Details and features

Chapin 4720 2 Gallon HydroFeed In-Line Fertilizing Injection System for Sprinklers and Direct Hose Use

The Chapin 4720 2-gallon HydroFeed fertilizing injection system is designed for fertilizing with sprinklers and garden hoses. It’s different than a standard hose-end sprayer. It attaches to your outdoor faucet. HydroFeed works differently than a standard hose-end sprayer: it adds water back into the translucent, 2-gallon chemical tank as your chemical is being pulled out. Your chemical sits on the bottom of the tank and is pulled out through the inlet tube as water is being pulled back in. Water stays on top of your chemical mix because it’s less dense than your chemical. It doesn’t dilute the chemical. This is why the water turns clear after your chemical runs out.

The 4720 is ideal for liquid fertilizer and has a filter basket to catch any debris while filling the tank. It has a variable rate adjustment of 1 to 10 ounces per gallon. The drain plug and valve allow you to easily empty the tank after each use. Do not use with drip irrigation systems. Covered by a 1-year limited warranty.
