The No More Geyser NMG-43 is a replacement riser pin for the NMG-49 system. Install the NMG-43 directly into the water supply line, with a retaining pin held in place by the sprinkler head. When the sprinkler head moves, the retaining pin moves out of the way, and the water pressure causes the ball to seat in the valve fitting – stopping the flow of water through the riser.
