The purpose of using a sump pump is primarily to remove water that has accumulated in a sump basin. This is typically found in basements or crawlspaces where water can collect due to poor drainage or flooding. The sump pump is designed to activate when the water level rises to a certain point, efficiently pumping out the excess water to prevent potential water damage, mold growth, and structural problems associated with prolonged exposure to moisture.

By effectively managing water accumulation, sump pumps play a critical role in maintaining a dry and healthy environment in residential and commercial properties, especially in areas prone to flooding or high water tables. This function is crucial for preventing damage to foundations and interiors.
