The EZ Flo 1010-HB Garden Hose Fertilizer Injector w/ Backflow Preventer installs on your outdoor water faucet / tap and connects to a garden hose to accurately feed your flowers, trees, or shrubs with water-soluble or liquid fertilizers. This fertilizer injection system is used by professionals in garden centers and greenhouses, as well as home gardeners who want to maintain a healthy garden and beautiful landscape. The Ez-Flo system can be used with any water-soluble or liquid fertilizer, connects at the faucet, and feeds through a garden hose, watering gun, watering nozzle, sprinkler, drip irrigation system, or deep root waterer. It provides you with a quick and easy way to accurately feed flowers, trees, or shrubs without having to constantly refill the tank and can be moved around the garden to feed multiple areas. Installing EZ-Flo is like having a full-time gardener fertilizer your property each time you water. It feeds in small amounts each time you water, which allows plants to develop healthier roots and makes them less vulnerable to disease.

The feeding rate can be adjusted using the dial on the top of the lid. One fill up should typically feed 7000 square feet of turfgrass or 9500 square feet of mixed landscape. At this rate, you should be refilling the unit every 4-6 weeks.

Easy to install and easy to use: Refill the tank with a non-hazardous liquid or water-soluble fertilizer once the unit is empty. The cap does all the mixing and proportioning of fertilizer by automatically sensing and adjusting to changes in pressure and flow. Can be adjusted to various dilution rates.

Backflow Preventer: Backflow preventers are required when using any fertigation system. For EZ Flow units attached to a water faucet, the minimum backflow preventer is an anti-siphon valve upstream from the hose bib connection point. Backflow preventers are used to protect potable water supplies from pollution and contamination due to backflow.
