The ability to regulate water pressure is crucial to overall system efficiency. The brown-capped PRS30 takes all the rugged and reliable features of the Pro-Spray body and delivers efficient pressure regulation by keeping water pressure at a constant 30PSI. The built-in regulator is proven to reduce water waste and promote healthier root zones, because water is delivered at the optimum pressure for spray nozzles. The PRS30 is compatible with both fixed-arc and Pro Adjustable Nozzles, and is available in Shrub, 4 in., 6 in. and 12 in. riser heights. It is recommended for both residential and commercial applications.
