ABSTRACT:
An irrigation system includes one or more valve assemblies which are connected in series to a pressurized source of water. Each valve assembly includes a cylindrical housing, a ball valve, an inlet and two outlets with one outlet generally opposite from the inlet in a lower portion of the housing. The other outlet is disposed in an upper portion of the housing and adapted to direct water to an area of ground for irrigation. A pit and float are associated with each valve assembly and arranged so that some of the irrigation water will flow into the pit and raise the float. The float is connected spring biasing element and a U-shaped pivotal member. This U-shaped pivotal member maintains a spring in a compressed or energy-stored condition and releases the spring biasing element when the float reaches a predetermined level so that the ball valve will spring upwardly to close the upper outlet and redirect the water to another assembly. Water pressure will then maintain the valve in that position.
