Rainbird National Sls 1804QDS Quarter Circle Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1804QDS is a professional-series quarter-circle pop-up spray head designed for residential and commercial irrigation systems. It features a dual spray nozzle with close-in watering coverage to deliver uniform water distribution and reduce dry spots. The 4-inch pop-up height suits standard turf and ground cover installations. Key construction details include a pressure-activated co-molded wiper seal to keep debris out of the body, a stainless steel retractable spring for reliable pop-up action, and a stainless steel arc-adjustment reduction screw. The 1/2-inch inlet threads into standard lateral lines. Licensed irrigation contractors and landscape professionals are the typical installers.

This spray head is suited for quarter-circle coverage zones in residential lawn, landscape bed, and light commercial turf applications. The dual spray nozzle pattern addresses the close-in dry zone that single-pattern nozzles often miss, supporting more even coverage across the spray radius. The removable grit filter protects internal components from particulate in the water supply, extending service intervals. It ships in a package quantity of 18 units per package, making it practical for multi-head zone installations.

Installation Notes

Installation is typically performed by licensed irrigation contractors or qualified landscape professionals. Shut off system water supply and depressurize the lateral line before threading the head into the riser or swing joint. Hand-tighten the 1/2-inch inlet connection to avoid cracking the body, then confirm pop-up and retraction function before backfilling. Verify local code requirements for irrigation system design and backflow prevention under applicable plumbing codes.
