Disclosed is a water dispensing system for an aircraft wherein hot and cold water supplied to a faucet disposed above a washbasin in a controlled manner including solenoid valves for both the hot and cold water. Two manually operated switches are employed to energize, respectively, the hot and cold solenoid valves. Two different timing cycles are employed. In one timing cycle, when one switch is actuated and then the other switch is actuated within a predetermined time period, both solenoid valves will be turned on to provide approximately equal volumes of water to the faucet for a predetermined time period. In another timing cycle, when one switch is actuated and the other switch is actuated within a predetermined time period, the solenoid valve means energized by the first switch will be turned off and the second solenoid valve will be turned on for a predetermined time period.

A water dispensing system for an aircraft comprising: a water supply including a source of hot water and a source of cold water, vent means in communication with the water supply which closes upon the water supply being filled with water to allow the water to be pressurized and, when the aircraft is on the ground and being drained, vents the water supply to atmosphere, a washbasin and faucet combination, said faucet being disposed above the washbasin, conduit means between the faucet and water supply including a common channel which at one end is in communication with the faucet and at the other end is in communication with the source of hot water and the source of cold water, manually operable switch means for controlling the delivery of water from said water supply to the faucet, said switch means including a first switch controlling the operation of a first solenoid valve means for turning on the flow of hot water and a second switch controlling the operation of the second solenoid valve means for turning on the flow of cold water, said first and second solenoid valve means being coupled to timing control means for selectively controlling the timing cycle during which said first and second solenoid valve means are energized, the timing control means including means which, when one switch is actuated to energize one of the solenoid valve means and the other switch is also actuated during a predetermined period, resets the timing cycle so that both solenoid valve means are energized for the same length of time, and in said dispensing system, the water flowing from the faucet comprises approximately equal volumes of water from said source of hot water and said source of cold water.
