ABSTRACT:
Improved apparatus for flushing particulate matter from the pipeline of a center pivot irrigation system. The improved apparatus provides a length of downwardly extending pipe interposed in the pipeline in the immediate vicinity of or contiguous to the outermost mobile tower assembly of a plurality of such assemblies transporting the pipeline, permitting an operator standing on the ground to open the pipe during flushing. The downwardly extending pipe includes a restrictive opening for limiting the rate at which water is released from the pipeline during flushing.
