What is sewer camera inspection?
A video inspection technique that allows plumbers to view the interior of sewer and drain pipes to identify damage, blockages, and root intrusion without digging.
A plumber performing sewer camera inspection feeds a small, waterproof video camera down a drain or sewer line on a flexible cable. The camera transmits a live feed to a monitor above ground, showing the interior condition of the pipe in real time. This method reveals cracks, fractures, tree root penetration, grease buildup, sediment accumulation, collapsed sections, or other obstructions that prevent flow or cause backups.
The inspection typically starts at an accessible point like a cleanout or drain opening and follows the pipe toward the main sewer line or septic system. The plumber controls the camera head and records the footage, which can be saved for documentation or used to plan repairs. Some systems include a distance counter and pipe locator, helping identify exactly where problems occur along the line.
Sewer camera inspection matters because it pinpoints the root cause of drain problems without guesswork or unnecessary excavation. Rather than digging up a yard to find a blockage or damage, a plumber can diagnose the exact issue, its location, and severity, then recommend the right repair method, whether that is hydro jetting, patching, or replacement.
Ontario plumbers use this tool routinely for residential and commercial drain issues, from recurring clogs to slow drainage to backup investigation. If a property owner suspects sewer line trouble, a camera inspection is often the first diagnostic step that drain and sewer specialists recommend.
