Downstream injection introduces chemical into the system after the pump, so no chemical is ran through the pressure washer pump itself. A downstream injector works by maintaining a certain PSI on the pump side of the injector by means of an orifice installed into the injector body.

The best place to install the downstream injector is to attach quick couplers to both ends and insert it where the pressure hose connects to the power washer. If you are using a hot water power washer then insert the injector where the water exits the burner or the hose reel.

Beside above, how does a chemical injector work? When a chemical or soap nozzle is used, and the pressure is reduced below this point, the ball can lift from the seat inside the injector, and allow chemical to flow. The lower the pressure, the easier it is for the chemical to enter the water stream.

Besides, how is downstream ratio calculated?

Once you have drained the gallon of water out of your chemical mixing tank or with your down stream hose measure the amount of water you ended up with and then divide the amount by 128 (ounces in one gallon) to find out your machines ratio.
