The cleanout cap comes loose with a quarter-turn. A push cable feeds off its reel, the camera head disappears into the pipe, and a picture flickers onto a monitor balanced on the tailgate. You are watching the inside of a sewer line nobody has seen since the day it was buried.
The plan was a wider driveway, or a shop pad, or just an answer to a drain that keeps backing up. Nobody can say exactly where the old lateral runs, and nobody wants to find out with a machine. That is what a sewer camera inspection is for. It answers where the problem is, what it is, and how much pipe is actually in play, before anyone breaks ground.
What a Sewer Camera Inspection Shows Inside the Line
The tool is simple to describe. A camera head rides a push cable into the line through a cleanout or other access point, and the operator watches the picture on a monitor. Many heads carry a sonde, a small transmitter that lets the line be traced from the surface with a receiver. Put simply: eyes inside the pipe, and a way to mark what they find in the yard above it.
Able's
utility installation and repair page describes its sewer camera service in plain terms: video inspection of existing sewer lines to diagnose blockages, root intrusion, pipe collapse, and offset joints before excavation, so the dig targets the exact location of the issue. Here is what those words look like on screen.
Buildup, grease, and scale
Buildup reads as a narrowing. Grease shows up as a thick, clinging coat, common on kitchen and food-service laterals. Scale, the mineral crust that hard water leaves behind, can narrow a line over the years. Remodeled properties add their own category: drywall mud, mortar, and renovation leftovers that found their way into a line left open during work. The key distinction is what sits behind the buildup. A blockage with sound pipe behind it is a different job than a blockage inside a failing pipe.
Root intrusion
Roots get in through joints and hairline cracks, chasing water. It is classic in older clay and concrete tile laterals, especially where lines run near mature trees or ditch and irrigation corridors. On screen it usually reads clearly: fibrous masses showing up at regular intervals, which typically maps to the joint spacing. One caution worth carrying: roots are a symptom. The joints they came through are the condition to plan around. Clear the roots and ignore the entry points, and you will meet them again.
Cracks, collapses, and bellies
Three terms, three problems. A fracture is a crack in the pipe wall. A collapse is a section that has given up entirely; the run ends and the picture goes dark or fills with mud. A belly is a low spot where the pipe has sagged and now holds standing water, which reads as pooling in an otherwise clear line. A belly usually means the bedding or soil support under the pipe failed. In other words, the problem is under the pipe, not just in it.
Offset joints and separated fittings
An offset joint is two pipe sections that have shifted out of line, often from soil movement, settling fill, or a past project that patched a cut line. This is where the camera earns its keep ahead of the backhoe. One known offset at one known point can mean a small, targeted dig instead of opening the whole line. Multiple offsets along a run change the conversation entirely.
Pipe material and route
A lateral may be clay tile, cast iron, concrete, ABS, or PVC, and on long-held properties it may be something older or a patchwork of several. Transition points between materials are frequent failure spots, especially where an older lateral was spliced into newer pipe. The run also documents the route from house to tap or tank, confirms lateral connections, and locates cleanouts. On acreage properties a long lateral crossing a driveway, a ditch, or a corral is expensive to hunt for with a trencher.
