A method of distributing liquid present in the lower portion of a gas pipeline to the interior upper surface of the pipeline including the steps of passing a pig having a venturi therein, through the pipeline, the venturi being actuated by gas pressure taken from within the pipeline, the pig being asymmetrically weighted providing a pig upper portion and a pig lower portion, siphoning liquid from a lower interior portion of the pipeline through the venturi, storing liquid drawn from a lower portion of the pipeline in a reservoir carried by the pig, distributing siphoned liquid from the reservoir onto the pipeline upper interior surface and wherein the gas pressure is taken from a rearward portion of the pig.
