  • Unloader valve. The unloader valve opens to relieve water pressure and recirculate water through the pump when the spray wand isn’t in use and the pressure washer is running. Recirculating water helps prevent the pump from overheating when the spray wand isn’t discharging water.
  • Spray tip. The spray tip connects to the end of the spray wand. The spray tip restricts water flow and creates a spray pattern. An assortment of spray tips is usually provided with the pressure washer.
  • Water pump. The water pump is connected to the motor drive shaft. The motor drive shaft spins the pressure washer pump to create the water pressure for the spray nozzle.
  • Pressure hose. The pressure hose connects the pump to the spray wand. The pressure hose carries the pressurized water safely from the pump to the spray wand.
