An apparatus for converting a conventional bottle-water cooler into a self-filling bottles water cooler is provided. The apparatus includes a water bottle, a water inlet system, a venting system and a seal. In one embodiment, the seal is flat with a central opening which is stretched over the neck of the bottle and released, which allows the disk to assume a cylindrical configuration in engagement with the outer surface of the neck. The neck with the seal is then fimly pressed inside the water tank. In another embodiment, the seal includes rounded ridges disposed concentrically on one side of the seal with the ridges being successively wider and thicker towards the outermost edge of the seal.
