Rain Bird 1804APPR25 4" Pop-Up Spray Head PRS 8–15 ft Adjustable 0°–360°

The Rain Bird 1804APPR25 is a commercial-grade 4" pop-up spray head with built-in pressure regulation that delivers adjustable 0°–360° coverage from 8 to 15 feet while cutting misting and over-spray.

This 1800 Series PRS (Pressure Regulating Spray) model combines a factory-set 30 psi regulator with a removable adjustable-pattern nozzle and rugged components designed for long service life. Engineered to preserve water and maintain consistent spray performance even when supply pressure fluctuates or wind conditions challenge distribution, this head is widely used in parks, commercial landscapes and residential systems that demand reliability and efficient water use.

How does the built-in pressure regulation help my irrigation system?

The internal regulator keeps water pressure near 30 psi at the nozzle, preventing misting and reducing water lost to over-spray. That stable pressure produces a more uniform spray pattern and can allow more sprinklers per zone without excess flow-by.

• Maintains ideal nozzle pressure for consistent radius and droplet size
• Reduces mist and wind drift for better water delivery
• Supports water savings by minimizing wasted spray
• Meets pressure regulation requirements in many U.S. states and DC

What adjustment options are available on the 1804APPR25?

This pop-up comes with a preinstalled adjustable-pattern nozzle you can rotate from 0° to 360° and a top-access screw to fine-tune throw distance from 8' to 15'. No special tools are needed to change or align parts; the ratcheting mechanism and captured screw make field adjustments quick and secure.

• Textured collar for easy grip when wet or gloved
• Physical left-edge indicator for accurate pattern positioning
• Stainless-steel top screw for distance trimming without nozzle removal
• Nozzle and components removable from the top for fast servicing

What construction features improve durability and maintenance?

Rain Bird built the 1804APPR25 with corrosion-resistant plastics and stainless-steel hardware plus a heavy-duty spring to guarantee reliable retraction. Its co-molded wiper seal and multi-function pressure-activated seal limit internal leakage and keep grit out for longer service intervals.

• Co-molded wiper seal in an encased cage for grit resistance
• Heavy-duty stainless-steel spring ensures flush retraction
• Tapered pop-up neck and controlled flush action remove debris
• White medium mesh filter screen protects nozzle from clogging

Can I mix this head with other Rain Bird nozzles and models?

Yes — the 1804APPR25 uses Rain Bird’s Matched Precipitation Rate concept so it performs consistently when combined with other fixed and adjustable-rate heads. It’s part of the 1800 family, which offers multiple pop-up heights and nozzle types compatible across the series.

• Matched precipitation for uniform watering with other 1800 nozzles
• Interchangeable nozzles and top-removable internals for easy upgrades
• Available in other pop-up heights across the 1800 PRS lineup

Who is this for: The Rain Bird 1804APPR25 is aimed at landscape pros, property managers and homeowners who need a dependable spray head that reduces waste and maintains even coverage. It’s especially suitable where higher supply pressures, wind exposure, or strict local pressure-regulation rules exist, and for anyone who wants a serviceable, long-lived pop-up that’s easy to adjust and maintain.
