Abstract:
A sprinkler head assembly having off/on water flow control for turning water of f and on at said sprinkler head assembly, without interrupting water flow to any adjacent sprinkler heads, said sprinkler head assembly comprising:a) a generally upright tube which carries water from a subterranean water conduit; b) a sprinkler head body at the upper end of the generally upright tube and at least one of said body and said tube having a generally upright duct in communication with said subterranean water conduit; c) an insert located at said sprinkler head body for allowing a directionalized spray of water from the subterranean conduit through the sprinkler head; and d) off/on water flow control valve means comprising a manually actuable plug extending into said duct and being angularly located with respect to an axis of said duct for stopping water flow when the plug is in a first position in said duct such that it blocks water flow and reinitiating a flow of water to said sprinkler head assembly when said plug is in a second position which is shifted axially of said plug with respect to said first position and independently of a main control therefor, thereby allowing servicing of said sprinkler head assembly without the need of controlling water flow at the main control therefor or shutting off water flow to other sprinkler head assemblies receiving water from that subterranean water conduit.
