Do all pressure washers have a soap dispenser?

    are you asking if it is possible to use the little 4hp power washer to inject soap into a bigger power washer?

    look for a dema valve, it is used in the car wash industry to mix a small about of soap into water, based on the flow of the water, it is adjustable.

    you put it in line with the water coming in and then the suction of the water going by pulls the soap(or whatever) into the stream at an adjustable amount.

    Hanna is a car wash manufacture that sells them

    Good luck.
