  • Built-in check valve: Prevents low-head drainage and eliminates small leaks at lower elevations.
  • Reduces misting and overspray: Pressure regulation reduces fogging, wind drift, and wasted water at the nozzle.
  • Retro-fit design: Drop-in component fits nearly all existing pop-up sprinkler stems and installs in minutes.
  • Easy installation: No special tools required for insertion; set pressure, drop in, and replace nozzle or cap.
  • Compatible with popular brands: Designed to work with many common spray bodies including Rain Bird, Hunter, Orbit, Weathermatic and others.

Ideal for homeowners and landscape professionals who want a low-cost, low-waste solution to convert older spray heads to more efficient outlets. The HW-1800 helps reduce water use, limits misting and overspray, and simplifies maintenance by using existing sprinkler hardware.
