The animation video shows how the Mazzei® System works and includes typical installation notes for installing a injection system to water and feed plants.
Mazzei injectors require a sufficient pressure differential between the inlet port and the outlet port to create a vacuum to initiate suction at the suction port.
The drop in water pressure causes a liquid to be pulled into the flow of water.
Where the difference in pressure between the inlet side of the Maxxei injector and the outlet side is small (below 25 – 35%), only a slight vacuum is created. This results in a slight suction being created.
Typical Installations of Fertilizer Injector Systems
A common configuration for controlling differential pressure is when the injector is installed around a pressure-reducing valve. There are several valve options available. The injector may be mounted in the ‘straight’ run or in the bypass portion as shown in the picture
Bypass assemblies should be installed so that the injector outlet is at, or above, the horizontal. ‘Full flow’ valve and pipe fittings should be used so that water flow through the injector is not restricted. When reducing pressure on the downstream side of the injector is not possible, a booster pump can be used to create a sufficient pressure differential to operate the injector.
Proper installation rule: The injector’s outlet must remain flooded. A measurable amount of backpressure must be present for the injector to work properly. Installation of an injector in a vertically down position (outlet below inlet) may cause intermittent or erratic suction by the injector.
Which model of injector should you use?

The Mazzei Injector Selector Tool is for use with Mazzei injectors only. Alternative injector brands do not match the performance of Mazzei injectors for fertilization.
