ABSTRACT:
An improved tank flushing system is described for use with a toilet bowl or other flushed system. An inlet valve for the tank includes a valve stem which is opened by a flush lever and which is closed by the force of the inflowing water under the control of a float. The outflow of the flushing water from the tank for the flushing operation is controlled by a flush valve comprising a flexible sealing member mounted on the tank bottom and coupled to a float. The flush valve is opened as the sealing member is lifted by the flush lever and remains opened under the control of the float until a predetermined volume of flush water has flowed from the tank.
