Equipment and fixtures utilized for the storage, preparation and handling of food, other than in dwelling units and sleeping units, shall discharge through an indirect waste pipe by means of an air gap. 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 and the fixture being protected.
