Hot water pressure washers are designed to do two things: heat water and pressurize it. But hot, pressurized water can present a danger. How do you keep your employees – and your equipment – safe? Read on:

The pressure switch is a standard safety feature on most industrial hot water pressure washers. It works like this:

• The operator pulls the trigger on a pressure washer gun.
• Pressurized water begins to flow through the system.
• The pressure switch activates, signaling the burner system to fire and heat the water.
• When the trigger is released, the pressure switch deactivates and the burner system shuts off.
• Pressure switches are small but important mechanisms that keep your employees safe from accidentally discharging hot, pressurized water.  They also help prevent the burner system from overheating, resulting in costly repairs.
