Downstream injectors are installed after the pump. In order to function, the pressure must be lowered with the use of either a dual lance and soap nozzle, a variable nozzle, a dual nozzle holder, or an adjustable nozzle holder. Water enters the inlet of the injector and creates a venturi which drops the pressure and suctions the chemical from container. Chemical can be injected either in concentrated form or in diluted form. Chemical can be regulated by turning the dial on the injector or installing a metering device on the chemical line. The injector contains a check valve to prevent water from flowing into the chemical container while in high pressure mode.


Refer to the arrow on the injector body for proper flow direction. Install the injector in the system downstream of the regulator unloader which is downstream of the pump. These injectors will draw your chemical into the water stream at 125 PSI and 2.1 to 10.8 GPM, through your low pressure nozzle. Injector WILL NOT draw chemical above 250 PSI through your high pressure nozzle. The amount of chemical drawn in is controlled with the adjustment knob.
