TROUBLESHOOTING GUIDE

Installed in parks and backyards across the globe, Rain Bird's 1800 Series is the #1 commercial-grade irrigation spray head brand in the world.

Chosen for its reliability, heavy-duty materials, and versatility, the 1800 Series offers a broad selection of pop up heights and nozzle combinations for watering shrubs, small lawns, and irregularly shaped planting areas.

All models feature Rain Bird's patented pop-up mechanism with heavy-duty stainless steel spring for dependable out-of-sight retraction, plus an exclusive co-molded wiper seal for unmatched resistance to grit, pressure, and extreme environments.

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.

Features:

  • All Rain Bird pressure regulating spray bodies are WaterSense certified by ICC-ES

  • PATENTED PRS pressure regulator built into stem. No parts to be installed at the site. Saves time and money

  • Maintains constant outlet pressure at 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
  • Nozzle not included
  • 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 unit, assuring positive stem retraction in all soil types

  • Two-piece ratchet mechanism allows easy nozzle pattern alignment and provides added durability

  • Five-Year Trade Warranty

Additional features:

  • Maintains constant outlet pressure at 45psi. Ensures maximum nozzle performance, even with varying inlet pressures. Maintains constant pressure regardless of nozzles used.
  • Unlike competitive PRS sprays, Rain Bird PRS sprays adjust to fluctuating pressure, optimizing flow and promoting a more consistent spray pattern.
  • Ensures consistent performance throughout zone if nozzle is removed or damaged. Keeps plant life covered by other spray heads properly irrigated.
  • Ends misting and fogging caused by high pressure. Stops water waste. Ensures necessary watering occurs in high pressure or wind conditions.
  • Traps water in lateral pipes in elevation changes of up to 14 feet (4,2 m). Reduces wear on system components by minimizing water hammer during start-up.
  • Prevents drainage from spray heads at lower elevations. Stops water waste. Ends landscape damage due to flooding and/or erosion.
  • Even stronger retract spring to accommodate elevation changes up to 14 feet (4,2 m). One of the strongest springs in the industry.
  • Co-molded, pressure-activated, multi-functional wiper seal assures positive seal without excess “flow-by” which enables more heads to be installed on the same valve.
  • All sprinkler components are removable from the top without special tools, providing for quick and easy flushing and
  • maintenance of the sprinkler.
  • Constructed of time-proven UV-resistant plastic and corrosion resistant stainless steel parts, assuring long product life.
