A handless or footless operation of an electrical automatic water flow control apparatus for turning water on and off without touching the faucet lever of a faucet. The electrical water flow control apparatus is installed in line between the water shutoff valves from the wall and the water supply lines that descend from a faucet. The flow control apparatus includes a housing which houses a pair of solenoid operated valves. Each solenoid operated valve has an inlet port and an outlet port, where the ports are protruding through a wall of the housing. The inlet ports are connected to the hot and cold water shutoff valves by flexible hoses. The outlet ports are connected to the water supply lines from the faucet by flexible hoses. The electrical flow control apparatus further comprises an elongated bar switch actuator and a transformer which supplies power to the solenoid operated valves. The bar switch actuator is constructed of micro-switches which are electrically connected together and to the solenoid operated valves. The solenoid operated valves are operated by depressing any part of the elongated bar switch actuator with any part of body of a user, which when depressed energizes the solenoid operated valves to open to allow the flow of water therethrough and when the elongated bar switch actuator is not depressed, closes the solenoid operated valves to stop the flow of water through the flow control apparatus.
