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.

The remote dispensing device of claim 5 wherein said flow control valve blocks the flow of water from entering said second outlet passageway in said second state. 7. The remote dispensing device of claim 6 wherein said manifold, hydraulically couples said inlet passageway to said first outlet passageway when said flow control valve is in said second state to define a first recirculation loop for the flow of water between said manifold and the water purification unit. 8. The remote dispensing device of claim 7 wherein said dispensing gun has an outlet coupled normally with said inlet, said manifold includes a third outlet passageway hydraulically coupling said outlet with said first outlet passageway, when said flow control valve is in said first state, to define a second recirculation loop for the stream of water between said manifold and the water purification unit. 9. The remote dispensing device of claim 4 wherein said dispensing gun has an outlet coupled normally with said inlet, said third outlet passageway-hydraulically coupling said outlet with the water purification unit, when said flow control valve is in said first state, to define a circulation loop for the stream of water between said manifold and the water purification unit. 10. The remote dispensing device of claim 3 wherein said flow control valve is a solenoid valve. 11. The remote dispensing device of claim 10 wherein said solenoid valve is selected from the group consisting of flipper-style solenoid valves and rocker-style solenoid valves. 12. The remote dispensing device of claim 3 wherein said electrical component further comprises: a user interface electrically coupled with said flow control valve, said user interface including an electrical control and circuitry operative for switching said flow control valve between a first state in which said flow control valve directs the flow of water to said dispensing gun and a second state in which said flow control valve blocks the flow of water from flowing to said dispensing gun. 13. The remote dispensing device of claim 3 further comprising: a water level sensor coupled electrically with said circuitry and positioned in a container receiving water dispensed from said dispensing gun, said water level sensor operative to generate a signal used to determine a level of water in the container and said circuitry responsive to the electronic signal from said water level sensor for switching said flow control valve from said first state to said second state. 14. The remote dispensing device of claim 3 wherein said flow control valve recirculates the flow of water to the water purification unit when said flow control valve is in said first state. 15. The remote dispensing device of claim 3 wherein said flow control valve recirculates the flow of water to the water purification unit when said flow control valve is in said second state. 16. The remote dispensing device of claim 1 wherein said electrical component comprises: a user interface including an electrical control enabling user input to generate an electrical signal used to regulate the flow of water. 17. The remote dispensing device of claim 16 wherein said user interface further includes a display. 18. The remote dispensing device of claim 16 wherein said electrical component further comprises: a flow control valve configured to hydraulically couple said dispensing gun with the water purification unit, said flow control valve electrically coupled with said user interface. 19. The remote dispensing device of claim 18 wherein said electrical component further comprises: circuitry operative for switching said flow control valve between a first state in which said flow control valve directs the stream of water to said dispensing gun and a second state in which said flow control valve blocks the stream of water from flowing to said dispensing gun. 20. The remote dispensing device of claim 19 wherein said circuitry is operative to energize said flow control valve to provide said first state and to de-energize said flow control valve to provide said second state. 21.
