The answer to 'what is a sump pump' is a device that helps remove excess water from a home's basement or crawl space. Sump pumps are typically installed in a sump pit, which is a small hole dug in the lowest part of a home's foundation. When groundwater or heavy rain causes the sump pit to fill with water, the sump pump automatically activates and pumps the water out and away from the home, preventing flooding and water damage.
Sump pumps are an important part of a home's drainage system and can help protect the home's foundation, walls, and floors from water damage. They are commonly used in areas with high water tables or in homes located in flood-prone areas. Proper maintenance and regular testing of the sump pump is important to ensure it is working correctly and ready to handle heavy rain or flooding.
