ABSTRACT OF THE DISCLOSURE A domestic pillar faucet has a main flow path and a control flow path, both connected to the same inlet. A diaphragm supports a valve member for displacement between a position in which the valve member is held open and a position in which the valve member closes the main flow path. Displacement of the diaphragm is controlled by fluid from the control flow path. The control flow path includes an inlet valve and an outlet valve and the section of the control flow path between the valves communicates with the diaphragm. By opening the outlet valve, the force on the diaphragm is reduced and the valve member will open. By closing the outlet valve and opening the inlet valve, the force on the diaphragm is increased and the valve member will close. The valves are operated by a lever through push buttons. The faucet is thus operated in a power assisted manner, not needing the dexterity required when opening or closing conventional faucets.
