K-Rain PRO-S Spray Head 4 in. | 78004

Product Overview

A failing spray head during the peak of the summer heat is more than a minor nuisance; it is a direct threat to turf health and client relationships. When budget-grade heads leak or fail to retract, the resulting dry spots and water waste can lead to expensive call-backs and failed site inspections. With peak irrigation season approaching, supply chain delays frequently leave contractors scrambling for reliable inventory. Securing your stock of K-Rain PRO-S spray heads now ensures your crews stay on schedule and your projects remain profitable through the busiest months of the year.

The K-Rain PRO-S series is engineered as a heavy-duty alternative to thin-walled residential heads. It features a co-molded wiper seal that handles high-pressure surges and resists debris better than standard single-piece seals. This durability translates to fewer maintenance visits and a significantly longer service life for your clients. By standardizing your installs with a professional-grade spray head, you reduce labor costs associated with troubleshooting and provide a superior finish that distinguishes your business from cut-rate competitors.

Installation Notes

Before installing the nozzle, ensure the system has been thoroughly flushed to remove any pipe shavings or dirt that could clog the orifice. Thread the spray head onto a standard 1/2 inch swing pipe assembly or rigid riser, hand-tightening only to prevent thread damage. Once the nozzle is installed, use the ratcheting riser feature to align the spray pattern with the turf edge, ensuring the head is installed at grade to prevent damage from landscaping equipment.
