Beginning on October 1st, 2020, any spray bodies purchased, installed, or replaced in the state of California must include an integral pressure regulator system (PRS). A pressure regulator is a device that maintains constant operating pressure immediately downstream from the device, given higher upstream pressure.


Spray bodies must meet performance requirements that align with WaterSense requirements for spray sprinkler bodies. From here on out, we will be stocking only PRS spray bodies. All PRS models sold by GreenStar will meet the necessary requirements to comply with this law.
