The Perfect Pair for Pressure Regulation

Rain Bird’s pressure-regulating stem (PRS) saves up to a gallon of water per minute.

We offer three perfectly paired combinations of PRS spray bodies and high-efficiency nozzles. Each pair is designed to work together to give you the best possible performance across your entire irrigation system — all while saving water.

All 1800s:

  • Co-molded wiper seal provides unmatched resistance to grit, pressure, and the environment
  • Constructed of time-proven UV-resistant plastic and corrosion-resistant stainless steel parts, ensuring long product life
  • Precision-controlled flush at pop-down clears debris from the unit, assuring positive stem retraction in all soil types
  • The two-piece ratchet mechanism allows easy nozzle pattern alignment and provides added durability
  • Five-Year Trade Warranty

1800 SAM Series:

  • Built-in Seal-A-Matic (SAM) check valve. Eliminates the need for under-the-head check valves
  • Ideal for use in areas with changing elevations
  • Traps water in lateral pipes in elevation changes of up to 14 feet (4.2 m), eliminating low head drainage at the base of slopes or hillsides
  • Reduces wear on system components by minimizing water hammer during start-up

1800 PRS Series:

  • All Rain Bird pressure regulating spray bodies are WaterSense certified by ICC-ES
  • PATENTED PRS pressure regulator built into the stem. No parts are to be installed at the site. It saves time and money
  • Maintains constant outlet pressure at 30psi (2.1 bar) or 45 psi (3.1 bar) at varying inlet pressures regardless of nozzles used
  • 30 psi is recommended for optimal spray nozzle performance, 45 psi is recommended for optimal rotary nozzle performance

1800 SAM-PRS-30 and SAM-PRS-45 Series

  • Combines Seal-A-Matic check valve and PRS-30 or PRS-45 for best performance
  • Ideal for sloped applications that have fluctuating or high pressure
