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 pressure-regulating stem (PRS) saves up to a gallon of water per minute.

We offer three perfectly paired combinations of PRS spray bodies and high-efficiency nozzles. Each pair is designed to work together to give you the best possible performance across your entire irrigation system — all while saving water.
