The
high pressure nozzle is a very important part in your power washer. The
wash nozzle eventually wears down and will need replacement with a constant flow of pressurized water. The washing
spray nozzle is actually the part that creates the pressure. The amount of pressure you will get is controlled by the size of the orifice of the
windshield washer nozzle. The bigger the orifice and the lower pressure you will get.
