What is a sewer camera inspection?
A sewer camera inspection is a video survey of the inside of your drain line. A small waterproof camera on a flexible cable is pushed through the pipe while a monitor records what it sees, so cracks, roots and sags can be found without excavation.
The camera head carries its own LED lights and usually a self-leveling lens, so the picture stays upright as the cable twists through bends. A counter on the reel tracks how many feet of cable are in the pipe. When the camera stops at a problem, that number tells the technician exactly how far from the access point it sits.
For a Rancho Palos Verdes homeowner, the inspection answers the question that matters most: is the problem on the private side or the public side? The City makes owners responsible for the lateral all the way to the main, so knowing where a defect lies, and how long the damaged run is, shapes the entire repair. It is also the step most contractors take before quoting anything beyond a simple clog.
How does a sewer camera inspection work?
The inspection follows a predictable sequence, and each step produces information you can use later.
Access the line
The technician opens the cleanout, the capped riser near the foundation or in the yard. A two-way cleanout lets the camera travel both toward the house and toward the street. With no cleanout, the camera can go in through a toilet flange after the toilet is pulled, or through a roof vent on a single-story home.
Push and record
The cable is fed slowly so the lens can capture each joint. The technician pauses at transitions, such as a change from cast iron to clay, and at anything that interrupts the round shape of the pipe. Most systems record directly to a USB drive or a tablet, with the footage count overlaid on the image.
Locate from the surface
Many camera heads hold a small transmitter called a sonde. A handheld locator above ground picks up its signal, so the technician can stand directly over the defect, paint a mark on the lawn or driveway, and read an approximate depth. That mark is where a spot repair or an access pit would go.
Review the footage with you
A good inspection ends with a walk-through of the video: what each section is made of, where the problems are, and which ones need attention now versus later.
Pro tipAsk for the video file and a written log listing each defect by footage. A screenshot of a root mat with "42 ft" on screen is far more useful to a second contractor than a verbal description.
What are the warning signs that call for a camera inspection?
A camera inspection is worth scheduling whenever the symptoms point past a single fixture. These eight are the most common reasons people book one:
- Repeat clogs in the same drain within weeks of being snaked.
- More than one fixture draining slowly, especially on the lowest floor.
- Gurgling from a toilet or tub when another fixture drains.
- Water rising in the shower when the washing machine empties.
- A sewer odor outdoors near the cleanout or along the path of the pipe.
- A wet spot or unusually green strip of lawn that never dries out.
- Cracks in a slab, a driveway or a retaining wall above the line.
- A home purchase, a remodel or an addition that adds fixtures to an old lateral.
The last one is not a symptom at all. The City of Rancho Palos Verdes suggests owners have the lateral inspected when a property changes hands and the line has not been checked in the previous ten years, and after two or more overflows from the same lateral within two years.
What problems does the camera usually find?
In older Peninsula homes, a handful of defects account for most of what shows up on screen.
- Root intrusion. Fine roots slip through clay pipe joints and old gaskets, then thicken into a mat. On video they look like a curtain of hair hanging across the pipe.
- Cracks and fractures. Longitudinal cracks run along the pipe; circumferential ones go around it. Both let water out and soil in.
- Offset joints. One pipe section sits higher or lower than the next, creating a ledge that catches paper and solids.
- Bellies. A sag holds standing water; the camera lens dips under it, which is how technicians spot one.
- Corrosion and scale. Cast iron loses its smooth interior and develops a rough crust, while the bottom of the pipe thins.
- Deformed pipe. Bituminous fiber pipe flattens into an oval and blisters inside.
Hillside settlement and slow ground movement make offsets and bellies more common on the Peninsula than on flat ground. A camera pass is the only way to tell whether a backup came from one of these or from a simple grease clog.
What can you safely check before calling?
A few no-tools checks narrow the problem and make the call more productive.
- Run water in each fixture and note which ones slow down or gurgle. One fixture suggests a branch clog; several suggests the main line.
