The answer to 'how does sump pump work' is that a sump pump is a submersible pump installed in the lowest part of a basement or crawl space, known as the sump pit or basin. When groundwater or stormwater collects in the sump pit, the sump pump automatically turns on and pumps the water out and away from the home's foundation, preventing water damage and flooding.
Sump pumps are typically powered by electricity, with a backup battery system in case of power outages. They are connected to a drainage pipe that leads the water to a safe location, such as a storm drain or dry well, away from the home's foundation. Sump pumps play a crucial role in protecting homes from water damage and are an essential component of a home's drainage system.
