Abstract
A fresh water supply system for an aircraft has at least one supply tank connected to one or more water taps or faucets through a main line, including a device for conveying the water, for example by a pump, by suction, by pressure, or even by gravity. An auxiliary tank or reservoir is arranged near a tap or faucet, and the auxiliary tank is connected to the main line by a controllable valve. The conveying device is connected with a control, which operates in such a way that the main line is filled with water only during first time durations while it is filled with air during second time durations. A venting valve is connected to the main line to permit the venting of the main line when water is removed from the main line. Air also escapes through the venting valve when the main line is being refilled with water.
