What is the primary purpose of a sump pump?

The primary purpose of a sump pump is to remove accumulated water from basements or crawl spaces. This device is typically installed in a sump basin, which is a pit dug into the lower part of a basement or crawl space. When water collects in the basin, whether from groundwater seepage, rain, or other sources, the sump pump activates to pump the water out and away from the building. This prevents water damage, mold growth, and structural issues that can arise from standing water. The effective removal of excess moisture helps to maintain a dry and healthy environment within the building.

Other options, such as cooling the air, circulating air, or providing humidity, do not pertain to the primary function of a sump pump, which is specifically designed for water removal.
