A.O. Smith 9006017015 Pressure Switch

The A.O. Smith 9006017015 Pressure Switch is an essential part of HVAC systems as its primary function it control the water pressure in the system. It works with the help of a switch that measures changes in water flow and either turns on or off the system’s pump. Depending on the defined pressure the switch alerts the pump to supply enough water flow to maintain proper system functionality and avoid further deterioration. On the other hand, when the pressure increases beyond this point, the switch tells the pump to stop pumping to avoid high pressure and possible leakage.
