The bypass top allows you got choose when this injector is activated or not.


Excellent for Greenhouse Users in the horticulture industry.

The Dosatron® D14MZ2 Injector with a Bypass Top dispenses a wide range of solutions including fertilizers, fungicides, pesticides, disinfectants and algaecides. This injector replaces the popular DI16 Model and allows flow rates up to 14 GPM. Installed directly in the water supply line, it uses water pressure as its power source.

Water activates the Dosatron®, which takes the required concentrate percentage and mixes it with water. The water pressure forces the solution downstream. The dose of concentrate is directly proportional to the volume of water entering the Dosatron®, regardless of variations in flow or pressure in the main line.

This injector is fitted at the top with a functional by-pass, allowing you to choose when it is activated or not.

    this injector seems cheaply made the plastic used for the top bypass valve is thin. also the clamp that attaches the injector body to its mounting unit is very flimsy.
