Effortless Hose-End Fertilizing for Home Gardens & Lawns

The Chapin HydroFeed Fertilizer Injector connects inline between your outdoor faucet and your garden hose so fertilizing happens automatically while you water — no extra steps. Available in 16 oz (Model 4700), 24 oz (Model 4701), and 32 oz (Model 4702) sizes. Compatible with liquid fertilizers, granular concentrates, and fish emulsion. Works best at 40 PSI; maximum incoming pressure 60 PSI. Mixes at 1 oz concentrate per gallon of water. Backed by a 1-year limited warranty.

Important: This injector is not compatible with drip irrigation systems. It is designed for use with standard garden hoses and sprinklers only. For drip system fertigation, see our drip-compatible fertilizer injectors.

Frequently Asked Questions

Can I use this with my drip irrigation system?
No. The HydroFeed is not compatible with drip irrigation systems — it is designed for garden hoses and sprinklers only.

For drip system fertigation, browse our drip-compatible fertilizer injectors, including EZ-FLO, Mazzei, and MixRite models.

What pressure does it require?
Works best at 40 PSI with a maximum incoming pressure of 60 PSI.

If your home water pressure exceeds 60 PSI, install a pressure regulator upstream to protect the unit.

Do I need a backflow preventer?
Yes — a backflow prevention device is strongly recommended whenever fertilizers are injected into a residential water supply.

Browse our backflow prevention devices to find a compatible option.
