Roots
Roots indicate an opening or joint that provides moisture. Density and flow restriction help determine the next question.
Offsets
A joint offset can be minor or can catch debris, restrict the camera, leak, or reduce the effective pipe opening.
Bellies and standing water
Water depth, length, and whether the camera can traverse the section help describe the practical impact.
Scaling and deposits
Interior buildup can narrow the pipe and obscure its surface; material and structural condition affect cleaning choices.

independent sewer education FAQ
Is this an industry association?
No. SewerInspection.org is an educational website published by Spokane Rooter LLC.
Can camera footage prove pipe depth?
Not by itself. Locating equipment and site measurements may be required for reliable position or depth information.
Do all visible cracks leak?
A camera image alone may not prove leakage. The inspector should describe what is visible and avoid unsupported certainty.
