Sewer Line Camera

A good plumber with the aid of a video camera can literally determine the condition inside the underground sewer pipe. 

The video camera will show you places in the pipe that are cracked, broken, or clogged. They can also be used to ensure that any items that were clogging your pipes have been removed. 

The video camera consists of a flexible rod with a specially designed, high-resolution video camera on its tip. The video cameras for residential use are smaller, but are similar to the cameras used by cities to inspect sewer lines. The tip also has a strong LED light. Together these are inserted into the pipe for inspection. As the rod is pushed through the pipe, the waterproof camera records its progress and findings. Video images are transmitted to the camera operator and can be saved onto a videotape for a permanent record.
