How does an emergency service crew try to remove a stoppage?

• A. Balling
• B. Flushing
• C. Parachutes
• D. Hand rods

Answer: (D)

When clearing a sewer stoppage, the crew uses mechanical rodding to physically break up and push the blockage through the line. Hand rods are inserted through the access point and worked back and forth to loosen debris and restore flow. This direct, controllable method is effective for localized, stubborn blockages that water flushing alone can’t resolve. The other options aren’t standard tools for this job: flushing relies on water to push debris and isn’t as reliable for solid clogs; balling and parachutes aren’t typical techniques used to clear sewer stoppages.
