Which tool is not typically used for sewer rodding?

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

Answer: (A)

Tools for sewer rodding are chosen for navigating pipes and actually clearing or cutting blockages without harming the pipe. A lag screw is a wood fastener designed to join pieces of wood; its point and threads are meant for wood, not for clearing pipes. In a sewer line, a lag screw wouldn’t effectively remove a clog and could snag or damage the pipe if forced through bends. By contrast, a porcupine is a rotating tool with multiple blades to slice through roots, a root saw is designed to cut through intruding roots, and a square bar cork screw acts as a rigid auger to twist through tougher obstructions. So the lag screw isn’t used for sewer rodding because its design and purpose don’t fit the task of clearing a pipe.
