Perfect for watering gardens, flower beds, ground cover, and hillsides, the Micro Spray Jet provides low volume overhead irrigation. Best used on a rigid riser with stake. Fan spray emits water in a half-circle pattern at up to 12.9 GPH, radius of up to 9.0 ft. (at 15-50 PSI). To install, screw jet onto riser and connect 1/4 in. supply tubing to the inlet barb on stake. The Micro Spray Jet operates at low pressures and is not intended for lift off-so we recommend using a pressure regulator at the water source to reduce output and help keep the jet in place. Made of polyethylene treated with UV inhibitors.
