A sump pump is specifically designed to remove accumulated water from below ground levels, typically from basements or crawlspaces that are prone to flooding. It operates by collecting water in a sump pit and then pumping it out to a designated drainage area, often to prevent water damage to structures and to maintain dry conditions in underground spaces.

When groundwater levels rise or when rainwater infiltrates these areas, the sump pump activates to discharge the excess water, thus safeguarding the integrity of the building and preventing mold growth due to excess moisture. This function is crucial in flood-prone areas or environments with high water tables, making the sump pump an essential component in wet basements and similar locations.

The other options pertain to functions that do not align with the specific role of a sump pump. Elevating water pressure is handled by different systems, while filtering water for potable use involves filtration systems, and distributing hot water relates to a plumbing system focused on heating and delivering water, neither of which is the primary function of a sump pump.
