Rain Bird - 1812P45 - 12" 1800 Series Pressure Regulated P45 Spray Head - No Nozzle

• 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.
