The 3/4-Gallon EZ-Flo Hose Thread Unit Fertilizer Injector from DripWorks provides an ideal way to fertilize small home gardens. As the name implies, this injector is easy to use. It is also reliable and comes with all the components you need to install it on a standard hose bib. Replacement switching kits (IEZHTRS) are available.
All systems with a fertilizer injector must have a backflow preventer to keep fertilizer from getting back into your domestic water supply. Contact a local building inspector or contractor to determine which backflow preventers are required in your area.
