What is the primary function of a sump pump?

The primary function of a sump pump is to remove excess groundwater to prevent flooding. Sump pumps are commonly installed in basements or crawl spaces where water accumulation can occur, particularly in areas prone to heavy rainfall or high water tables. The pump collects water that seeps into the sump basin and automatically pumps it out of the building, directing it away to a suitable outlet. This process mitigates the risk of flooding, property damage, and unwanted moisture that can lead to mold growth and structural issues.

The choice regarding increasing water pressure pertains to different types of pumps, such as booster pumps, which are used specifically to enhance water flow. Heating water relates to water heaters that are designed to provide hot water for domestic use. The option concerning supplying water to irrigation systems refers to irrigation pumps, which serve a different purpose by delivering water to agricultural or garden settings. Understanding these specific functions helps clarify why the sump pump's role in flood prevention is vital in plumbing and home maintenance.
