A sewer camera inspection sends a waterproof video camera through your drain or sewer line so a technician can see cracks, clogs, root intrusion, and pipe damage on a monitor in real time. The main advantage is that it pinpoints the exact problem and its location without digging up your yard or floors first. That precision saves time and keeps repair costs targeted instead of guesswork-driven.
TL;DR:
- A camera inspects drain and sewer interiors, not pressurized supply pipes or unseen soil problems; if blocked, technicians should try another access point.
- Request recorded video, distance readings, a written defect summary, and transmitter measurements of defect depth and position; PACP coding supports consistent review.
- Repeated backups across fixtures, sewage odors, and older homes before sale warrant inspection, especially when clay or cast iron pipes remain.
- Ask whether precleaning is included, since grease or debris can obscure footage; combining cleaning and inspection in one visit may avoid a separate appointment.

What happens during a sewer camera inspection
A sewer camera inspection uses a flexible push cable with a waterproof camera head on one end, fed through the pipe while a technician watches the feed on a monitor. Simpler push-rod cameras work well for shorter residential lines, while crawler or pan-and-tilt systems can rotate and angle the lens to examine joints and lateral connections more closely. Many units now record in HD and include a sonde, a small transmitter built into the camera head that helps locate the exact spot in the pipe from the surface.
The full setup typically includes:
- A camera head rated for underwater use, often with LED lighting built in
- A push cable or reel that feeds the camera through the line
- A monitor or recorder that displays and saves footage
- A sonde or transmitter paired with a handheld locator
Technicians usually access the line through an existing cleanout, a drain opening, or a manhole on larger properties. If the pipe is full of grease, scale, or debris, a quick cleaning or hydro-jetting pass often happens first so the camera has a clear view.
What a camera inspection reveals, and where it falls short
A camera run shows exactly what’s happening inside a pipe, which is why it has become the standard way to diagnose drain and sewer problems before any digging starts. Common findings include:
- Blockages: grease buildup, wipes, hair, or foreign objects that narrow or fully block the line
- Tree root intrusion: roots growing through joints or cracks, often visible as hairlike or rope-like masses pulling in water
- Cracks and fractures: splits in the pipe wall that let soil or groundwater in
- Joint displacement and offsets: sections that have shifted out of alignment
- Pipe bellies: low spots where the pipe has sagged, causing water and debris to pool
- Collapsed sections: areas where the pipe has caved in, usually requiring excavation to repair
Technicians also watch for early warning signs such as flattened pipe walls, standing water with no slope, or hairline fractures that tend to worsen over time. Pairing a camera inspection with hydro-jetting or snaking in the same visit lets a technician clear debris and confirm the fix on camera rather than scheduling two separate appointments.
A sewer camera is a diagnostic tool, not a universal one. It inspects the interior of drain and sewer lines, not pressurized water supply pipes, and it can’t detect problems outside the pipe itself, such as soil erosion that hasn’t yet caused a visible defect. CCTV drain cameras) are widely used precisely because they let technicians see and then target a fix without exploratory digging.
How a sewer camera inspection is done, start to finish
A typical inspection follows a consistent sequence, whether it’s a routine check or a response to a backup.
- Locate the access point. The technician finds the cleanout, drain opening, or manhole closest to the suspected problem area.
- Clear the line if needed. Heavy grease or debris gets cleared first so the camera can move freely and capture a clear picture.
- Feed the camera through the pipe. The technician advances the cable slowly, pausing at defects to record footage and note the distance traveled.
- Locate the fault from the surface. A sonde built into the camera head sends a signal to a handheld locator, giving the technician a depth and horizontal position for anything found.
- Deliver the findings. You receive recorded video, distance-meter readings tied to each defect, and a written summary. Some contractors provide a PACP-coded report that categorizes each defect using a standardized system.
If a blockage stops the camera from traveling the full length in one direction, professional practice calls for attempting the run from the opposite access point, such as a manhole or second cleanout, rather than forcing the equipment through.
Pro Tip: Ask your technician to walk you through the footage on-site rather than waiting for a written report. Seeing the defect in real time makes it much easier to understand what repair option actually makes sense.
How much a sewer camera inspection costs
Pricing depends mainly on how accessible the cleanout is, how long the line runs, whether the pipe needs cleaning first, and whether a locator and sonde are needed to pinpoint a defect. A short, accessible residential line with a readily available cleanout costs less to inspect than a long commercial run that needs cleaning and precise locating before the camera can even get a clear view.
