What is the primary purpose of a sump pump?

The primary purpose of a sump pump is to remove excess water from a basement or crawl space. Sump pumps are typically installed in a sump pit, where they automatically activate when water levels rise to a certain point. This prevents flooding and water damage in areas where water naturally accumulates, especially during heavy rains or melting snow. By efficiently directing excess water out of the basement or crawl space and away from the foundation of the home, sump pumps protect the structural integrity of the building and help maintain a dry environment, which is critical for preventing mold growth and other moisture-related issues.
