The Benefits of Rain Bird PRS Spray Heads

 

Rain Bird PRS vs. the Competition

  • PATENTED PRS pressure regulator built into the stem. No parts to be installed at the site. Saves time and money.
  • Maintains constant outlet pressure at 30psi (2.1 bar). Spray nozzles perform best at 30psi. 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.

Rain Bird 1800-PRS Sprays reduce flow to save water and improve performance versus non-PRS competitive sprays.

  • Restricts water loss by up to 70% if nozzle is removed or damaged. Saves water and money. Reduces possibility of accidents and property damage. Recommended for vandal-prone areas.
  • 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.

Patented pressure regulator in the stem compensates for high or fluctuating water pressure.

  • 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.Designed for use with all Rain Bird spray head nozzles. Smart Approved WaterMark
  • Designed for use with all Rain Bird plastic spray head nozzles.
  • “PRS” stamped on cap for easy identification and maintenance.
  • Five-year trade warranty.
