Why the camera comes after clearing

A sewer camera is a small waterproof camera on a push rod, fed into the lateral through the cleanout. On a blocked line, it would only show a wall of roots and standing water, so most plumbers clear the line first and then inspect it.

The camera records the trip down the pipe, often with a distance counter on screen. That number lets the plumber estimate where a problem sits relative to the cleanout, and some equipment includes a locator that can mark the camera's position on the ground above.

What you may see on the footage

Root intrusion
Roots growing into the pipe, often at joints, from thin hairs to thick masses.
Offset joint
Two pipe sections that no longer line up, leaving a lip that catches debris.
Belly or sag
A low section where water pools instead of flowing out.
Crack or fracture
A break in the pipe wall, which may be a hairline or a wide split.
Scale or corrosion
Buildup or rust on the inside of cast-iron pipe that narrows it.
Collapse
A section that has lost its shape and blocks the camera.

Get these from the inspection

  • A copy of the video file or a link to it.
  • The distance from the cleanout to each problem spot.
  • The pipe material at each section, if it changes.
  • A plain explanation of what was found, in writing.
  • Any recommendation, with the reason for it.

Questions to ask while watching

  1. Is that a joint or a crack?
  2. How far from the cleanout is this, and is that under the yard, the parkway or the street?
  3. Is the pipe holding its shape here?
  4. Would you clean this on a schedule, repair it, or both?

Common questions

Can a camera find exactly where to dig?

Many sewer cameras can be located from above with a receiver, which helps mark the spot. Ask whether your plumber's equipment does this.

Do I need a camera inspection every time roots are cut?

Not always. One good inspection documents the line. Another may make sense if symptoms change or before deciding on a repair.

Why does the camera stop partway?

It may hit a collapse, a heavy root mass, a sharp turn or standing water. The plumber should explain where it stopped and why.
