Maximum Water Savings
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 four 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.
