Description

Reach over established shrubs, perennial beds, and ornamental grasses with the Rain Bird 1812 PRS-45 Spray Head. The 12 in pop-up height clears tall plantings that swallow a 4 or 6 in body, putting the nozzle above the canopy where the water needs to land. 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 Landscape Pros Pick This Body

  • 12 in pop-up height (30.5 cm) — clears the canopy of established shrub and perennial beds
  • 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 Down

This is the tallest 12 in pop-up version, sized for shrub and perennial beds. The same body is also available in 4 in (model 1804P45) for standard lawn-edge zones, and 6 in (model 1806P45) for taller turf and groundcover. 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.
