How should the drain line of an ice machine connect to the sewer system?

The drain line of an ice machine should connect to the sewer system through an open receptacle with an air gap. This method is vital for preventing backflow, which can contaminate the potable water supply. The air gap creates a physical separation between the drain line and the sewer system, ensuring that any potential backflow from the sewer cannot siphon back into the ice machine and compromise the safety of the ice produced. This is a critical aspect of maintaining public health standards and preventing contamination in food service operations.

In food service and hospitality settings, implementing proper drainage systems is essential to comply with health regulations designed to protect consumers from waterborne contaminants.
