GeyserStop sprinkler valve provides an automatic shut-off for sprinkler systems and operates without wires or flow-monitoring devices. The valve attaches to an existing system between the water supply line and the sprinkler head. When the sprinkler head or riser is broken away, the valve automatically activates and stops the flow of water at the broken head. The valve reportedly works with all types of sprinkler heads. Available in 1/2-, 3/4-, and 1-inch models, the valve self-resets upon use.
