Rainbird National Sls 1802HDS Pop Up Spray Head Half Circle

Product Description

The RAINBIRD NATIONAL SLS 1802HDS is a professional-series pop-up spray head engineered for residential and commercial irrigation systems. Designed to deliver half-circle coverage, this unit features a dual spray nozzle and patented close-in watering technology that promotes uniform water distribution and eliminates dry spots within the spray pattern. The pressure-activated co-molded wiper seal keeps debris out of the riser mechanism during retraction, extending service life in field conditions. A removable grit filter protects the nozzle from particulate buildup, and a stainless steel retractable spring ensures consistent pop-up and retraction cycles. The 0.5-inch inlet connects directly to standard irrigation lateral lines.

This spray head is suited for turf and landscape bed applications where precise zone coverage is required. The half-circle pattern makes it appropriate for borders, edges, and corners where full-circle heads would overspray onto hardscapes or structures. A stainless steel arc-adjustment reduction screw allows field techs to fine-tune the spray arc without specialized tooling, and the easy nozzle alignment feature simplifies head replacement and servicing during routine maintenance visits. Irrigation contractors and landscape professionals typically install this head in both new construction and retrofit irrigation projects.

Installation Notes

Installation is performed by licensed irrigators or irrigation contractors following local and state irrigation codes. Shut off the zone valve and depressurize the lateral line before removing or installing the head. Hand-tighten the inlet connection to the lateral fitting, then use strap-style tools as needed to avoid cracking the body. After installation, verify pop-up height, spray arc, and nozzle alignment before backfilling or closing the trench.
