The Rain Bird RD04SP30FN RD1800 4 in. pop-up spray is built for harsh irrigation environments and reclaimed water systems. It combines a 30 PSI pressure-regulating stem (PRS), Seal-A-Matic (SAM) check valve, and Flow-Shield technology for reliable, water-saving performance.

  • Durable construction with UV-resistant plastic, corrosion-resistant stainless steel parts, and a Triple-Blade Wiper Seal to prevent stick-ups and handle debris.
  • Built-in PRS pressure regulator helps reduce misting and saves approximately one gallon per minute per spray at high pressures.
  • SAM check valve prevents low-head drainage and allows installation on slopes and uneven terrain; non-potable models include a purple cap and built-in warnings.
  • Flow-Shield technology provides a low-flow service indication stream to quickly detect broken or missing nozzles and conserve water.
  • Fits 1/2 in. female threaded inlet; compatible with Rain Bird nozzles including MPR, VAN, U-Series and rotary nozzles (nozzle not included).
  • Dimensions: 4 in. pop-up height, 6 in. body height, 2 1/4 in. exposed diameter. Operating range: spacing 2.5–24 ft; pressure 15–100 psi (SAM models).

Designed for easy maintenance, the RD1800 allows top-removal servicing and includes debris pockets, a pre-installed Pop-Top flush plug, and a reinforced ratchet for reliable alignment. Backed by Rain Bird's proven design and a five-year trade warranty, this spray head delivers long-term performance for landscapes, commercial sites, and reclaimed water applications.
