The Toro 570Z Series spray heads are the ideal choice when it comes to meeting the needs of a WaterSense-certified product. The 3 in. Pressure-Regulating spray head has a variable arc nozzle that adjusts from 0 - 360 degrees and has a 15 ft. radius. Toro's factory-installed pressure regulator eliminates water misting and fogging at the nozzle which can lead to rapid evaporation or water being blown away from the intended irrigation area. The in-stem pressure regulator provides a steady outlet pressure of 30 PSI along with consistent spray head performance across the zone. Heavy-duty stainless-steel spring and seal prevents water waste and ensures proper retraction. Zero flush means no water loss at system start-up.
