What is the primary function of a sump pump?

The primary function of a sump pump is to remove water from basements. This is particularly important in areas where groundwater levels are high or where heavy rainfall can lead to flooding. A sump pump is typically installed in a pit, or sump basin, located in the lowest part of a basement or crawl space. When water enters this pit, the sump pump activates and pumps the water out and away from the foundation of the house, preventing water accumulation that could lead to structural damage, mold growth, and other issues.

While handling wastewater and circulating hot water are important plumbing functions, they are not the primary role of a sump pump. Wastewater management is typically handled by sewage pumps or other outdoor drainage systems, and hot water circulation involves a different set of systems focused on maintaining temperature and flow of water for heating needs. Preventing pipe leaks is a maintenance concern, but it does not directly relate to the function of a sump pump, which is specifically designed to address water infiltration issues in low-lying areas of a property.
