1800 Series Spray Heads
The #1 Irrigation Spray Head in the World
Installed in parks and backyards across the globe, Rain Bird’s 1800 Series is the #1 commercial-grade irrigation spray head brand in the world.
Chosen for its reliability, heavy-duty materials, and versatility, the 1800 Series offers a broad selection of pop up heights and nozzle combinations for watering shrubs, small lawns, and irregularly shaped planting areas.
All models feature Rain Bird’s patented pop-up mechanism with heavy-duty stainless steel spring for dependable out-of-sight retraction, plus an exclusive co-molded wiper seal for unmatched resistance to grit, pressure, and extreme environments.
The Perfect Pair for Pressure Regulation
Rain Bird’s patented Pressure Regulating Stem (PRS) saves up to a gallon of water per minute.
The 1800 PRS-45 Spray maintains optimal outlet pressure at 45 psi. For ultimate efficiency, pair with R-VAN Rotary Nozzles, which are engineered to work best at this pressure.
