Abstract: Apparatus and methods for distributing and dispensing a potable liquid are claimed. The apparatus comprises a faucet, and a storage tank. A conveying channel is provided for sanitarily conveying potable liquid from an outside source to the tank. The conveying channel includes a sanitary fitting containing an inlet channel. The fitting provides a detachable sanitary connection between the conveying channel and the source. A mechanism for draining free-standing liquid from the inlet channel is also provided. The inlet channel of the fitting terminates at a first coupling which contains an acme sanitary thread. A flow producing mechanism cooperates with the tank and the faucet for causing a flow of liquid from the tank upon the opening of the faucet. A discharge channel is connected to the faucet at one end and connected to receive the flow of liquid at its other end. The discharge channel conveys the flow of potable liquid to the faucet. The source comprises a vehicle with a supply tank mounted thereon.
