What is the main function of a sump pump?

The main function of a sump pump is to remove excess water from basements. This device is particularly important in areas that are prone to flooding or where groundwater levels are high. A sump pump is typically installed in a sump pit, which is a pit dug into the lowest part of a basement or crawlspace. When water enters the pit, the sump pump activates and pumps the water out of the pit, directing it away from the foundation of the building. This helps to prevent water accumulation, which can lead to serious issues such as mold growth, structural damage, and damage to personal belongings.

In contrast, other options relate to functions that are not relevant to sump pumps. Measuring plumbing loads involves assessing the requirements of various plumbing fixtures, which is not a role of a sump pump. Clearing drainage pipes pertains to removing blockages, again unrelated to the sump pump's design. Cutting pipe materials entails using specific tools for shaping or resizing pipes, which is outside the pump's function.
