How deep must a commercial food waste grinder be with its drain?

1 inch
1.5 inches
2 inches
3 inches

The correct answer is: 1.5 inches

A commercial food waste grinder must have its drain set at a depth of 1.5 inches to ensure proper functionality and prevent issues such as clogs or inadequate drainage. This depth allows for optimal drainage of food waste and grease, which is critical for maintaining sanitary conditions and effective waste disposal in a commercial kitchen setting. The 1.5-inch depth aligns with plumbing codes and standards that aim to promote efficient drainage systems in food service establishments. Maintaining this depth is essential for enabling appropriate flow rates and avoiding backflow, which can lead to contamination or inefficiencies in waste removal processes.
