Treated water dispensing system

A water dispenser including a housing having a water treatment tank, a water inlet selectively feeding water into an upper section of said tank, cooling coils acting to chill water in a lower section of said tank, an ultra-violet lamp disposed in both the upper and lower sections of the tank for transmitting ultra-violet light rays to water in both upper and lower sections to eliminate bacterial growth in both upper and lower sections, a first faucet communicating with said lower section for dispensing chilled water selectively, a second faucet, and a supply conduit communicating water in said upper section with said second faucet for dispensing water which has not been chilled selectively, a first probe, and a controller, said first probe communicating a low water level signal to said controller to activate the lamp and then direct water to enter the tank from the water inlet, said controller utilizing a timer to determine whether a refill time exceeds a predetermined expected refill time, and if said refill time exceeds the predetermined expected refill time, said controller sending a signal to secure the water inlet.

• said controller is connected to a solenoid controlled valve in communication with the water inlet valve and said controller activates the lamp prior to opening the water inlet valve, and said lamp is allowed to achieve a desired operating temperature before the controller opens the water inlet valve.
