How does a pressure washer work?

Water source: The pressure washer is connected to a water source like a garden hose.

Backflow device: prevents water from siphoning from the pressure washer to the water source.

Filter: The filter eliminates contaminants from the water that could damage the pump.

Internal water tank: Some pressure washers have an inner water tank that can be used if a water source is unavailable.

Water flow from the tank: If the pressure washer has an internal water tank, the water flows from the tank to the pump.

Direct water flow: If the pressure washer is connected to a water source, the water flows directly to the pump.

Detergent tank: Some pressure washers have a detergent tank that can add soap or other cleaning chemicals to the water.

Low-pressure detergent flow: The detergent is drawn from the tank at low pressure.

High-pressure detergent flow: The detergent is mixed with the high-pressure water before it exits the nozzle.

Pump: The pump increases the pressure of the water.

Motor: The motor powers the pump.

Bypass valve: The bypass valve allows some of the water to bypass the pump, which helps to prevent the pump from overheating.

High-pressure flow hose: The high-pressure water exits the pump and flows through the high-pressure hose.

Lance: The lance is a long, thin tube that connects the high-pressure hose to the nozzle.
