The Rainmaker syringe nozzle is designed specifically for syringing and spot watering putting greens. The nozzle delivers large, gentle droplets that fall like rain in a broad fan pattern. The open orifice design will not plug with grass clippings, soil or sand, as will most conventional shower nozzles. The Rainmaker nozzle also works exceptionally well for hand watering of lawns and gardens around homes, businesses, and recreational areas. Rainmaker nozzles are available in either 3/4-inch or 1-inch hose end connections and the control valve is optional. Like all Precision products the rainmaker is made of durable brass & stainless steel components. Rainmaker Flow Rates are Pressure (PSI)/Flow Rate (GPM) 10/8.9; 20/12.2; 30/14.9; 40/16.5; 50/18.0; 60/20.0; 70/21.5; 80/23.0; 90/24.3; 100/25.1
