Abstract: The embodiments described herein include an apparatus for adapting an existing water fountain having a water supply line and an existing bubbler assembly for dispensing water to a filtered water fountain. The system includes an adapter base in fluid communication with the water supply line, a housing assembly secured to the adapter base, and a bubbler head assembly secured to the housing assembly for dispensing water. A filter cartridge assembly is disposed within the housing assembly and is in fluid communication with the adapter base and the bubbler head assembly.

Abstract: A protective cover is provided for substantially enclosing and protecting a bubbler head of a drinking fountain or the like against contamination when water flow to the bubbler head is turned off. In one preferred form, when the water flow is turned on, the protective cover is hydraulically elevated or pops up to a raised position permitting substantially unimpeded projection of a water stream from the bubbler head for drinking, etc. In an alternative preferred form, the bubbler head is hydraulically elevated or pops to a raised position within a stationary protective cover when the water supply is turned on for substantially unimpeded projection of water stream from the bubbler head through an open flow port formed in the cover.

Abstract: A pop-up bubbler assembly for drinking fountains or other appliances that includes a head with a dispensing spout that rises upward out of a housing to dispense an arc of clean water when activated. The bubbler head then drops back down into the housing after water flow stops such that the dispensing spout is covered when not in use.

Abstract: A bubbler includes a plastic valve body having a cavity for receiving an internally threaded metal mounting base and a pocket for receiving a flow regulator. Screws are threaded into holes in the valve body for holding a metal mounting base and a flow regulator in the cavity and pocket. A plastic shield is mounted to the valve body with a snap fit.

Abstract: A drinking fountain which is adjustable in height to accommodate persons of different heights and persons confined to wheelchairs, thereby obviating the need for providing two separate drinking fountains of different heights.
