3/4" Mazzei Injectors and Accessories

Built for the tough demands of commercial fertilizer liquid irrigation, the Mazzei injector boasts commercial-grade dependability and performance. These Mazzei venturi-style injectors have no moving parts to wear out or break. Working by suction, the Mazzei can draw water from practically any container.

You can plumb a Mazzei injector on a bypass. After a little experimenting to get the right dosages, you will enjoy reliable service that is relatively maintenance-free. Rebuild kits are available for all Mazzei injectors, meaning you can make them go the extra mile for you.

An injector, bypass and suction assembly are required to make a complete unit. These items are sold separately.

Before you buy, make sure to choose the right size based on your irrigation system's water usage. Pick an injector that matches your flow rate (GPH). An oversized injector will not draw any fertilizer at all, and an undersized one will restrict the system.
