How do you get the gas pressure washer to pick up bleach?

If your washer came with the standard siphon hose (most do), the virtual "on-off" switch is the black spray tip with the large orifice..or for the washers without individual tips..just the vari-nozzle on the end of the wand...then you must push the nozzle housing outward to the low pressure position. Chemical injectors typically only work in the low pressure mode. The low pressure mode is engaged when the black (large hole in center) nozzle is used. Simply lower your siphon hose into soap concentrate. It will automatically be diluted 10x when sucked out by the water rushing through the pump outlet.
