ABSTRACT:
A rotary sprinkling system which is configured to minimize the accumulation and detrimental effects of debris, and which comprises a pop-up nozzle head secured to an inner housing slidably received within an outer housing and retained by the compressive force of a spring, such inner housing enclosing an impeller driven transmission subjected to only low pressure drops and having a speed-reducing gear train isolated from water flow, a simplified and easily adjustable direction controlling mechanism substantially inaccessible to intermeddlers, and a manually adjustable by-pass throttle to control the flow velocity of water driving a water-wheel impeller.
