Video camera inspections can get to the cause of the problem in a timely and efficient manner. If you experience repeated slow drains, sewer or drain line backups, or frequent toilet clogs, it may be a good idea to have a video inspection performed to determine the underlining problem. The cameras are built into a cord or snake that is connected to a video monitor. The operator pushes the camera snake through the pipeline, and since the camera head is ringed with bright lights, the pipeline can clearly expose obstructions, cracks, and structural damage in the pipe. Video inspections are also strongly encouraged to prospective homeowners before buying a new home. After all, the cost of sewer replacement can be many thousands of dollars.
