ABSTRACT:
A pedal operated flushing system includes a hydraulically-actuated flush valve connected to a hydraulic fluid source by a supply line having a control valve therein. The control valve is mounted on a pocket portion of a bracket, the pocket forming an enclosure about an opening in a wall. A pedal is hinged to the bracket and normally covers the wall opening. The pedal pivots into the enclosure to actuate the control valve. A spring interposed between the pedal and control valve absorbs overtravel of the pedal toward the valve.
