Your sewer line is one of the most expensive parts of your home to repair and the only one you never see. It runs underground from the house to the city main, often under the driveway, the garden or a patio, and it fails slowly and silently until the day it doesn’t.
A sewer camera inspection lets you see it. For many La Jolla homes, doing that once a year is one of the cheapest forms of insurance there is. Here’s why, what the camera finds, and who should do it yearly rather than every few years.
What a sewer camera inspection is
A waterproof camera on the end of a flexible push rod goes into the line through a cleanout, a capped access pipe usually near the foundation. As it travels towards the street, it records high-definition video of the inside of the pipe. A built-in counter shows the distance from the cleanout, so every defect has an exact location.
A sonde, a small radio transmitter in the camera head, lets the technician find the camera’s position and depth from the surface. That means a repair, if one is needed, digs in exactly the right place.
The footage is recorded, and you keep it.
Why La Jolla sewer lines are under extra stress
The pipes are old
A large share of La Jolla’s homes were built between the 1920s and the 1970s, with clay or cast-iron sewer laterals. Those materials can last a long time, but 50 to 100 years in the ground takes its toll. Clay joints crack and separate. Cast iron scales from the inside and corrodes along the bottom of the pipe.
The soil moves
Mount Soledad and parts of the hillsides sit on expansive clay that swells and shrinks with moisture and creeps on slopes. That movement offsets pipe joints and creates bellies, sections that sag and hold water.
The trees are big
Mature trees are one of the best things about La Jolla, and their roots are the most common cause of main-line blockages we see. Roots find even small gaps at pipe joints and grow into dense mats. See How Tree Roots Destroy La Jolla Sewer Lines.
The coast is right there
Salt air corrodes the parts of the drain system that are exposed, such as exterior cast-iron cleanouts, vent pipes and their caps. In Bird Rock and Windansea we regularly meet cleanout caps rusted solid. Near the beach in La Jolla Shores, a high water table means groundwater and fine sand can seep into cracked laterals.
Remodels mix materials
Many homes have had part of their sewer line replaced over the years. The joints where new PVC meets old clay or cast iron are common failure points, especially where the transition was done without the right coupling.
What an inspection finds
| Defect | What it looks like on camera | Why it matters |
|---|---|---|
| Root intrusion | Hair-like or matted roots at a joint | Recurring blockages, worsening joint damage |
| Offset joint | A visible step where one section meets the next | Catches debris, lets roots and soil in |
| Belly | Standing water in a low section | Holds waste, blocks again after cleaning |
| Cracks | Lines or fractures in the pipe wall | Can lead to collapse, lets groundwater in |
| Scale and corrosion | Rough, flaking crust, often along the bottom of cast iron | Narrows the pipe, catches grease |
| Sand and sediment | Layer along the pipe bottom | Narrows the line, common near the beach |
| Grease | Coating on the pipe walls | Builds until it blocks |
The value of the inspection is that it catches these while they’re small. A few roots at one joint can be cut and the joint sealed with a trenchless spot repair. Five years later, the same joint may have cracked the pipe around it.
Who should inspect every year
Annual inspection makes sense for:
- homes with clay or cast-iron sewer laterals, which covers most La Jolla homes built before about 1980,
- any home with a history of root intrusion or main-line backups,
- properties with large trees near the line of the sewer pipe,
- hillside lots where soil movement is a factor,
- beach-area homes with a high water table or a history of sand in the line,
- restaurants and multi-unit buildings, where grease loading is heavy and a backup affects many people.
Who can wait longer
A home with a newer PVC sewer line, no large trees nearby and no history of problems can usually go two to three years between inspections. A new home under warranty may not need one at all.
When an inspection is essential
Even if you don’t want an annual check, get the line filmed:
- before buying a home. In the City of San Diego the property owner is responsible for the sewer lateral. A failed lateral discovered after closing is your bill, and it can run to five figures. A pre-purchase inspection with a written report is $325 to $450.
- before a big landscaping or hardscape project. If the line needs repair, do it before the new patio goes over it.
- before agreeing to a large repair. If someone tells you that you need a new sewer line, ask for the footage. If they won’t show it, get a second opinion.
- after any backup. Find out why it happened.
What it costs
- Added to a cleaning visit: $150 to $225. The line is already open and cleared, so this is the cheapest way to do it.
- Standalone residential inspection: $275 to $395, from the cleanout to the city connection.
- Pre-purchase inspection with a written report: $325 to $450.
- Sonde locating to mark a defect on the surface: $95 to $150 extra.
- Commercial inspections: priced by line length and access points, from $395.
Compare that with the cost of a sewer repair under a driveway, and an annual inspection pays for itself the first time it catches something early. See our sewer camera inspection page for details, including commercial inspections.
What happens during an inspection
- We find and open the cleanout. In coastal homes this sometimes means freeing a corroded cap first.
- We check whether the line is clear. A camera can’t see through standing wastewater. If the line is backed up, it gets cleared first.
- We run the camera to the city connection, noting the distance and nature of every defect.
- We locate any problems from the surface with the sonde, if repair might be needed.
- We review the footage with you and explain what we saw in plain language.
- You keep the recording. If repair is needed, you get a written quote based on the footage, and you’re free to take that footage to anyone else for a second opinion.
Frequently asked questions
How long does a sewer camera inspection take?
A typical residential inspection takes 45 minutes to an hour and a half, including going through the footage with you.
Can a camera inspection damage my pipe?
No. The camera is pushed gently through the line. It doesn’t use pressure or cutting.
What if my house doesn’t have a cleanout?
We can often go in through a toilet flange or roof vent. If you don’t have an exterior cleanout, it’s worth adding one. It makes every future inspection and cleaning quicker and cheaper.
