<p>An integral, vacuum operated, package system for collecting and transporting waste liquids from, e.g., a defrosted freezer, sink, bathtub, or water fountain, to a vacuum transport conduit connected to a vacuum collection station. The package system preferably includes a collection sump, sensor valve, controller valve, vacuum volume, and vacuum valve, which operatively communicate with each other by means of applied differential pressure to withdraw waste liquid from the collection sump and pass it through an opened vacuum valve during a transport cycle. The package system is compact, portable, and easily installed and maintained, and may be concealed in most applications, since it requires a mere volume generally measuring 12''x8''x31/2.</p> |
