Under-sink tie-in made simple: this ABS dishwasher wye solvent-welds to 1-1/2″ ABS DWV at the central and branch hubs, then accepts a 1/2″ barbed dishwasher drain hose for a secure connection (use an appropriate clamp). Built for non-pressurized DWV service and aligned to ASTM D2661 and CSA B181.1; ABS DWV systems are commonly cUPC/NSF-14 listed. Follow local code—many jurisdictions require a high loop or air gap on dishwasher drains.
