Below is a list of Sump Pumps manufacturers from New Brighton, Minnesota. Also known as dewatering pumps or basement pumps, sump pumps come in handy when there is water on a low-lying surface. Sump pumps are designed to empty accumulated water from a basement, well, or sump and pumps it outside. Used for drainage purposes, sump pumps pump the flows up onto outside ground surfaces and keep areas from flooding.
