A battery-powered, sensor-operated flush valve for controlling water flow through a toilet room device such as a urinal or water closet includes a flush valve body with an inlet and an outlet. There is a valve mechanism for controlling flow through the flush valve body. A solenoid is attached to the flush valve body and has a piston which is positioned to contact the valve mechanism relief valve. The solenoid is in circuit with a battery and a sensor whereby a user of toilet room device will cause battery power to be applied to the solenoid coil, which will in turn move the piston to contact the relief valve to institute a flushing operation.

A soap dispenser includes a soap supply, a motor driven pump connected by tubing to the soap supply and a soap output device connected by tubing to the motor driven pump. The electric drive circuit for operating the pump motor includes a sensor for detecting a user's hands positioned to receive soap from the output device. There is a forward motor control circuit connected to the sensor and to the pump motor and responsive to a start signal from the sensor to drive the pump motor in a forward direction to supply soap to the output device. There is a volume adjust circuit connected to the forward motor control circuit and to the sensor to provide a stop signal to the forward motor control circuit a predetermined time period after receipt of a start signal from the sensor. There is a reverse motor control circuit connected to the pump motor and to the volume adjust circuit and responsive to a stop signal from the volume adjust circuit to drive the pump motor in a reverse direction to reverse the flow of soap to the output device.
