RO Drain to Disposal Kit

The RO Drain to Disposal Kit (DLA-D38QC) from Air Gap provides a clean, code-compliant way to connect a reverse osmosis system's drain line and a dishwasher to a garbage disposal. It features a 3/8-inch quick-connect for RO poly tubing and a 7/8-inch outlet that fits all standard garbage disposal inlets, so you can route reject water away neatly while leaving your existing plumbing intact. The result is a tidy under-sink installation that avoids cutting into or rerouting drain pipes.

Simple, Quiet, and Certified

The universal inlet offers multiple barb connections sized to accommodate 1/2, 5/8, 3/4, and 7/8-inch inside-diameter dishwasher hoses, and the durable plastic barb can be trimmed to fit the hose you have. Engineered to eliminate the gurgling and reject-water noise common to RO drains, it also includes a self-cleaning port for trouble-free operation over the long term. If the RO port is not needed, it can simply be plugged with a 3/8-inch plastic dowel, making the adapter equally useful for dishwasher-only installations.
