Which tool is used to physically remove obstructions in sewers and is associated with rodding?

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

Answer: (B)

Rodding clears sewer obstructions by physically breaking up and sweeping away the blockage. The tool designed for this is the porcupine, a head with many small tines that spread out and scour the inside of the pipe as it is rotated or pushed through. This makes it effective for dislodging hard blockages like grease buildup, hair, or roots that a simple push cannot clear. The other terms listed are not used for this purpose: lag screws and set screws are types of fasteners, not sewer cleaning tools, and wildebeest is an animal. So the porcupine is the correct tool for rodding obstructions.
