A water dispensing device for dispensing water at a location remote from a water purification unit and methods of using the water dispensing device and methods of operating such remote water dispensing devices. The water dispensing device includes a dispensing gun, a support structure for the dispensing gun, and a manifold hydraulically coupling the water purification unit with the dispensing gun for supplying a stream of water from the water purification unit to the dispensing gun. The water dispensing device is also equipped with a flow control valve operative for selectively directing the stream of water from the manifold to the dispensing gun. Equipping the remote water dispensing device with a manifold and flow regulation device permits the flow of water to be regulated locally at the water dispensing device, in contrast to regulation only at the water purification unit.
