An adapter for coupling a corrugated drainpipe to recreational vehicle discharge pipe employs a tubular member having a discharge pipe end portion of a shape and size adapted to be placed over an outlet end of the discharge pipe, and a drainpipe end portion having a shape and size adapted to engage threadably an end of a corrugated drainpipe. A helically-shaped thread along the drainpipe end portion are sized and shaped complementary to conform to the corrugations of the corrugated drainpipe enables threaded engagement of the corrugated drainpipe.
