This pump automatically checks to see if water is present every three minutes. Once the pump turns on, it pumps until the water is within 1/4" from the floor if the screen is removed. This 1/4 HP utility pump is perfect for locations with intermittent water pumping requirements. This pump is ideal for water removal from basements, rooftops, crawl spaces and other areas that may be difficult to monitor. Running on a 115V power supply, this pump has a 1.25” MNPT discharge and includes a garden hose adaptor.
