What Is a Video Drain or CCTV Sewer Inspection?
A video drain inspection, also called a CCTV drain survey or sewer camera inspection, uses a waterproof camera attached to a flexible cable to explore your pipes from the inside. Instead of digging up your yard or walls, plumbers can see live footage and diagnose issues accurately.
Why Are Drain Camera Inspections Important?
This method offers precise pipe damage detection, identifying minor cracks, bellies, and root intrusion early before they become costly emergencies. Since it doesn’t involve digging or damage, this method helps save your time, reduce repair costs, and keep stress levels low.
Who Should Get a Sewer Camera Inspection and When?
Consider one if you:
- Have blocked drains
- Smell sewage or hear gurgling
- Notice slow drainage
- Buying or selling a home
- Manage older plumbing (over 25 years)
It’s also smart before renovations to avoid surprises later.
Step-by-Step Breakdown of a Drain Camera Inspection
Step 1 – Initial Assessment and Consultation
A skilled plumber begins with a quick survey of your home’s plumbing. They’ll ask about symptoms like recurring clogs and look for the best drainage access points, such as cleanouts or vents.
Step 2 – Access Point Identification and Preparation
Any dirt or buildup at the entry point is cleaned out, and it may be rinsed with water to help the camera pass through. This makes it easier for the camera to slide through the pipes and keeps the plumbing system safe during the check.
Step 3 – Equipment Setup: Pipe Inspection Camera Tools
The plumber prepares the camera system used for inspecting pipes, which usually includes:
- Waterproof, high-resolution camera head (with LEDs, pan/tilt/zoom)
- Long push-rod cable (30–200 ft)
- Monitor with recording and measuring tools
Step 4 – Inserting the Drain Camera: What Happens Inside the Pipe?
Here’s where the magic happens. The camera is gently fed through the pipe. The operator advances slowly, pausing at bends to inspect closely. As they watch the video live, they also save recordings and clear images to review later.
Step 5 – Real-Time Observation and Video Recording
As the camera travels, everything shows live blockages, cracks, misaligned joints, or corrosion. The footage is recorded for later review or sharing with you.
Step 6 – Identifying Common Drain Problems on Camera
The live video reveals:
- Pipe blockages and clogs from grease, hair, or debris
- Tree root intrusion, which can crack pipes
- Pipe cracks, corrosion, or misaligned joints
- Sagging or caved-in pipe sections, sometimes called sewer bellies, are also visible during the inspection.
Step 7 – Marking Pipe Locations Using Locator Tools
A radio transmitter on the camera helps technicians pinpoint exact positions under your yard or driveway. The location is marked above ground for future repairs.
What Happens After the Video Inspection?
Footage Analysis and Diagnostic Reporting
Technicians review the captured footage, annotate issues with distance markers (e.g., “8 m from cleanout”), and produce a clear, illustrated report.
Interpretation of Findings by a Licensed Plumber
A licensed plumber will explain each issue, what it means, how serious it is, and which fixes fit best. This is more than just “there’s a crack”; it’s a professional evaluation and advice.
Common Repair Recommendations Based on Camera Results
Depending on the severity:
- Using high-pressure water (hydro jetting) to clear out small clogs or grease buildup
- Root treatment (cutting plus chemical rooticide)
- Pipe lining via trenchless sewer line repair
- Full pipe replacement when damage is severe
This ensures you get targeted, cost-effective solutions.
