Abstract: A readily expandable self-cleaning progressive spray system is provided. The system includes a fluid inlet and a series of spray fittings each having a self-sweeping spray nozzle, a timing mechanism, and a pass-through valve. The series of spray fittings are connected in fluid communication to the water inlet such that the fluid passes into and through the spray nozzle of each spray fitting until its timing mechanism expires which subsequently activates its pass-through valve which directs the fluid on to the next spray fitting. The spray fittings include a reset mechanism which resets the pass-through valves in order to allow the valves to iterate through the desired pattern again after completing one cycle.
