1. Visual inspection: Exposed piping can reveal improperly sloped piping, some improper venting issues and improper use of fittings. Older rotting cast iron pipe will start to leak through the joints. Backwards fitting and incorrect fitting combinations can be easily spotted by the trained eye.
  2. Video camera inspection: Video camera inspection can be used to determine the condition of the interior of the pipe and also the condition of piping underground or under the slab of a building. The camera can pin point the location of a breakage or blockage. A locator beacon called a "sonde" which is in the camera head tells us where the problem is located and at what depth. Using our frequency locator we can trace the camera head and the path of the piping.
  3. Floating Transmitter: The floating transmitter is like a fishing bobber but gives off a signal, we can flush the transmitter down the drain and trace the transmitters path through the pipe and where it stops. In ideal conditions, we can retrieve the transmitter by tying fishing wire to the floating transmitter.
  4. Line Energizer: We can induce a frequency into the sewer snake and trace the path of the piping and also the end of the sewer snake.
  5. Fish taping the line with markers: By inserting a metal tape into the sewer we can push the metal tape until it stops. By marking on the tape where the problem spot is located, we can pull the tape back and then lay the tape across the ground to approximate the location of the problem.
