A baffle partially encloses the float to prevent nuisance trips resulting from liquid turbulence in the sump caused by pump operation. A cover is provided over the float mechanism to prevent nuisance trips causes by overspray striking the float. In its preferred from the float assembly comprises a multi-chamberedopen bottom float portion and an inverted U-shaped stem portion. One end of the U-shaped item is connected to the float. The free end is slidably supported in a vertical standpipe formed in the bottom of the sump. The free end projects externally from the sump through the standpipe to operatively engage a switch mounted beneath the sump. The switch is operative to enable and terminate liquid fill.
