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 fixed 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. The injector contains a check valve to prevent water from flowing into the chemical container while in high pressure mode.
NOTE: Length of hose will determine ability of injector to work properly. It is recommended to keep hose length at 100 feet or less.
