The model 247, a 1/4-horsepower sump pump by Liberty, features a one-piece cast iron body that eliminates multiple part construction and features peripheral-port suction. The quick-disconnect power cord allows simple replacement of cords, available in lengths of 10, 20 and 30 feet. It has a tight profile allowing it to operate in a minimum 10-inch diameter sump. It comes with a two-year warranty. Liberty.
