A valve assembly and a bottom-draining container having the valve assembly. The valve assembly comprising a first body member, a guide member supported by the first body member so that the guide member will extend upward into the container, and a float mounted for movement along the guide member, the float being buoyant in a liquid to be drained from the container, the float having a mating surface for engaging a second mating surface on the valve assembly when the float is in the unsensed position, the mating surface of the float having a configuration for minimizing sticking of the float with respect to the valve assembly.
