Abstract
Apparatus and methods for converting a bottled water dispenser for use with a continuous source of water are disclosed. In a preferred embodiment, means for reducing the pressure and filtering the continuous source of water are provided. In a most preferred embodiment, the apparatus is configured to substantially reside within the existing dispenser apparatus, thus eliminating the need for bottled water. A housing is provided which contains a filter in an upper portion thereof, the lower portion shaped to conform to an existing tank within the bottled water dispenser in order to provide good thermal communication between the apparatus of the present invention and the existing refrigeration means. Chilled water is retained in the lower portion of the housing and is filtered upon demand, thus providing freshly filtered water to the user at a pressure and velocity substantially the same as that produced using a bottled source, without the contaminants expense and inconvenience associated with bottled water. Also provided are methods and apparatus for converting bottled water dispensers having means for dispensing heated water for use with a continuous source of water.
