Pop the spray nozzle 6 inches above the lawn with the Rain Bird 1806 PRS-45 Spray Head. The taller pop-up clears longer turf, ornamental grasses, and groundcover that swallow a standard 4 in head. Built-in PRS regulator inside the stem holds every emitter on the zone at a clean 45 psi outlet pressure — no misting at the end of the line, no weak coverage at the far edge, and up to 70% flow restriction if a nozzle is damaged or missing. Designed for use with all Rain Bird plastic spray nozzles, including R-VAN rotary nozzles at their optimal 45 psi performance point.

Why Irrigation Pros Pick This Body

• 6 in pop-up height (15.2 cm) — clears taller turf, groundcover, and ornamental beds that hide 4 in heads
• Patented PRS pressure regulator built into the stem — constant 45 psi outlet regardless of inlet pressure
• 45 psi is the optimal operating pressure for Rain Bird R-VAN rotary nozzles
• Restricts flow up to 70% if a nozzle is removed or damaged — cuts water loss and protects the rest of the zone
• Eliminates misting and fogging caused by high inlet pressure
• Compatible with all Rain Bird plastic spray nozzles
• EPA WaterSense certified — meets state PRS requirements
• “PRS-45” stamped on cap for easy ID during maintenance
• Five-year trade warranty

Sizing Up vs Down

This is the 6 in pop-up version. The same body is also available in 4 in (model 1804P45) for standard lawn-edge zones, and 12 in (model 1812P45) for tall plantings and shrub beds. The PRS-45 pressure regulation is identical across all three.

Note: This is the body only — choose your Rain Bird nozzle (R-VAN, MPR, or U-series) separately based on the spray arc and radius needed for the zone.
