An air gap and an air break both prevent contaminated water from flowing back into a fixture, but they are not the same. The difference is a matter of distance and what each protects.
The air gap
An air gap is a complete, unobstructed vertical space between the water outlet and the drain, and it is the strongest protection against backflow.
The air break
An air break is a smaller, partial separation that lets water drain indirectly without the full vertical gap.
The use
An air gap is required where backflow could contaminate, like a dishwasher or a water softener drain, while an air break suits some indirect waste lines.
The code
The plumbing code specifies which fixtures need which. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Calexico, the inspector checks the gap.
