A floor sink and a floor drain look similar, but they serve different jobs in a commercial kitchen or mechanical room. Picking the wrong one can mean a code violation or a slow drain.
The floor sink
A floor sink is a recessed basin that receives indirect waste from equipment like a dishwasher or an ice machine, with an air gap to prevent backflow.
The floor drain
A floor drain is a flush grate that carries away surface water from spills and washdowns, and it usually connects directly to the line.
The difference
The key distinction is the air gap: a floor sink provides an indirect connection, while a floor drain is a direct connection. That gap is what protects the equipment and the water supply.
The placement
Floor sinks go under fixtures that discharge food or condensate; floor drains go where the floor gets wet. hard water is common across the region, and older neighborhoods still have galvanized supply lines In Auburn, health codes often dictate the layout.
The common mistake
Connecting a food-prep fixture directly to a floor drain can be a code violation because it lacks the required air gap. That distinction is what inspectors check first.
