Tools used for sewer rodding include all but the

• A. Porcupine
• B. Root saw
• C. Square bar cork screw
• D. Lag screw

Answer: (D)

In sewer rodding, you use attachments on rods or machines that are specifically designed to break up, cut, or pull out blockages inside pipes. A porcupine head has many small cutting projections that aggressively grind through tough material like roots and mineral buildup. A root saw is used to slice through invading roots that clog the line. A square bar corkscrew acts like a long twist bit that can snag and twist out or loosen the clog. A lag screw, however, is a wood-fastening screw used for securing boards and has no role in clearing pipes; it isn’t suited for the pipe environment and could cause damage. So the tool that doesn’t belong is the lag screw.
