ABSTRACT:
A control valve system. The system includes a microcontroller electronically connectable to the power supply of an electrical household appliance, such as a washing machine which is connected to the water piping system in a building via hoses. The microcontroller produces first and second electrical signals representing a presence and an absence of electron flow in the power supply. Solenoid valves are responsive to the signals for releasing fluid flow to the hoses responsive to the first electrical signal and blocking the fluid flow responsive to the second electrical signal.
