Abstract

In an airplane having a pressurized passenger section, with a lavatory sink. The waste water from the lavatory sink is directed either to a toilet tank where it is stored, or to a drain mast line where it is discharged overboard during in-flight operation. A particular fluidic diverting system is used so that when the pressure differential between the passenger compartment and ambient atmosphere is above a certain level, air from the passenger compartment passes through a vent line to cause the fluidic system to operate in a manner that substantially all the waste water is directed through the drain mast line.
