Guide to Pressure Washer Chemical Injectors & Foamers

Chemical is injected into the out-put line (between the pump and lance)

The way it works is you change the NOZZLE to a "Low Pressure Nozzle"
Open the control metering valve on the injector
Then when you pull the trigger on the gun the water flow picks up chemical.
To adjust the flow of chemical you either turn the metering knob on the injector or use a "stand alone" metering valve - (this is sometimes better for fine control)
A PVC tube drops into you chemical can with a fliter on the end.

Match the flow of your pump to the right Injector

Always have the INJECTOR on the input side of the last length of high pressure hose.

The other way to do it if you require HIGH PRESSURE & CHEMICAL is to use a "DEMA" Constant Pressure Injector. - click here
