What the camera shows
- Root intrusionWhere and how many joints
- Cracks and fracturesSize and location
- Offset jointsSections out of line
- BelliesStanding water, sags
- CollapseWhere the camera stops
- Material changesOld pipe vs. past repairs
The distance counter on screen tells you how far each defect is from the cleanout. A locator then marks the spot and depth on the surface, which is what a contractor needs to price a repair.
What a good inspection report includes
| # | Deliverable | Why you want it |
|---|---|---|
| D-01 | Full video file | Lets another contractor give a second opinion without re-scoping |
| D-02 | On-screen distances | Ties each finding to a spot in the yard or street |
| D-03 | Written findings by distance | A list such as “roots at 18 ft, offset at 34.5 ft, belly 52–60 ft” |
| D-04 | Locate marks and depth | Depth drives excavation cost and method |
| D-05 | Where the lateral meets the main | Shows whether the job crosses the sidewalk or street |
| D-06 | Cleanout and OPD status | Central San requires both; their absence adds cost |
How to read the findings
Defects matter by type, count and location. One root-entry joint near the house is a repair. Roots at every joint, or a long belly under the street, point to replacement. The repair-or-replace table walks through each finding.
When to get one
- Several drains are slow at once, or toilets gurgle when another fixture drains (see sewer line problems)
- Backups that keep coming back after the line is cleared
- Before buying a home built in the 1960s–80s (see buying or selling)
- Before approving any major sewer work, or to check a quote
- Before pipe bursting: Central San requires a pre-installation TV inspection for a pipe-burst repair permit
Already have a video? A contractor can review it and tell you what they would do.
Second opinions
If one contractor recommends full replacement, a second look at the same video is a reasonable step, especially before a five-figure job. Our contractor guide lists the red flags (no footage, pressure to line a collapsed pipe, no mention of a permit). For prices, see the cost guide; for method choice, see trenchless options.
Questions homeowners ask
Is a sewer camera inspection worth it?
Usually, yes. It costs a few hundred dollars (Bay Area guides cite $250–$500+) against a lateral replacement that can run $8,000–$18,000+ (Next Level Plumbing). It's the only way to see roots, cracks, offsets and bellies before deciding on a repair method.
Do plumbers give you the video?
Ask before the inspection starts. A good report includes the video file with distances on screen and notes on each defect. If a contractor won't share footage, get a second inspection before agreeing to major work.
Can a camera find a blockage?
Yes. A camera shows where the line is blocked and what's causing it (roots, grease, a collapse, debris), and a locator can mark the spot on the surface. If the line is fully blocked, it may need to be cleared before the camera can pass.
How much is a sewer camera inspection?
Published ranges run $250–$500+ for a Bay Area inspection (Next Level) and $125–$500+ nationally (HomeGuide).
