Rain Bird 5004 Part-Circle Rotor 4 in. Riser with SAM Check Valve

Built for consistent performance on sloped and uneven landscapes, the Rain Bird 5004 Part-Circle Rotor with SAM Check Valve delivers uniform watering while actively preventing low-head drainage. With Rain Bird’s proven Rain Curtain nozzle technology and an integrated Seal-A-Matic (SAM) check valve, this rotor helps maintain system efficiency, reduce water waste, and ensure clean start-ups every cycle—making it a dependable choice for residential and light commercial irrigation zones. Designed with contractors in mind, this 4 in. pop-up rotor offers adjustable arc coverage from 40° to 360°, allowing precise watering control without replacing heads. The self-flushing arc adjustment port and tapered stem with a multi-function wiper seal help protect internal components from debris, extending product life and minimizing maintenance. Large-droplet Rain Curtain nozzles improve wind resistance while delivering even distribution from the head to the edge of the radius. The integrated SAM check valve holds back water in lateral lines, preventing puddling, runoff, and erosion in low areas after system shutoff. Altogether, the Rain Bird 5004 PC SAM combines durability, water efficiency, and flexible adjustment to support reliable irrigation performance where it matters most.
