Key Features
This double kitchen sink plumbing layout includes:
- Strainers and strainer tailpieces on both bowls
- Dishwasher connection tailpiece on the left bowl
- Dishwasher drain hose with a high loop under the counter
- Continuous waste horizontal pipe between the bowls
- P-trap below the right bowl
- Sani-tee tying the trap arm into the drain and vent
- Two 45-degree elbows on the drain line
The dishwasher hose rises to the underside of the countertop before it drops to the tailpiece, which keeps dirty sink water from backing up into the dishwasher.
Key Considerations When Installing a Double Kitchen Sink
Both bowls and the dishwasher share a single trap, so the continuous waste pipe needs enough fall to carry water over from the far bowl. ArcSite lets you draw this layout to your customer's cabinet width, so you know the trap and tee fit before you cut any pipe.
