Pressure Washer Flow Switches

Flow switches detect the flow of water in your system. When water movement is detected, the switch opens or closes the circuit to trigger other elements in your machine. These switches are important to protect your pressure washer equipment from damage, especially in hot water systems, where unregulated burner operation can result in dangerous pressure buildup and excess fuel consumption.
