ABSTRACT:
As a method to conserve water, a flow controllable shower arm or an adaptive fitting attachment to an existing shower arm having an unobtrusive and relatively unobservable tool-operative feature, which allows authorized personnel in possession of a particular tool to control the amount of water flow into and through a downstream showerhead. In particular, a small valve is located in the shower arm or the adaptive attachment and has a threaded plug which can extend into or out of the axial water duct of the arm or rotate a maximum of 90 degrees within the arm to thereby block water flow or permit water flow. A tool-receiving end is provided at the outer portion of the plug to eliminate or at least minimize access to said flow control by the person taking the shower.
