Sinks used for the washing, rinsing or sanitizing of utensils, dishes, pots, pans or service ware used in the commercial preparation, serving or consumption of food or drink shall discharge indirectly through an air gap to the drainage system. Each well of a multiple-compartment sink shall discharge independently to a waste receptor.
Exception: Where a sink is within 4 feet (1219 mm) horizontally of and located in the same room as a floor drain, the sink waste pipes may be directly connected on the sewer side of the floor drain trap, provided that the fixture waste pipes are trapped and vented as required by this chapter. No other fixture waste pipe shall be connected between the floor drain trap vent connection and the fixture being protected.
