What is the function of a sump pump?

The function of a sump pump is to remove excess water from basements and crawl spaces. This is particularly important in areas prone to flooding or where the water table is high, as these conditions can lead to water accumulating in lower areas of a home. The sump pump typically sits in a sump pit, often located in the basement, and activates when the water level rises to a certain point. By pumping out this excess water, the sump pump helps to prevent water damage, mold growth, and structural issues in a home.

Other functions such as regulating home temperature, enhancing air circulation, or filtering air quality are not related to the primary purpose of a sump pump, which is specifically to manage water accumulation.
