What is the primary function of a sump pump?

The primary function of a sump pump is to remove water from basements or crawl spaces. Sump pumps are installed in a sump pit, often located in the lowest part of a basement or crawl space, where they collect excess water that may enter due to various reasons, such as heavy rainfall, melting snow, or rising groundwater levels. When the water reaches a certain level, the sump pump activates and pumps the water out and away from the home, thereby helping to prevent flooding and water damage. This device is crucial in maintaining dry and safe living spaces, particularly in areas prone to water accumulation.

The other choices reference functions that are not related to the primary purpose of a sump pump. Distributing hot water throughout the home relates to a hot water heating system, while pressure testing plumbing systems involves assessing the integrity of pipes under pressure. Supplying water to irrigation systems is focused on landscape watering and does not involve the removal of water as is the case with a sump pump.
