The Rheem/Ruud 42-106257-01 Negative Pressure Switch is an essential component for maintaining the proper functioning of your heating system. This switch is designed to protect your heating appliance from damage caused by low water pressure in the system.
The switch is equipped with a diaphragm that senses the pressure changes in the water line. When the water pressure drops below the set limit, the diaphragm moves and closes an electrical contact, which in turn triggers an alarm or shuts off the heating system to prevent any potential harm. This ensures that your heating system is only operational under safe and optimal conditions.
