Rainbird 1804HDSP25 Prs Pop-up Spray Head 25-pack

Product Description

The RAINBIRD NATIONAL SLS 1804HDSP25 is a 4-inch, pressure-regulating (PRS) pop-up spray head from the 1800 Professional Series, sold in a 25-unit pack. It features a 1/2-inch inlet and delivers a 180-degree half-circle pattern with a throw distance of up to 15 feet. The integrated Dual Spray nozzle provides close-in watering coverage, promoting uniform distribution and reducing dry spots. Designed for professional landscape irrigation installers, this head is required by code in California, Washington, Hawaii, Colorado, and Vermont.

This sprinkler head is suited for residential and light commercial turf and landscape irrigation systems. The half-circle pattern and 15-foot radius make it appropriate for perimeter zones, property edges, and rectangular turf sections. The 25-pack format is sized for contractor use, reducing per-unit cost on multi-head installations. The PRS feature regulates pressure at the head, making it effective in systems with variable or higher inlet pressure.

Installation Notes

Installation is typically performed by licensed irrigation contractors or qualified landscape professionals. Shut off the irrigation system supply valve before replacing or installing heads. Hand-tighten the inlet connection to avoid cracking the body; use thread-seal tape on threaded fittings. Verify zone pressure is within the rated range for the PRS feature to operate correctly, and flush the lateral line before installing the nozzle.
