Sewer camera inspection is the diagnostic that turns 'we think it's X' into 'it's definitely X'. The technology has been around for decades but the resolution and reliability have improved dramatically — modern push cameras have full-colour HD video, on-screen footage counter, and a sonde that emits a locator signal so we can mark the exact location of any issue on the surface above. For most Lower Mainland homeowners, a sewer camera inspection is the single most useful $200–400 they'll spend on their plumbing system.
What the camera physically is and how we use it
A residential sewer camera is a 1–1.5 inch waterproof camera head on the end of a flexible push rod, typically 100–200 feet long, with LED lighting on the head. The rod feeds out of a reel mounted on a wheeled rack, with a colour monitor that the plumber watches while pushing the camera through the line. A footage counter shows exactly how far in we are. The sonde in the camera head emits a 512 Hz signal that a surface locator can detect, so we can mark on the lawn or driveway exactly where the camera (and the issue) is below ground.
The 7 things a sewer camera shows
1. Pipe material and age
The first 10 seconds of footage tells us whether the line is clay tile (red-brown segments with mortar joints, 1940s–1970s installs), cast iron (dark grey, often heavily scaled, 1950s–1980s), Orangeburg (compressed cellulose, sometimes called 'bituminized fiber pipe', 1940s–1960s, almost always failing), modern ABS or PVC (white or off-white, smooth interior), or HDPE (black, fused joints, 2000s+).
2. Blockage location and type
The exact footage and visual identification of what's blocking the line: grease coating, paper accumulation, root mass, foreign object, mineral scale, or structural failure. The footage counter shows the location; the visual diagnosis drives the right treatment.
3. Root intrusion
Roots enter the pipe at joints and cracks. The camera shows the size of the root mass and the location of entry — critical information for deciding between hydro-jetting (cuts current roots) and pipe-bursting/lining (eliminates the entry point permanently).
4. Cracks, offsets, and partial collapses
Structural issues are visible directly. Cracks show as horizontal or longitudinal lines in the pipe wall. Offsets show as a step where one pipe section meets the next at the wrong elevation. Partial collapse shows as a deformation in the pipe interior.
5. Belly / negative grade
A 'belly' is a section of pipe that has settled below its proper grade, creating a low spot where solid waste pools instead of flowing through. Visible on camera as standing water sitting at the lowest point. Common in older Lower Mainland clay-tile lines where ground has settled over decades.
6. Lateral connections
The camera shows where branch lines tie into the mainline — kitchen, bathroom, laundry, sometimes a separate basement bath. We can confirm that each connection is properly tied in (especially relevant in older homes that have been renovated multiple times).
7. The municipal connection point
The mainline runs from your house out to the city sewer at the property line. The camera tells us the condition of the line all the way to the connection — critical information when there's a backup question about who's responsible (the homeowner owns the line up to the property line; the city owns from there).
The four scenarios where a camera pays for itself
1. Pre-purchase home inspection
When you're buying an older Lower Mainland home — anything pre-1990 — adding a sewer camera inspection to the home inspection is the single highest-value diagnostic spend a buyer can make. We've helped buyers either negotiate the price down by tens of thousands of dollars when the camera shows an end-of-life sewer line, or confirm a healthy line and proceed with confidence. The cost is a fraction of what a sewer replacement after closing would cost.
2. Recurring backups in the same line
If you've had the same drain clear twice in a year, the camera tells you whether the cause is structural (roots, collapse, belly) or behavioural (grease build-up from how the kitchen is used). The fix depends entirely on which it is — and cabling without diagnosis just buys you another six months.
3. Post-flood / insurance documentation
After a sewer backup that caused damage, the camera video is gold for the insurance claim. It shows the root cause, the location, the extent. We provide the video file and a written locator report with every camera inspection.
4. Pre-trenchless repair
Trenchless methods (pipe-bursting, CIPP lining) require the existing line to be in specific conditions. A pre-repair camera inspection confirms whether trenchless is viable and avoids the bad scenario of starting a trenchless job that has to be converted to open-cut mid-way through.
What the camera doesn't show
Honest limits, so you know what you're buying:
- Pipe material composition (we infer from visual appearance, not lab analysis)
- Exact pipe diameter (we estimate from on-screen scale — usually accurate to ±1/2 inch)
- Active leak locations on a pressurized supply line — the camera is for drain lines, not pressurized water lines
- Soil condition around the pipe — that's a different tool
What you get when we do an inspection
- Real-time monitor showing the camera footage as we run the line — homeowner is welcome to watch
- Digital video file of the complete run, delivered the same day
- Locator report — surface markings of any issues found, plus a written summary
- Direct, plain-language recommendation: what to do, what to monitor, what to ignore
- If repair is needed, a free written estimate covering options (cabling, hydro-jet, lining, bursting, open-cut) so you can make an informed call
Frequently asked
How long does an inspection take?
Most residential mainline inspections take 30–60 minutes from arrival to handing over the video. Pre-purchase inspections we can usually do same-day on request.
Do I need to dig anything up?
No. We access the line through an existing cleanout (a capped pipe stub above ground, usually outside the foundation on the sewer-line side of the house). If your home doesn't have an accessible cleanout — common in older Surrey homes — we may use a toilet pull as the access point instead.
Will my warranty/insurance cover the inspection?
Inspection itself is usually homeowner-paid. If the camera reveals an active emergency or covered failure, your insurer may reimburse — we provide the documentation either way.
