What is CCTV drain inspection?
CCTV drain inspection is a non-invasive method that uses a small camera mounted on a flexible cable to examine the interior condition of drain and sewer pipes, identifying blockages, structural damage, and root intrusion.
CCTV (closed-circuit television) drain inspection is a diagnostic technique that threads a camera on a flexible cable into drain and sewer pipes to view their interior condition in real time. The operator guides the camera through the pipe while monitoring a live video feed on a screen, recording any damage or obstructions found along the way.
Common problems identified during a CCTV inspection include blockages from grease, debris, or mineral buildup; structural cracks or breaks in the pipe; tree root intrusion; pipe misalignment; and sagging sections. In Klang Valley properties, root intrusion from nearby trees is a frequent issue that CCTV can pinpoint before it becomes a costly problem.
The main advantage is accuracy without disruption. Rather than excavating an entire run of pipe to locate a problem, the camera shows exactly where and what the issue is. This allows plumbers to recommend targeted repairs, from chemical root removal to spot patching or full-length pipe replacement as needed. CCTV records also serve as a baseline for future reference or warranty documentation.
For drain unclogging and inspection services, CCTV is often the first diagnostic step when conventional snaking fails or when the cause of poor drainage is unclear.
