About the Rain Bird 4" 1800 SAM-PRS Series Pop-Up Sprinkler, No Nozzle - 1804SAMPRS (A44915)
Customizable spray for any landscape!
The Rain Bird 1804SAMPRS pop-up sprinkler combines two essential features—Seal-A-Matic (SAM) check valve and Pressure Regulating Stem (PRS)—to deliver consistent, efficient irrigation in both level and sloped landscapes. The built-in SAM check valve prevents drainage from low-head sprinklers by holding up to 14 feet of elevation change, which eliminates runoff, puddling, and water waste after each irrigation cycle.
With its integrated PRS regulator, the 1804SAMPRS maintains a constant 30 psi outlet pressure, regardless of fluctuations in system pressure. This steady output helps maximize the performance of any Rain Bird nozzle (sold separately), reducing misting and overspray while promoting uniform water distribution. The result is healthier turf and plant beds, reduced water bills, and compliance with water-saving landscape codes. Ideal for both residential and commercial irrigation systems, it delivers precision watering without the need for additional pressure-regulating devices.
Moreover, the 4-inch pop-up height is perfectly suited for flat turf areas or shorter groundcover, while the 1/2-inch NPT inlet ensures easy installation with standard riser fittings. A pressure-activated wiper seal and stainless steel spring provide smooth, leak-resistant pop-up and retraction, even in dirty or debris-prone environments. Maintenance is simple thanks to its top-serviceable design, allowing quick access to internal components without removing the entire body. The Rain Bird 1804SAMPRS pop-up sprinkler delivers long-term performance and peace of mind for any water-conscious irrigation plan.
