When peak season heat hits, a failed spray head or a system running at excessive pressure leads to rapid turf stress and significant water waste. With supply chain volatility affecting specialized components, waiting until mid summer to secure pressure regulated heads often results in project delays or settling for non regulated alternatives that fail inspections. Securing your inventory of K-Rain PRO-S series heads now ensures your crew maintains momentum through the spring rush and keeps your installations compliant with evolving local water codes.\u003c\/p\u003e\u003cp\u003eThe PRO-S 40 PSI Pressure Regulated Spray Head offers a distinct advantage over standard pop ups by maintaining a constant nozzle pressure regardless of spikes in the main line. This regulation eliminates wind drift caused by misting and ensures that high efficiency nozzles operate exactly at their design parameters. By choosing this factory set regulated model, you reduce the time your technicians spend troubleshooting coverage issues and eliminate the need for secondary regulators. Investing in professional grade regulation protects your reputation for high quality, water efficient landscapes while reducing long term maintenance callbacks.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHeavy Duty ABS Polymer with Co-Molded Gasket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePop-Up Height\u003c\/td\u003e\n\u003ctd\u003e4 Inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Regulation\u003c\/td\u003e\n\u003ctd\u003eFactory Set 40 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInlet Size\u003c\/td\u003e\n\u003ctd\u003e1\/2 Inch Female NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Diameter\u003c\/td\u003e\n\u003ctd\u003e2 1\/4 Inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCap Color\u003c\/td\u003e\n\u003ctd\u003eBlack with Purple Identification for Reclaimed Compatibility\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Material\u003c\/td\u003e\n\u003ctd\u003eHeavy Duty Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eEPA WaterSense Compliant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe PRO-S Pressure Regulated series is available in 4 inch, 6 inch, and 12 inch pop up heights to accommodate various landscape elevations and plant requirements.

Ensure the head is installed flush with the finished grade to prevent damage from mowing equipment. When installing nozzles, remove the flush plug only after the lateral lines have been cleared of debris. For sites with high debris levels, consider using a swing joint to allow for easy height adjustment and protection against heavy foot traffic.\u003c\/p\u003e","brand":"K-Rain","offers":[{"title":"Default Title","offer_id":52176053764385,"sku":"78004-PR40","price":4.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/78004-PR40_PR.png?v=1766870524","url":"https:\/\/asiwsupply.com\/products\/k-rain-pro-s-40-psi-pressure-regulated-spray-head-4-in-78004-pr40","provider":"ASIW","version":"1.0","type":"link"}
