The Rain Bird 1806SAMP45 6-inch 1800 Series SAM-PRS pop-up spray head delivers consistent, efficient irrigation in areas with variable elevations and fluctuating water pressure. It combines a built-in 45 PSI pressure regulator with the Seal-A-Matic check valve to maintain nozzle performance while preventing low-head drainage.
