A valved stem apparatus for use on a water pipe used for smoking. The valved stem is formed as an elongated hollow stem provided with a first open end, sized for mechanically interfacing with a pipe bowl assembly component of the water pipe, and with a second open end for being disposed within a liquid container member of the water pipe. The second open end is provided with a retaining structure that extends from the stem structure that delineates an opening at the second open end. A valve member, such as a ball valve, is disposed within the retaining structure such that it can freely travel within the retaining structure towards the opening portion of the second open end upon being submerged in a liquid. The opening portion is formed with a smooth beveled rim surface that conforms to the shape of the outer surface of the buoyant body to effect closure of the opening in a water-tight manner when not being forced open by a person drawing smoke from the mouthpiece. Once the drawing of smoke ceases, the buoyant force takes over to reclose the opening. The interior of the stem is essentially kept void of the liquid since the re-closure is virtually instantaneous. Any inadvertent tipping of the water pipe apparatus will not cause the buoyant body to be moved away from the opening of the hollow stem member and thus prevent any spillage of the liquid via the stem supporting the pipe bowl.