- Accessibility matters most: an exposed cleanout is quicker to work with than one buried under landscaping or concrete
- Line length and condition affect how long the camera run takes and whether a crawler system is needed
- Pre-cleaning adds time and often gets bundled with the inspection itself
- Locating equipment adds value when you need an exact depth and position for a planned repair
The real value shows up when the inspection replaces blind guesswork. Instead of paying for exploratory digging across an entire yard, a camera run identifies the exact section that needs attention, which keeps repair costs targeted. Recorded footage and a written report also serve as documentation if you’re filing an insurance claim or applying for a municipal subsidy. The City of Toronto’s Basement Flooding Protection Subsidy Program requires video evidence of a structural issue before approving rebates for flood-prevention devices, which is a direct example of why keeping your inspection footage matters.
When you should schedule a sewer camera inspection
Some situations call for an inspection right away, while others fit into routine maintenance.
- Repeated backups or slow drains across multiple fixtures usually point to a problem in the main line rather than one clogged sink
- Sewage odors inside or near the house often mean a crack or break is letting gas escape
- New landscaping or recently planted trees near the sewer line are worth checking, since roots are a leading cause of slow intrusion
- Before buying or selling a home, request a camera inspection or ask the seller for a recent report, especially on older properties
- Rental properties and homes with aging clay or cast iron pipe benefit from a periodic check every few years, even without visible symptoms
Questions to ask before hiring a camera inspection contractor
A few direct questions separate a thorough inspection from a quick look that tells you little.
- Are your operators PACP certified, or do they follow an equivalent standard? PACP certification means the technician follows a recognized system for identifying and coding defects.
- Will I receive recorded video with distance-meter readings? Footage tied to exact distances lets you or a future contractor find the defect again without re-running the camera.
- Do you use a locating transmitter to mark the defect’s position? This turns a video into an actionable repair plan rather than just a visual record.
- How is pricing structured? Ask whether it’s a flat inspection fee or billed by distance or time, and who’s liable if equipment gets stuck in the line.
- Is cleaning or hydro-jetting included, or priced separately? Bundling a quick cleaning pass with the inspection often costs less than scheduling it as a second visit.
Standards that separate a thorough inspection from a quick look
Industry standards exist specifically so that a camera inspection produces a deliverable anyone, a future contractor, a municipality, an insurer, can actually use. NASSCO’s PACP program sets the coding and certification standard most North American contractors reference, and its CCTV specification guidance calls for centering the camera in the pipe, metering distance continuously, keeping travel speed slow enough for accurate review, and delivering footage electronically. Provincial specifications such as OPSS 409 apply similar requirements to municipal contract work, including operator certification and meter-reading tolerances.
| What to expect | Why it matters |
|---|---|
| PACP-certified operator | Consistent, auditable defect coding |
| Centered camera, metered footage | Accurate distance readings for repair planning |
| Electronic video and report delivery | Shareable documentation for insurers or future contractors |
| Locating transmitter use | Precise depth and position for spot repairs |
Standard-compliant reports matter beyond just clarity. Municipal subsidy programs and insurance claims often require documented, properly metered video before they’ll approve funding or coverage.
What experience on the job actually teaches you
We lead with a camera, not a cleaning crew, whenever a drain problem repeats or a cause isn’t obvious, since guessing wastes a visit. Bundling the camera run with hydro-jetting in the same trip usually lowers the total cost compared to booking them separately. Before we arrive, locate your main cleanout and clear access to it.

FAQ
What problems show up most often in a sewer camera inspection?
The most common findings are blockages from grease or debris, tree root intrusion at joints, cracks, offset or displaced joints, pipe bellies, and in older lines, fully collapsed sections. A technician records each defect’s distance from the access point so repairs can target the exact spot.
How do you check a sewer line with a camera?
A technician feeds a waterproof camera attached to a flexible cable through a cleanout, drain opening, or manhole, watching the feed on a monitor as it travels through the pipe. A built-in transmitter paired with a surface locator can then pinpoint the depth and position of anything the camera finds.
How much does a plumbing camera inspection cost?
Cost depends on line length, how accessible the cleanout is, and whether the pipe needs cleaning before the camera can get a clear view. Property owners can request pricing directly, since providers like High Pressure Mechanical quote inspections individually rather than publishing a flat rate.
Can a sewer camera detect blockages?
Yes, a camera inspection clearly shows blockages from grease, wipes, hair, or foreign objects, along with how much of the pipe diameter they’re obstructing. It also distinguishes a simple clog from a structural cause like a pipe belly or root intrusion that’s trapping debris repeatedly.
