The Chapin HydroFeed fertilizer injector is a patent-pending design filled with features for use with drip irrigation, sprinkler, soaker hose and direct hose spray applications. Great way to conserve water and still have a lush, green, well-fed landscape or garden.
Different than a Hose-end Sprayer
HydroFeed works differently than a standard hose-end sprayer. A standard hose-end sprayer pulls the chemical up and out, emptying the tank. HydroFeed adds water back into the tank as your chemical is being pulled out. Because your chemical has a higher density than water, it sits on the bottom of the tank. Our outlet tube reaches the bottom of the tank so when clean water is being added to the tank, it stays on top of your chemical mix. You don’t have to worry about your chemical being diluted as it’s being fed through the outlet tube. This is why the tank turns clear after your chemical runs out.
