How a camera inspection works
A waterproof camera head on a flexible push cable is fed into the drain, usually through a cleanout. The plumber watches a live screen as it travels, and most systems record the footage and display the distance from the entry point. Many heads also carry a locator transmitter, so the plumber can find the camera's position from above ground and mark where a problem sits.
Because the lateral under an Anaheim yard is invisible and often decades old, a camera is the main way to know whether a clog came from something flushed, from roots entering a joint, or from the pipe itself having cracked, shifted or sagged.
When a camera is worth asking about
What you might see on the screen
| What it looks like | What it usually means |
|---|---|
| Hair-like strands or a mat at a joint | Root intrusion through a joint or crack |
| Water pooling with no visible blockage | A belly or sag where the pipe has settled |
| A ledge or step at a joint | An offset joint where sections have shifted |
| Rough, flaky walls in metal pipe | Corrosion and scale inside cast iron |
| Dark lines running along the pipe | Cracks, which may let roots and soil in |
| Soil or a missing section of wall | A break or collapse that usually needs repair |
How the inspection usually goes
- Clear enough to see.If the line is full of water or debris, it is usually cleaned first so the camera can show the pipe walls.
- Run the camera.The head is pushed from the cleanout toward the street or toward the house, with footage recorded along the way.
- Locate problem spots.Where something notable appears, the plumber may use a locator to mark its position and depth from above.
- Review the footage.Ask to watch the key sections with the plumber and have each finding explained in plain terms.
- Get it in writing.A short written summary with distances and any recommended next step makes it easier to compare options.
Questions to ask about the footage
- At what distance from the cleanout is each problem, and roughly how deep?
- Is the issue on my side of the line or near the city main? (Check with the city on where responsibility changes.)
- Can this be maintained with cleaning, or does it need repair?
- What would happen if I waited?
- Can I have the recording?
Common questions
Can a camera inspection be done on a fully blocked line?
Not usefully. The camera needs a path and reasonably clear water to show the pipe, so a blocked line is normally opened first.
Does a camera inspection find leaks in water pipes?
No. Sewer cameras inspect drain and sewer lines. Pressurized water line leaks are found with different leak detection methods.
Is it worth inspecting the sewer before buying a house?
For older homes with clay or cast-iron laterals and large trees nearby, many buyers find it worthwhile, because the lateral is not something a general home inspection can see.
