Rain Bird - 1804SAMP45 - 4" 1800 Series SAM-P45 Spray Head - No Nozzle

• 4 in. 1800 Series pop-up spray head with Rain Bird Flow Optimizer Technology and Seal-A-Matic Check Valve
• PATENTED PRS pressure regulator built into the stem
• Restricts water loss by up to 70% if nozzle is removed or damaged
• Saves water and money
• Reduces possibility of accidents and property damage
• Designed for use with all Rain Bird plastic spray head nozzles
• Provides 45 psi in-stem pressure regulation for maximizing efficiency or Rotary Nozzles
• Includes Seal-A-Matic check valve preventing low head drainage of up to 14 feet of head
• Nozzle not included

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.
• Built-in Seal-A-Matic (SAM) check valve. Eliminates the need for under-the-head check valves. No parts to be installed at the site.
• 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.
• “SAM-PRS” stamped on cap for easy identification and maintenance.
