  • Water leakage protector apparatus
    Patent number: 5992218
    Abstract: A water leakage protector apparatus for appliances subject to leakage includes a first device for detecting water leakage from the water supply line coupled to the appliance and a second device for detecting water leaking from the appliance itself. A control apparatus is coupled to a valve, affixed to the water supply line, is connected to a source of electrical power, and controls the water flowing to the appliance. The appliance is connected to the control apparatus to obtain electrical power for operation. The first and second sensing devices are coupled to the control apparatus so that when a water leak is detected by either the first or the second detecting device the control apparatus stops the water from flowing in the water supply line and interrupts electrical power to the appliance.
