ABSTRACT:
A reverse osmosis drain coupling and a method of installing it in an existing drain pipe. The drain coupling includes one or more extremities made of flexible, resilient material so that the material can be rolled or folded back upon itself to shorten the coupling. The shortened coupling is inserted between the cut ends of the drain pipe, and the flexible material is then unrolled onto the adjacent cut end or ends to establish a fluid tight relation.
