Camera Inspection
Also known as Sewer camera, CCTV inspection
Video inspection of interior pipe conditions using a waterproof camera on a cable or crawler, transmitted to an above-ground monitor.
Camera inspection involves feeding a small waterproof video camera through a drain or sewer line to visually diagnose blockages, breaks, root intrusion, scale buildup, misaligned joints, and deterioration. The operator controls the cable reel from a portable unit at ground level, watching a real-time feed on a monitor while advancing the camera upstream or downstream through the pipe. Some units include a sonde (radio transmitter) that allows locating the camera's depth and position above ground.
In the field, this is the fastest way to pinpoint problems without digging. Before running camera, clear gross blockages with a snake or jetting — you don't want the head hanging up on debris five feet in. The footage can be recorded and saved, making it evidence for warranty claims, insurance disputes, or contractor estimates. High-quality units show you exactly where and what the damage is, cutting guesswork out of the sales pitch and repair scope.
Camera inspection is nearly mandatory before committing to a dig, burst, or reline job. It's also the only way to verify a line is actually clear after you've snaked it, and to identify which lateral needs attention when a customer has multiple problem drains. Cost typically runs $250 to $500 per inspection depending on line length and accessibility.
