The Pro Products P1X GreenFeeder is a water-driven automatic injection system that delivers measured fertilizer and pest-control concentrates through an existing irrigation system. Designed for residential and light-commercial landscapes, the GreenFeeder adjusts feed rate based on water flow so you get consistent application without electricity or timed programming.

  • AUTOMATIC INJECTION: Feeds every time the irrigation runs; no electricity required.
  • WIDE FLOW RANGE: Operates from 0.5 to 40 GPM and 25–125 PSI for versatile systems.
  • EASY INSTALLATION: Installs above or below ground after the backflow preventer; can be mounted vertically, horizontally, or at an angle.
  • STANDARD CONNECTION: 1" inlet that can be adapted down to 3/4" (adapters not included).
  • COMPATIBILITY: Use with GrassSoGreen, NatureShield, or Rid‑O’Rust products when iron is under 2 ppm.
  • BOX CONTENTS: GreenFeeder unit, quick-connect hose, flow directors, and installation guide.

Ideal for smaller lawns and city-water applications, the P1X makes routine fertilization and targeted pest control simple and reliable. Refer to the owner’s manual for installation diagrams, winterization steps, and routine maintenance to extend service life.
