The TSW Submersible Sump Pump is an innovative alternative to the traditional submersible sump pumps. This pump features a solid state 'IntelliSwitch' automatic switch and alarm circuit that eliminates the potential hang ups seen with float switches. The alarm portion of the circuitry is built into the 'IntelliPlug' power cord plug. It has an audible alarm and a red warning light to indicate a high water condition in the sump. The 'IntelliPlug' also has a green run light to show the pump is operating.
