0 Paul Kassander 26 Report post Posted January 18, 2011 Down steam injection is where an injector is placed downstream of the pump and unloader (after pump). If you have a hot water unit it is placed after the heater. When the pressure on the line is dropped that causes the back pressure to be reduced within the injector. When the water flows through the injector nozzle it shoots across an internal chamber in the injector and creates an area of low pressure or vacuum (VENTURI). This allows the soap to be sucked up through the chemical line and mix with the water headed to the gun. When the pressure wash line is put back to a high pressure mode it creates back pressure in the line which fills the chamber and forces a check ball to be seated in the barb that prevents water from flowing back to the chemical tank.
