We recommend you supply and add a backflow preventer on your water spigot while using the GCI Turf Injection system. Use at your own risk.

A vacuum breaker/backflow preventer prevents contaminated water from entering your home through a water spigot. CLICK HERE to purchase a vacuum breaker/backflow prevention.

The garden hose you use with this injection system should not be used for anything else. 

Three years ago I started telling you about the "Spray Buddy" before. This is the original Spray Buddy. GCI Turf Injection is now what I was calling "Spray Buddy". I changed the product's name because the new name (GCI Turf Injection) fits better. 

The injection fitting itself is an injection molded high-quality poly fitting unique to anything on the market. It is a one-of-a-kind fitting that is not available anywhere else.

GCI Turf Injection allows you to inject select liquid lawn care products into the water flow of any standard garden hose by way of your Flowzone, Strom, or Yard Mastery backpack sprayer. On the business end of your garden hose, you can connect a sprinkler so that your lawn care products are watered in while you are applying them. To manually apply the products please select the Chemlawn Spay Gun option. 

You will need to purchase a 6' short leader hose from your local big box store. The leader hose will connect the injection fitting to your water spigot (A backflow preventer may be added to the water spigot if you choose). Then connect any standard garden hose to the other side of the injection fitting and the other end of the garden hose to your water sprinkler or Chemlawn spray gun. 


GCI Turf Injection is offered in four different ways for the sprayers listed below.

  1. Stainless Steel Fittings
  2. Brass Fittings
  3. Stainless Steel Fittings + Chemlawn Spray Gun
  4. Brass Fittings + Chemlawn Spray Gun

This version of the GCI Turf Injection has a pre-installed 11/16 female poly adapter. This version will connect to any sprayer that has an 11/16 male threaded fitting somewhere in line that the contents of the sprayer exit the tank. This could be an 11/16 male thread on the end of the spray wand, the end of the spray gun, or even on the end of the spray hose where the hose connects to the spray gun. 

We are testing other sprayers not listed for fitment. The following are compatible with sprayers GCI Turf Injection. For connection info see below.
