ABSTRACT:
A household under-counter reverse osmosis (R/O) water filtration installation wherein the R/O reject waste water under-counter drain line is coupled into a sink drain trap in parallel drainage relation with a garbage disposer sink by a baffle Tee plumbing fitting having first and second normally open inlets perpendicular to one another. The garbage disposer outlet is coupled by a standard slip fit single inlet/outlet fitting to the baffle Tee first inlet. The baffle tee has a single outlet slip coupled to the inlet of the trap. An R/O drain adapter elbow of the invention has its inlet connected to the waste water drain line tube and its outlet coupled to the Tee second inlet. The adapter provides an end closure structure which, with the elbow, sealably closes the second inlet of the Tee. In one form the adapter end closure structure is directly attached to the baffle Tee second inlet and comprises a circular wall with a through-opening including the elbow outlet, a standard ring seal or washer seated on the baffle Tee second inlet and a slip joint nut threadably received on the baffle Tee second inlet and clamping the closure wall periphery and washer sealably together. In another form a series of S/J standard plumbing fittings may connect a non-disposer sink drain outlet of a single sink installation directly to the trap. A three-way Tee has its coaxial inlet and outlet ends serially slip coupled into these fittings and the R/O drain adapter end closure structure and associated elbow outlet are attached to a side T-inlet of the three-way Tee.
