1/3 HP Heavy-Duty Cast Iron Sump Pump with Piggyback Tethered Switch

The K2 Pumps 1/3 HP Cast Iron Sump and Effluent Pump with Piggyback Tether Float, 115-Volt (Model SPI03309TPK) helps keep basements and crawl spaces dry when groundwater reaches the sump basin. At a 10-foot lift it moves 3,120 GPH, and its no-lift max is 4,080 GPH. The tether float cycles the pump automatically and fits basins 14 inches wide and 18 inches deep. Heavy cast iron construction supports rugged sump and light effluent use. The non-clog vortex impeller passes up to 1/2-inch solids, while thermal protection helps protect the motor. A 1-1/2-inch discharge, included 1-1/4-inch adapter, and 10-foot cord ease replacement. Before buying, compare basin size, switch clearance, voltage, discharge size, and flow at the actual lift; horsepower alone does not confirm a match. The pump is CSA listed. Actual flow changes with lift and pipe resistance, so use the published curve. A check valve and a clear discharge path help the system operate as intended.
