Downstream chemical injector

We will use a dedicated chemical injector. You may be able to find one at a local store, or you can order a chemical injector from or another online pressure washing supply store. The chemical injector has tube which is placed in a bucket of mixed detergent, and draws the chemical into the pressure washer hoses when a soap nozzle is attached to the trigger gun. Then by switching to a higher pressure tip, the soap can be emptied out of the lines so it is possible to rinse with water. When Soft Washing with the 8 GPM Pressure Pro we will not be using the chemical injectors feature of turning off with higher pressure tips. Instead we will move the detergent line to water to rinse or install a 1/4 shutoff valve to turn off the detergent while we rinse with less than 100 PSI nozzles.
