The Toro 570Z Pro Series Fixed Pop-up Pressure-Regulated Sprinkler (body only) is the ideal choice when it comes to meeting the needs of a WaterSense-certified product. With the pressure-regulating spray heads, 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. From the first head to the last head, the in-stem pressure regulator provides a steady outlet pressure of 30 PSI along with consistent spray head performance across the zone. This sprinkler body also features a built in. X-Flow shut-off device that eliminates water loss when the sprinkler nozzle is damaged or removed.
