Rain Bird 1812 Spray Body NSI 12 in. Pop Up with PRS30 Pressure Regulator and SAM Check Valve

Maintain consistent spray performance and reduce water waste with the Rain Bird 1812 Spray Body NSI, engineered to deliver reliable pressure regulation and superior low-head drainage protection. By combining a built-in PRS30 pressure regulator with a Seal-A-Matic (SAM) check valve, this spray body helps ensure uniform nozzle output while preventing runoff and pooling on slopes—resulting in healthier landscapes and more efficient irrigation. Designed for professional-grade irrigation systems, the 1812 Spray Body features a rugged construction and a pressure-regulated stem that maintains an average 30 PSI at the nozzle, even when inlet pressures fluctuate. This controlled pressure improves spray uniformity, reduces misting, and extends nozzle life. The integrated SAM check valve holds back water after shutdown, minimizing erosion and water loss in elevation changes of up to 14 ft. With a full 12 in. pop-up height and compatibility with Rain Bird spray nozzles, this unit delivers dependable coverage across a wide range of residential and commercial applications, making it a trusted choice for long-term irrigation performance
