Reasons for Well Pump Pressure Switch Failure



The pressure switch comprises a simple internal spring mechanism connected to a set of electrical contacts. Over time, the spring weakens, parts clog with debris, and the electrical contacts corrode and degrade.

Why is my pressure tank short cycling?





Loss of air charge inside your water tank is the most common cause of short cycling. It is an especially common problem for older models and non-bladder type (also called captive air tanks) water pressure tanks. Newer bladder type tanks can also develop this problem when the bladder is damaged.
