Rainbird 1804HV15PR Prs Pop-up Sprinkler 15 Foot Adj

Product Description

The RAINBIRD NATIONAL SLS 1804HV15PR is a 4-inch, 1800 professional series pressure regulating pop-up sprinkler designed for residential and commercial irrigation systems. It features a 1/2-inch inlet and an adjustable spray pattern from 0 to 360 degrees with a throw distance of up to 15 feet. The unit ships with a high-efficiency (HE) rate nozzle that produces a larger droplet size and lower trajectory, reducing run times by up to 35 percent compared to standard nozzles. Licensed irrigation contractors and landscape professionals install this sprinkler as part of in-ground zone systems requiring pressure regulation at the head.

The 1804HV15PR is suited for residential lawns, commercial turf areas, and municipal irrigation zones where consistent pressure at each head is critical. Its pressure regulating system (PRS) keeps output stable regardless of supply line fluctuations, making it appropriate for systems with variable mainline pressure. This model is required by code in California, Washington, Hawaii, Colorado, and Vermont, where water-efficiency mandates apply to new and replacement sprinkler installations. Each package contains 18 units, making it practical for contractors stocking heads for zone retrofits or new installations.

Key Features

• Pressure regulating system (PRS) maintains consistent output at the head across variable supply pressures
• High-efficiency nozzle produces larger droplets and lower trajectory, reducing run times by up to 35 percent
• Adjustable spray pattern from 0 to 360 degrees covers partial or full-circle zones
• Patented pressure-activated co-molded wiper seal keeps debris out during pop-up and retraction cycles
• Stainless steel retractable spring and stainless steel reduction screw for corrosion resistance and long service life
• Removable grit filter protects nozzle from sediment without requiring full head disassembly
• Easy nozzle alignment feature speeds installation and adjustment in the field

Compatibility

Designed as an OEM-style replacement or new-installation head for 1800 series professional pop-up sprinkler systems requiring a pressure regulating, high-efficiency nozzle configuration with a 1/2-inch inlet.

Installation Notes

Installation should be performed by a licensed irrigation contractor or qualified landscape professional familiar with local water-efficiency codes. Shut off the irrigation zone valve and relieve line pressure before removing or installing any sprinkler head. Use a rotor key or flathead screwdriver to adjust the pattern arc and radius reduction screw after installation with the zone pressurized. Verify local code requirements, particularly in California, Washington, Hawaii, Colorado, and Vermont, where pressure-regulating and high-efficiency heads may be mandated for new or replacement installations.
