What is the standard kitchen sink drain configuration?

The kitchen sink drain in Quebec must comply with Plumbing Code rules:

Configuration:

• Drain diameter: 1 ½ in (38 mm) minimum for a standard sink
• A double basin sink: both drains connect via a T-fitting, with a single P-trap downstream
• Maximum distance between the trap and the drain T: 300 mm (12 in)
• Pipe bends: no tight 90° elbows — use two 45° elbows or a sweep elbow

Accessories:

• Garbage disposal: The disposal connects directly to the sink drain (main basin side). Disposal outlet: standard 1 ½ in
• Dishwasher: The dishwasher drain connects to the sink drain before the trap, via a rubber fitting. A high loop is required — hose secured under the counter at least 750 mm from the floor

Materials: Sink drain pipes are typically black ABS (most common in Quebec), white PVC, or stainless steel for designer sinks. ABS is preferred for its durability and ease of installation.
