ABSTRACT:
A well point system is provided having automatic regulation of the flow of fluid through each riser in order to shut off an individual riser when the water level drops below the well point of that particular riser. The automatic regulation in the flow of water is controlled above the surface of the earth and includes a float actuated valve for preventing the pump from drawing air. The float actuated valve has a float connected to a rocker arm operating two valve seats for closing a pair of ports and also has a controlled air bleed for evacuating the riser and allowing the water to unseat the valve when the water rises around the well point.
