What tool is typically used to clear clogs by pushing through or pulling out blockages in pipes?

The tool that is typically used to clear clogs in pipes by either pushing through or pulling out blockages is known as a plumber's snake. This tool is specifically designed to navigate the curves and bends of plumbing systems and can reach deep into pipes to dislodge stubborn clogs that are beyond the reach of standard plungers or other simple tools. Its flexible design allows it to adapt to the interior shape of the pipe, effectively breaking up or retrieving blockages, such as hair, grease, or foreign objects.

The other options serve different functions that do not align with the purpose of removing clogs. A drainage slope refers to the angle or gradient of a drainage system, essential for directing water flow but not a tool for clearing blockages. A pipe cutter is used to cut lengths of pipe cleanly and accurately but does not address blockages. A sump pump is designed to remove accumulated water from areas like basements or crawl spaces, helping to prevent flooding rather than clearing clogs in drainage pipes. Each of these tools plays an important role in plumbing, but only the plumber's snake specifically addresses the issue of clearing clogs within pipes.
