Abstract
A spray system is provided for distributing fluid over a selected area through a distribution header to spray units. A control unit uses a siphon loop to continuously cycle an internal water level between two elevations. A water level float provides an output for actuating a valve effective to vary fluid pressure in the distribution header and affect a sweeping of the spray produced by the spray units. The fill rate of the control unit may be varied to change the sweeping rate of the spray through the spray units.
