What is the minimum diameter required for waste opening Inlet for food grinders?

  1. 2 inches

  2. 2 1/2 inches

  3. 3 inches

  4. 3 1/2 inches

The correct answer is: 3 1/2 inches

The minimum diameter required for the waste opening inlet for food grinders is 3 1/2 inches. This size is specified in the Illinois Plumbing Code to ensure that food waste can be effectively and efficiently transported through the plumbing system without causing blockages. A larger diameter provides better flow rates and reduces the likelihood of clogs, which can occur if waste is improperly handled. This specification is particularly important in commercial kitchens where food grinders are frequently used, as they tend to produce large volumes of waste that need to be disposed of quickly and safely. Smaller diameters might not accommodate the volume or texture of waste produced by food grinders, leading to potential plumbing issues. Therefore, adherence to the 3 1/2 inch requirement promotes better system performance and longevity of the plumbing infrastructure.
