A refrigerator includes a main body, a dispenser configured to supply water to the outside of the main body, a water supply flow path connecting the dispenser to a water source; and a valve assembly disposed on the water supply flow path, wherein the valve assembly comprises an elastic member having an outlet whose diameter is reduced by an elastic force, when water is no longer supplied to the valve assembly, so that water remaining in the inside of the water supply flow path is kept by the surface tension of the water.

A duckbill valve includes a flexible and hollow body having a first shape upon being formed by injection molding. The body in the first shape has a first opening at a first end and a second opening at a second end. The body is configured to be inverted into a second shape. The second shape has a first opening at a first end and has a slit at a second end. The slit is defined by lips that are pressed together to form a seal.

Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float. The moveable float can form a fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and a flow opening when the moveable float is at least partially decoupled from the outlet base. Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.
