Rainbird National Sls 1804HEVN15 Pop Up Spray Head

Product Description

The RAINBIRD NATIONAL SLS 1804HEVN15 is a Professional Series 4-inch adjustable pop-up spray head designed for residential and commercial irrigation systems. It features a high-efficiency (HE) nozzle that produces larger water droplets at a lower trajectory, reducing system run times by up to 35 percent compared to standard nozzles. The unit ships with a patented pressure-activated co-molded wiper seal that keeps the stem clean and extends service life. A stainless steel retraction spring and stainless steel flow-reduction screw round out the core mechanical components. Inlet size is 1/2 inch. This head is installed by irrigation contractors and landscape professionals as part of zoned spray irrigation layouts.

The 1804HEVN15 is suited for turf and ground cover zones where water conservation and uniform coverage are priorities. The adjustable pattern covers 0 to 360 degrees, making it adaptable to corner, edge, and full-circle applications without stocking multiple fixed-pattern heads. The removable grit filter protects the nozzle orifice from debris in supply lines, which is especially useful during initial system startup or in areas with older piping. This unit is sold in a package quantity of 18, making it practical for contractors stocking multi-zone installs.

Installation Notes

Installation is performed by licensed irrigation contractors or qualified landscape professionals. Shut off the irrigation system water supply and relieve line pressure before removing or installing spray heads. Confirm that operating pressure at the head is within the rated range for the selected nozzle to ensure proper coverage and avoid misting. Follow all applicable local plumbing and irrigation codes during installation and backflow prevention device requirements where required by jurisdiction.