- Find your cleanout. It is usually a 3- or 4-inch capped pipe near the foundation, often on the side of the house facing the street.
- Look at the cleanout cap without opening it. Water seeping around it, or a cap already pushed loose, means the line is backed up.
- Walk the likely path of the pipe and look for soft ground, odor or an unusually green strip.
- Gather any past inspection reports or receipts for earlier sewer work.
WarningDo not open a cleanout cap on a backed-up line. The pressure behind it can send sewage out into the yard. Leave that to the technician.
What happens during the pro visit, step by step?
- Questions first. The technician asks which drains are affected, when it started, and whether there has been earlier work on the line.
- Clearing if needed. A camera cannot see through standing sewage, so a fully blocked line is opened with a cable machine or jetter first.
- The camera run. The camera travels from the cleanout to the connection at the street main, with recording running.
- Locating. Defects are pinpointed from the surface and marked, with depth noted.
- Explaining the footage. You see the problem on screen and hear which repair methods fit it.
- A written scope. Any repair proposal should describe the method, the length of pipe involved, the access needed and whether a City permit applies.
For a typical single-family lateral with good access, the inspection itself is usually completed in about an hour; clearing a blockage first adds time.
What affects the cost of a sewer camera inspection?
Prices vary by company and by the condition of the line. These are the factors that change the scope.
| Factor | How it changes the job |
|---|---|
| Access | A clean, two-way cleanout is fastest. Pulling a toilet or working from the roof takes longer. |
| Blockage | A line that must be cleared before filming adds a cleaning step. |
| Line length | Long laterals on deep hillside lots need more cable and more time. |
| Locating and marking | Pinpointing several defects at the surface takes extra time. |
| Report format | A written defect log and video file may be priced separately from a verbal review. |
| Timing | After-hours or same-day emergency visits are usually priced higher. |
When is it an emergency?
Skip the scheduled inspection and call right away if sewage is coming up through a floor drain, shower or tub, or if the yard cleanout is overflowing. Stop using water in the house, keep people and pets away from the affected area, and do not flush toilets. The first job is to open the line and stop the backup; the camera goes in once the pipe is flowing, to find out why it happened. If the overflow is coming from a manhole in the street rather than your property, that is a public main and goes to LA County Public Works.
Sewer camera inspection FAQs
Can a camera inspection show which side of the property line the problem is on?
Yes. The footage counter shows the distance from the cleanout, and the locator marks the spot on the ground. Comparing that with your property line tells you whether the defect sits under your yard or under the street, though in Rancho Palos Verdes the owner is responsible for both.
Do I need a permit for a sewer camera inspection in Rancho Palos Verdes?
No permit is normally needed to inspect a line. A permit from the City's Building & Safety Division comes into play if the inspection leads to replacing or relocating pipe.
Should I inspect the sewer before buying a home?
It is one of the most useful pre-purchase checks on the Peninsula, where many laterals are decades old. Ask the seller's permission for access to the cleanout and get the recording for your records.
Can the camera see through a clog?
No. Standing sewage and debris block the view, so a fully blocked line is cleared first. Partial clogs can often be filmed as they are.
Will the inspection damage my pipes?
The camera head is designed to travel through drain lines without harming them. The bigger risk is pushing through a collapsed section, which an experienced technician stops short of.
How often should a sewer line be inspected?
There is no fixed schedule. Inspect after repeat clogs, before buying or remodeling, and periodically if you know roots have been cut from the line before.
Which related services might come next?
The video usually points to the next step. Grease and scale on sound pipe call for hydro jetting, while a root mat at a single joint leads to sewer root removal and possibly a sealed joint. Cracked but round pipe is a candidate for sewer pipe lining, and a localized break near the street is usually handled as a sewer lateral repair. For the bigger picture on how these repairs fit together, see the Rancho Palos Verdes sewer line repair overview.
Homes in older sections of the city, such as Miraleste, and those near the land-movement zone, such as Seaview, tend to benefit most from a recorded baseline.
