Dishwasher Drain, Clean Tie-In
ABS dishwasher wye for tying a dishwasher drain hose into the sink waste line under the counter — the compact fitting that solvent-welds into a 1½" ABS DWV run and presents a ½" barbed outlet for the appliance hose. The two hub ends bond to ABS pipe; the barb grips the flexible drain hose and holds it with a clamp. It's built for non-pressurized DWV service and meets ASTM D2661 and CSA B181.1, with the cUPC and NSF/ANSI 14 listings an inspector checks across the GTA. Many jurisdictions require a high loop or air gap on a dishwasher drain — most appliance makers specify roughly a 32" high loop where no air gap is used, so check local code before final connection. A clean, code-friendly way to branch a dishwasher into the sink drain without cutting in a separate tee and adapter.
