The number 1 irrigation pop-up nozzle in the world
Rain Bird's 1800 Series, installed in parks and gardens around the world, is the #1 irrigation pop-up nozzle in the world.

Selected for its reliability, heavy-duty materials and versatility, the 1800 Series offers a wide range of set-up heights and nozzle combinations for watering shrubs, small lawns and irregularly shaped planting areas.

All models feature Rain Bird's patented set-up mechanism with a heavy-duty stainless steel spring for reliable hidden retraction, and an exclusive dual-material molded wiper for unmatched resistance to grit, pressure and extreme environments.

Perfectly tuned pressure regulation
Rain Bird's pressure regulation stems (PRS) save up to 1 gallon (3.78 liters) of water per minute.

We offer three perfectly matched combinations of PRS pop-up sprinklers and high-efficiency nozzles. Each combination ensures the best possible performance from your entire irrigation system. All while saving you additional water.

All 1800s:
Cast from two materials, the wiper offers unmatched resistance to grit, pressure and outside elements.
Made of proven UV-resistant plastic and corrosion-resistant stainless steel parts for long life.
Automatic flush function during riser retraction removes dirt and debris, ensuring reliable retrieval of risers even in difficult ground conditions.
Two-piece ratchet mechanism ensures easy adjustment of spray direction and long service life.

1800® SAM Series
Integrated Seal-A-Matic™ (SAM) check valve. Eliminates the need for check valves in the sprinkler body.
Ideal for use in areas with varying elevations.
Keeps water in the branch lines at elevation changes of up to 14 feet (4.2 m), preventing drainage of low-lying sprinkler heads at the base of slopes or hillsides.
Reduces wear on system components by minimizing water hammer during startup.

1800® PRS Series
All Rain Bird pressure regulating sprayers are certified by ICC-ES WaterSense.
PATENTED PRS pressure regulator integrated into the riser. Pre-assembled unit ready for installation. Saves time and money.
Maintains constant outlet pressure at 30 psi (2.1 bar) or 45 psi (3.1 bar) at various inlet pressures, regardless of nozzles used,
2.1 bar (30 psi) is recommended for optimum spray nozzle performance and 3.1 bar (45 psi) for optimum rotary nozzle performance.

Series 1800 SAM-PRS-30 and SAM-PRS-45
Combines Seal-A-Matic check valve and PRS-30 or PRS-45 for best performance.
Ideal for applications on slopes with fluctuating or high pressure.
