  • Patent number: 6367501
    Abstract: An anti-geyser shut-off valve assembly for a water sprinkler irrigation system. It has a valve housing, a valve member, a coil spring, and a push nut that would be installed on the elongated shaft member of the valve housing for restricting the distance that the valve member may be biased away from a valve housing. When a sprinkler housing is mounted above the shut-off valve assembly and is operating properly, there is minimal obstruction to the water flow passing therethrough. If the sprinkler head or riser is broken off, the uncontrolled geyser of water will be automatically shut off and a thin stream of water would be sprayed upwardly to function as a flag identifying that the sprinkler head requires repair.
