What is the primary purpose of a sump pump?

The primary purpose of a sump pump is to remove water that accumulates in a sump basin, typically found in basements or crawl spaces. These pumps are vital in preventing flooding and water damage by actively managing groundwater or excess water from heavy rainfall, snowmelt, or other sources. By pumping out the water, sump pumps help maintain a dry environment, protecting the structural integrity of the building and preventing mold growth, which can occur in damp conditions.

While options like heating water in basements, filtering drinking water, and draining wastewater from sinks refer to other plumbing systems and equipment, they do not pertain to the specific function of a sump pump. Understanding the correct role of a sump pump emphasizes the importance of proper water management in preserving buildings and ensuring safety in plumbing practices.
