A replaceable flow assembly for use in a water cooler or similar bottled liquid dispenser includes a liquid reservoir 7 and a manifold 48 incorporating a bottle connector 5, 49 for releasable sealing engagement with a neck formed on an inverted bottle. The manifold is mounted on the reservoir and incorporates a first pathway for conducting liquid from a feed tube 5 to the reservoir 7, and a second pathway for conducting liquid from the reservoir to a discharge outlet 53. A third pathway within the manifold conducts atmospheric air through an air filter 28 and into the interior of the bottle through the feed tube 5 without passing through the reservoir 7. The manifold preferably also incorporates a dispense valve between the reservoir 7 and the discharge outlet 53 (e.g. in arm 52), which co-operates with a fixed valve-operating member within the dispenser.

A bottled liquid dispenser according to claim 1 in which the manifold comprises an upper moulded shell and a lower moulded shell which are sealably joined together. 3. A bottled liquid dispenser according to claim 1 in which the third pathway includes an air filter which is mounted within the manifold. 4. A bottled liquid dispenser according to claim 1 in which the third pathway includes a non-return valve which is mounted within the manifold. 5. A bottled liquid dispenser according, to claim 1 in which the manifold provides a fourth pathway for conducting liquid from the first pathway to a further discharge outlet without passing through the reservoir. 6. A bottled liquid dispenser according to claim 1 in which the second pathway travels through a post which is upstanding from the manifold alongside the bottle connector. 7. A bottled liquid dispenser according to claim 6 in which an arm projects from the upper end of the post away from the bottle connector, and the second pathway travels through the arm. 8. A bottled liquid dispenser according to claim 7 in which the arm carries said discharge outlet through which liquid is dispensed after passing through said second pathway. 9. A bottled liquid dispenser according to claim 1 in which-the housing has a removable apertured lid for supporting an inverted bottle with its neck projecting therethrough, said lid overlying the receiver cup of said bottle connector. 10. A bottled liquid dispenser according to claim 9 in which the lid holds the manifold between the lid and the support structure of the housing.
