ABSTRACT:
An improved method for installing lawn sprinkler systems wherein a flexible interconnection line is inserted between the sprinkler head and the water supply line. The flexible interconnection line is preformed having a bend at each end thereof, the bends being orthogonal to each other and to the axis of the interconnection here. This arrangement of bends at the end of a flexible section permits the flexible section to be maintained in close parallel relationship to the water supply line to minimize the width of the trench which must be dug for emplacement of the water supply line beneath the surface of the ground. The preformed interconnection line is also provided with preformed threads at the end so that threaded coupling may be readily made to the water supply line as well as the sprinkler head. This arrangement of threaded coupling permits ready replacement of parts should damage ever occur in the line.
