Abstract: A drain system for adapting the drain/extraction plumbing of a front-loading washing machine which includes an agitator drum mounted for rotation about a generally horizontal axis, means for driving the drum in rotation about the axis during the various cycles of the machine, and a drain pipe extending downward from the agitator drum and disposed to convey a water/suds mixture vacated from the agitator drum away from the drum. The system includes a conduit into which the water/suds mixture is conveyed from the drain pipe. The conduit is oriented generally horizontally with a first end of the conduit intersecting, and being in fluid communication with, the distal end of the drain pipe. The water/suds mixture, as it is channeled through the conduit, separates into a water component and a suds component floating on the water component. The system includes a water scavenger line and a suds duct, both of which diverge and extend from the second end of the conduit.
