What is the minimum diameter for a floor sink's waistline?

The minimum diameter for a floor sink's waste line is 2 inches. This specification is important because the larger diameter allows for adequate drainage, helping to prevent clogs and ensure that wastewater flows smoothly away from the sink. A 2-inch diameter also accommodates the volume of flow from sinks, especially in commercial settings where floor sinks might be used in kitchens or food service areas. Ensuring that the waste line is sufficiently sized is crucial for maintaining hygiene and preventing overflow or backflow issues in plumbing systems. A smaller diameter would not effectively handle the waste load, thus leading to potential drainage problems.
