All systems with a fertilizer injector must have some sort of back flow preventer to prevent fertilizer from getting back into your domestic water supply.
 

Mazzei (Venturi type)

The Mazzei is a commercial grade injector with no moving parts. One of its chief advantages is that it works by suction and will draw liquid fertilizer out of almost any container you provide. The Mazzei can be plumbed on a bypass for less restriction ( the preferred method), or directly into a main water line. It is important to choose the model size carefully; too large and the unit will not draw the fertilizer at all, too small and you will restrict the flow of the system. If in doubt always choose a smaller size and put it on a bypass assembly. This allows you to adjust the flow through the Mazzei and does not restrict the flow as much. Remember, this is not as exacting as the Dosmatic. You will need to experiment to get the dosages required but once operating, the Mazzei is incredibly reliable and easy to use. All sizes have Male Pipe threads on the inlet and outlet, which are easily adapted to hose threads.
