What is one function of a sump pump?

A sump pump's primary function is to remove water from basements or other low-lying areas in a structure. It is typically installed in a sump pit located at the lowest point of a basement or crawl space, where it collects excess water that can accumulate due to rain, flooding, or groundwater seepage. When the water level in the pit rises to a certain point, the sump pump activates and pumps the water away from the foundation of the building, thereby preventing flooding and water damage. This function is crucial for maintaining a dry environment and protecting the integrity of the home.

Other functions listed do not pertain to the typical role of a sump pump. For instance, while water pressure can be a critical factor in plumbing systems, a sump pump is not designed to increase it. Similarly, maintaining humidity levels and providing heating are functions associated with different systems, such as HVAC units or humidifiers, rather than sump pumps.
