The first thing every pressure washer needs is a good water supply. This configuration shows a low pressure quick connector setup to make it easy to connect and disconnect from your water tap You need a garden type hose to get the water to your pressure  washer from your tap.  Some pressure  washers get their water from a water supply other than a tap.  These are usually fixed mounted units on a wash trailer or wash truck.  Others include a myriad of in-plant applications. Your water may not always be clean so it's a good idea to use a water filter before the water gets to the pump The pump is the heart of any pressure wash system.  There are many different kinds of pump.  Axial, plunger, piston are a few.  Need a parts manual or servicing guide for your pressure washer pump?  Click here for links to major pump manufacturers information Pumps can be driven by a number of engines.  Gas, diesel and electric motors are most common but hydraulic motors and power-takeoffs are used for specialized applications  Now that the pump is  making pressure, you need a way to control it.  The unloader valve controls the pressure. It also protects the pump from over pressure  when you close the trigger on the spray gun Everything needs to be put together on a common base,  Depending on the need all can be mounted on a mobile frame, skid frame or wall mounted frame
Now that the water is under pressure you  need to connect a hose to the pumpYou can screw it in to the pump directly but this makes it awkward to remove it, when packing up This configuration shows a quick connect using the common "Euro M22" style connectors.  There are other styles available to make hooking up easier A high pressure hose is needed to carry the pressurized water to whatever devise your using to clean with.  Hoses come in many different styles and lengths, depending on flow rate and pressure.  3/8" is a common size As with the connection to the pump,  you need to connect the hose to a trigger gun or some other cleaning device.   This configuration (left and above photos put together) shows a typical setup that most North American manufacturers use.  It is quicker and easier to use than the Euro M22 style but has an o-ring that occasionally needs to be replaced The spray gun allows the operator to turn the water flow on and off.  The high pressure hose is not always connected to a spray gun if an open system is called for.  ie. continuous cleaning device  A wand provides a way to get the high pressure water to a nozzle.  There are many configurations of wands but the most common is 36" long with a quick connector on the end to accept a nozzle Nozzles are the business end of a pressure washer. This is where the pressureis made.  The size of the hole in the nozzle determines the pressure of the water, based on horsepower of the motor, PSI   and GPM capabilities of the pump
