What the camera shows you
The camera records as it travels. The plumber narrates what it finds: pipe material, joints that have slipped, roots entering, hardened grease, a low spot that holds water and any collapse. The footage gives you something to compare when you get a second opinion.
A camera inspection does not repair anything, and it cannot see through a full blockage. If the line is backed up, the plumber clears it first. See sewer line cleaning for that step.
Three times a camera look is worth it
- Before buying a home. A pre-purchase scope of a 1950s lateral reveals problems the seller may not know about. It can change the offer or the negotiation.
- After a repeat backup. If a cable has cleared the same line twice, the camera tells you whether you have a habit problem or a pipe problem.
- Before a repair or remodel. Whether you are planning sewer line repair, an addition or a new driveway, the camera maps the lateral first.
| Finding | Visible on camera | Notes |
|---|---|---|
| Root intrusion | Yes | Shows where roots enter and how heavy |
| Cracks and offsets | Yes | Joints that shifted are clear |
| Bellies (low spots) | Yes | Standing water in the pipe shows the dip |
| Pipe material | Usually | Clay, cast iron and plastic look different |
| Location of the break | With a locator | A locating tool marks it above ground |
| Leaks in supply pipes | No | Use leak detection for pressurized water lines |

Call (650) 860-1670What you get after the inspection
You get a plain-language explanation of the condition of the line, a recording of the run and the location of any problem found, marked at the surface when a locator is used. If the line is sound, you leave knowing it. If it is not, you see the repair options and prices side by side.
No repair is started from an inspection call unless you approve it. The inspection is its own service and its own price.
What decides the cost of a sewer inspection
- Access. A cleanout makes the job quick. Without one, the plumber may pull a toilet.
- Line length. A long lateral takes more time than a short one.
- Clearing first. If the line is blocked, cleaning comes before the camera.
- Locating. Marking the problem above ground uses a locator and adds time.
- Report. Video and a written summary for a purchase or insurer take more time than a quick look.
A camera inspection usually costs less than a single excavation and can save you from digging in the wrong place. The price is stated before the camera goes in.
Reading the video with the plumber
Ask the plumber to pause the recording at each finding and explain it. Root hairs look like fine white threads across the pipe. Cracks appear as dark lines or gaps. An offset joint shows a step where two pipe ends no longer line up. A belly appears as water standing in the bottom of the pipe along a stretch.
Ask how far from the cleanout each finding sits and how deep the pipe runs there. Those two numbers decide whether a repair means a small dig or a long trench.
Why scoping matters in older Mountain View streets
The City's FAQ places the lateral on the property owner, so a defect you inherit at closing is yours. Fairview's Eichler homes date to about 1954 to 1957 per the City's historic context statement, and the sewer lines under them are the same age. Those facts are why many buyers in older Mountain View neighborhoods ask for a scope before they commit.
A camera inspection is not code enforcement, but its findings are judged against the California Plumbing Code when a repair is permitted, which is why the recording matters to the inspector as well as to you.
Sewer inspection questions
How long does a sewer camera inspection take?
A straightforward lateral often takes under an hour once the plumber has access. A blocked line or a long run takes longer.
Do I get the video?
Ask for it when you book. A recording lets you compare repair quotes and share the findings with an insurer or seller.
Is a camera inspection useful when buying a house?
Yes, especially on a home built before the 1980s. It shows whether the lateral has roots, cracks or a belly that could become your repair bill.
Can the camera find a leak in my water pipes?
No. It travels through drain lines. For pressurized water leaks, see leak detection.
Is an inspection the same as a repair?
No. The inspection finds the problem. Repair is a separate decision with its own price.
