Each flexible tube has a nozzle with 3 separate orifices. Each orifice is angled outward at 5 degrees so that when the 3 streams break up and fall 20 feet away the water covers an area approximately 6 feet in diameter. (approx. 28 square feet per tube)(approx. 336 square feet per Noodlehead) Streams are thrown approximately 20 feet at 45 P.S.I., 30 feet maximum at 80 P.S.I. Each Noodlehead flows approximately 222 gallons per hour (GPH) or 3.7 gallons per minute. Each Noodlehead is pressure tested to 125 P.S.I.
