The floor sink drain for the Wendy's restaurant requires what size sanitary line?

The appropriate size for the sanitary line connected to a floor sink drain in a commercial establishment like a Wendy's restaurant is typically 3 inches in diameter. This size is suitable to accommodate the high flow rates and the potential volume of wastewater generated from kitchen activities, such as dishwashing and food preparation, which creates a considerable amount of drainage.

Using a 3-inch line helps ensure that there is adequate capacity for draining water efficiently without causing backups. Proper drainage is critical in commercial kitchens, as it prevents health code violations and maintains a clean and functioning environment. Smaller pipes may lead to clogs and inefficient drainage, while larger pipes can be unnecessary and not cost-effective for this application. Thus, a 3-inch diameter line is the standard choice for floor sinks in a restaurant setting.
