Low Water Pressure Switch Problems
1.Pressure Switch Springs
-
Pressure switches consist of two basic parts: a set of pressure adjustment springs and a set of electrical contacts. The two pressure adjusting springs operate in concert to both turn the water pump on and turn it off. The larger of the nut-adjustable springs controls the overall pressure range of the on-and-off operation. Typically the spring is factory-set to turn the pump on at 30 pounds per square inch (PSI) and turn the pump off at 50 PSI. Turning the nut in a clockwise direction raises the range. The smaller spring nut adjusts the overall pump off pressure. By turning the nut in a clockwise direction the off pressure will be raised. If the smaller adjustment spring and nut combination is turned too far in a counterclockwise direction, the pump will never shut off and the pump may fail due to overuse. These pressure springs are mechanically attached to operate the electrical contacts.
