Abstract: A method for retrofitting an aircraft air conditioning unit drainage system comprises the step of removing drain pipe from the unit housing. A hole from which the drain pipe extends is plugged. A first location within a unit housing is determined where during operation of the unit air pressure is lower than at a second location. A second location below the first location is also determined where pooling occurs. A first and a second conduit with first and second internal diameters are respectively located at the first and the second locations. The first conduit and the second conduit are connected to a third conduit which extends generally vertically and which has a third internal diameter that is generally equal to the first internal diameter. A fourth conduit with a fourth internal diameter that is less than the second internal diameter is connected to the third conduit below the second location.
