Abstract: A flow control assembly designed to regulate flow of water from a showerhead through a foot operated and fluid actuated valve assembly. The valve assembly is disposed upstream of a flow of water issuing from the showerhead and a variable volume chamber is mounted on the floor or base of a conventional receptacle such as a bathtub. Foot pressure applied to the variable volume chamber controls the flow of actuating fluid into and out of driving contact with the valve assembly thereby positioning the latter between a valve open and a valve closed position.
