Chapin 1gal Fertilizer Injector

Chapin’s 4720 2-gallon HydroFeed fertilizer injector works with sprinklers and direct hose spray applications. It’s a great way to conserve water and still have a lush, green, well-fed landscape or garden. HydroFeed works differently than a standard hose-end sprayer: it 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. The 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 fed through the outlet tube. This is why the tank turns clear after your chemical runs out.
