalibrated image usually cannot provide a reliable crack-width measurement. Here is why.

A sewer camera can document standing water and flow behavior, but ordinary scope footage does not directly measure pipe slope or grade. Learn what the video can support.

Push footage and pullback footage show the same sewer line from different motion and lens conditions. Using both can clarify defects, water, access limits, and location.

A sewer camera skid can center the lens and improve the view of joints, walls, and flow channels, but it cannot remove every blind spot or turn footage into a dimensional survey.

In a sewer scope report, serviceable should mean that the inspected section was functioning and did not show a repair-level condition at the time of inspection. It is not a lifetime guarantee. A buyer should confirm which pipe was visible, what conditions were present, and which sections remained outside the camera’s reach.

An observed defect is something the camera actually records, such as a visible offset, root entry, crack, deposit, or passage limit. A suspected cause is an interpretation, such as soil movement or installation error. A strong report separates those two so a DFW owner does not authorize a repair from an assumption.
