Rain Bird 1804HDS-25 Pop-up Sprinkler Head Half Circle

Product Description

The RAIN BIRD 1804HDS-25 is a professional-grade pop-up sprinkler head designed for residential and commercial irrigation systems. It features a dual spray nozzle with a half-circle coverage pattern, making it well suited for edges, borders, and perimeter turf areas. The unit incorporates Close-In watering technology for uniform water distribution that reduces dry spots near the head. A co-molded wiper seal protects the internal components and extends service life. A heavy-duty stainless steel spring ensures consistent, full retraction after each cycle. Licensed irrigators and landscape contractors are the primary installers.

This sprinkler head is used in residential lawns, commercial turf areas, and landscape beds where half-circle coverage is required. The 4-inch pop-up height makes it appropriate for turf applications where grass height stays within standard mowing ranges. A top-adjustment screw allows the technician to reduce spray distance without removing the head or changing nozzles. Nozzle changes require no tools, which speeds up service calls and routine maintenance.

Installation Notes

Installation is performed by licensed irrigators or qualified landscape contractors in accordance with local irrigation codes and water authority requirements. Shut off the irrigation zone and relieve line pressure before removing or replacing the head. Ensure the riser is threaded fully and the head sits flush with the finished grade to prevent mowing damage and uneven pop-up height. Verify zone pressure falls within the rated operating range of the nozzle to maintain uniform distribution uniformity.
