Rainbird National Sls 1804FDS 4 Inch Pop Up Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1804FDS is a professional-series pop-up spray head designed for residential and commercial irrigation systems. It features a dual spray nozzle configuration with patented close-in watering technology that promotes uniform water coverage and reduces dry spots across turf and landscaping zones. The 4-inch pop-up height suits standard lawn installations, and the 1/2-inch inlet connects to common lateral line fittings. A patented pressure-activated co-molded wiper seal keeps the riser clean during retraction, extending service life in gritty soil conditions. Licensed irrigation technicians and landscape professionals are the primary installers.

This spray head is suited for residential lawns, commercial turf areas, and landscape beds requiring full-circle coverage. The dual spray nozzle delivers even distribution from the center of the arc outward, addressing the dry-ring problem common with single-nozzle heads. The removable grit filter protects the nozzle orifice from particulate contamination in municipal and well-water systems alike. The unit ships in a package quantity of 18, making it practical for zone-level installations where multiple heads are replaced at once.

Installation Notes

Installation is performed by licensed irrigation technicians or qualified landscape contractors. Shut off the irrigation zone and relieve line pressure before removing an existing head or threading in the new unit. Use Teflon tape on the 1/2-inch male inlet threads to ensure a leak-free connection. Follow local plumbing and irrigation codes, and verify that system operating pressure is within the rated range for this nozzle type before returning the zone to service.
