The amount and intensity of flow from most variable-pressure hose nozzles are regulated by having to turn the tip of (or a knob on) the nozzle and squeeze a handle/trigger. For one with a hand impairment, this can be difficult to do. A Hand Lever Hose Nozzle, (sometimes called a "fireman's nozzle"), which is pushed/pulled to regulate flow rather than squeezed/twisted, may prove to be a good alternative, including for persons with a hand prosthesis. Among the common brands of the Hand Lever Hose Nozzle are: Melnor, Aqua-Plumb, Camco, Carrand, Flex-Hose, Gilmour, Melnor, and Orbits.
