Rain Bird 1812-SAM-P45 12 in pop-up spray head delivers reliable, water-saving irrigation for residential and commercial landscapes. It combines a built-in 45 PSI pressure regulator (P45) with Rain Bird's Seal-A-Matic (SAM) check valve to prevent low-head drainage on slopes and reduce runoff. Designed for durability, the body is constructed from UV-resistant plastic with corrosion-resistant stainless-steel internal components for long service life. No nozzle is included so you can specify the nozzle type and radius that matches each zone.

  • Built-in 45 PSI PRS (P45) maintains consistent nozzle pressure for efficient coverage and optimized spray performance.
  • Seal-A-Matic (SAM) check valve prevents low-head drainage up to 14 ft, saving water and preventing puddling on slopes.
  • 12 in pop-up; 16 in body height; 2-1/4 in exposed diameter; 1/2 in female threaded inlet for standard connections.
  • Top-serviceable design allows quick maintenance without digging; compatible with Rain Bird plastic spray nozzles (nozzles sold separately).
  • Durable UV-resistant plastic construction and corrosion-resistant stainless-steel parts resist weathering and extend product life.
  • Operating pressure range 25-70 PSI; recommended spacing varies by nozzle (commonly 13-24 ft).

Choose the 1812-SAM-P45 when you need a high-performing pop-up spray that controls pressure, prevents low-head drainage, and simplifies maintenance. Ideal for sloped terrain, turf, and landscape beds where reliable, efficient irrigation is required.
