Tools used for sewer rodding include

• A. porcupine
• B. lag screw
• C. set screw
• D. wildebeest

Answer: (A)

Rodding a sewer relies on a tool that can be inserted into the pipe and interact with the blockage to loosen and remove it. A porcupine-type rodding head uses many small, bristle-like projections to scrub the interior surface and break up debris as the rod is advanced. This design is specifically intended for within-pipe contact and clearing obstructions, making it appropriate for sewer rodding. In contrast, lag screws and set screws are fasteners not meant for use inside pipes, and wildebeest is an animal with no relevance to pipe maintenance.
