摘要:
A draining device for use with a fluid spout includes a main body including a stem portion defining a first aperture configured to fluidly couple with a pressure source. The main body may further define a base portion defining a second aperture configured to fluidly couple with a fluid spout of the fluid spout. The main body may further define an internal passage extending from the first aperture to the second aperture. The main body may fluidly couple the pressure source and the fluid spout through the passage.
