How large should the waste line for commercial type food grinders be in Illinois Plumbing Code practice?

1 inch
1 1/2 inches
2 inches
2 1/2 inches

The correct answer is: 2 inches

In Illinois Plumbing Code practice, the correct size for the waste line serving commercial type food grinders is indeed 2 inches. This specification is based on the need to accommodate the volume and nature of waste being processed by such equipment, which can produce a significant amount of food waste and require efficient drainage to prevent clogs and backups. Commercial food grinders often handle large quantities of waste that can be heavy and consist of various materials. A 2-inch waste line provides the necessary capacity to effectively manage this waste while ensuring proper flow and reducing the risk of obstruction. Smaller pipe sizes may not sufficiently handle the flow rates or the solid waste volume generated, leading to potential plumbing issues. Choosing a pipe too small can lead to slow drainage, increased risk of blockages, and a greater need for maintenance. Thus, a 2-inch diameter ensures that the system can adequately manage the operational demands of commercial food grinders and align with plumbing code requirements for safe and effective waste disposal.
