A sewer camera is a waterproof lens with lights on the end of a stiff push cable. The operator feeds it into the line through a cleanout, a roof vent or, if there is no other way, a pulled toilet, and watches a live picture while a counter records how far the camera has travelled.
Most camera heads also carry a small radio transmitter called a sonde. With a handheld locator, the operator can stand in the yard and find the camera's position and approximate depth, then mark the ground over each defect. That is what turns a video into a dig plan.
How a typical inspection runs
- Restore flow if needed.A camera cannot see through standing sewage, so a blocked line is usually cleared first.
- Push from the best access.The camera goes in at the cleanout and runs toward the street, recording distance from that starting point.
- Stop at each defect.At roots, cracks, offsets or standing water, the operator pauses, notes the footage counter and may pan the head for a better view.
- Locate from above.The locator marks the camera's position and depth on the ground at key points.
- Reach the connection.The run ends where the lateral meets the public main, which shows the full length you may be responsible for.
- Review and copy.You get the recording or stills plus a written summary of defects by distance.
Terms you will hear on the footage
- Offset joint
- Two pipe sections that no longer line up, leaving a lip that catches waste.
- Belly or sag
- A low section where water stands instead of draining.
- Root intrusion
- Fine or matted roots growing through a joint or crack.
- Scale or tuberculation
- Rough rust buildup inside cast iron that narrows the pipe.
- Hairline or longitudinal crack
- A split along or around the pipe wall, sometimes with soil visible behind it.
- Transition
- A spot where one pipe material joins another, often from an earlier repair.
What a useful inspection report includes
- A video file or link you can keep, not only a live viewing
- The starting access point and total length inspected
- Each defect listed with its distance from the starting point
- Approximate depth at the defects that may need digging
- The pipe material for each section, including any earlier repairs
- Whether the camera reached the city connection, and if not, why
Reading the result
- IfThe line is clean, round and drains with no standing waterThenThe backup was probably a one-time clog. Note the date and keep the video.
- IfLight roots at one or two jointsThenCleaning may be enough for now; ask about a spot repair of those joints.
- IfHeavy roots or cracks at many joints along the runThenAsk about lining or replacing the whole lateral.
- IfStanding water over a long sectionThenThat is a belly, and it usually needs that section dug up and re-graded.
Common questions
Can a camera inspection damage my pipe?
A camera is pushed gently and is unlikely to cause damage. In a badly collapsed line it may simply be unable to pass the break.
Why couldn't the camera reach the street?
Standing water, a collapse, a heavy root mass or a tight bend can stop it. The report should say where and why the run ended.
Is a camera inspection the same as a hydrostatic test?
No. A camera shows the pipe's condition. A test that fills the line with water checks for leaks and is used in different situations, such as slab leak investigations.
