Rain Bird LG-3 Impact Sprinkler 26–36 ft Full- or Part-Circle — 3" Pop-Up, 3 GPM Nozzle

The Rain Bird LG-3 is a professional-grade, in-ground pop-up impact sprinkler delivering reliable full- or part-circle coverage from 26 to 36 feet with a preinstalled 3 GPM matched-precipitation nozzle.

Designed for residential and light-commercial underground irrigation, the LG-3 pairs heavy-duty impact mechanics with a 3" pop-up height so the head clears tall turf and retracts when not in use. Built to tolerate hard water and reclaimed or well water, this model uses a double-weighted brass PJ arm and diffuser screw to reduce splash, increase throw, and maintain consistent application across a wide pressure range (25–50 psi).

How does the LG-3 maintain even watering across a lawn?

The LG-3 uses a diffuser screw and a brass weighted PJ spray guide arm to break water into smaller droplets and control stream shape, improving uniformity while preventing side-splash onto paths and buildings. The arm’s double weights slow rotation for longer throw and steadier distribution.

• Preinstalled 3 GPM matched-precipitation nozzle for consistent application
• Diffuser screw reduces droplet size and allows up to 25% radius reduction
• Double-weighted arm yields slower, more even rotation
• Pattern adjustment from 20° to 360° for tuning overlap

Will this sprinkler handle hard or reclaimed water?

The LG-3 is engineered with heavy-duty materials and a robust impact mechanism that resist clogging and corrosion from mineral-rich or "dirty" water sources. That makes it a solid option for systems using well water or reclaimed water where other nozzles might fail.

• Industrial-strength impact drive designed for heavy-mineral content
• Brass spray guide arm resists corrosion
• Reliable operation in reclaimed or low-quality water conditions

How adjustable and easy is installation and servicing?

The LG-3 offers infinite pattern adjustment between 20° and 360°, a 1/2" female inlet on the side or bottom, and a rolled-lip case that helps set proper installation height and limits backwash. For simplified field adjustments and repairs, Rain Bird supplies a dedicated adjustment wrench (sold separately) to change sector, nozzle, and other settings.

• Infinite arc adjustment, part circle to full circle
• Side or bottom 1/2" female connection for flexible plumbing
• Rolled-lip body minimizes grass intrusion and eases installation height control
• Compatible with Rain Bird adjustment wrench (Model 420644TLWR, sold separately)

What spacing and pressure work best for this model?

The LG-3 is designed to operate across a 25–50 psi range and perform well when heads are spaced 26 to 36 feet apart, depending on lawn layout and overlap requirements. Use the nozzle’s matched-precipitation flow and pattern tuning to establish even coverage without overwatering.

• Designed for 25–50 psi operating pressures
• Recommended spacing: 26' to 36' depending on overlap
• 3 GPM nozzle establishes predictable precipitation rate for system design

Who is this for: The Rain Bird LG-3 suits homeowners, landscapers, and light-commercial installers seeking a durable pop-up impact sprinkler that handles tough water conditions, provides adjustable full- or part-circle coverage, and blends industrial reliability with easy installation. It’s particularly useful for high-traffic turf that needs to remain clear when irrigation is off and for systems using reclaimed or well water where clog-resistant performance is important.
