Which mechanical tool is designed to clear blockages in larger or deeper pipes?

The plumbing auger is specifically designed for clearing blockages in larger or deeper pipes. This tool features a long, flexible metal shaft with a coiled end that can navigate through curves and bends in the plumbing system, effectively breaking up or dislodging clogs that are further down the line. Its design allows it to reach greater depths and tackle more substantial blockages compared to other tools.

While a plumber's snake is also a common tool used for clearing smaller drain clogs, it typically works best in relatively shallow pipes and may struggle with more significant obstructions found in larger pipes. Fixture units refer to a measure used in plumbing design but do not pertain to a physical tool for clearing blockages. Water hammer is a phenomenon related to pressure changes in plumbing systems and not a tool used for clearing blockages.
