Every dishwasher in a building for public use shall discharge to the drainage system through an air break or an air gap, except: (1) a domestic-type dishwasher installed under the counter in an employee break room or in any location other than a food establishment, may discharge into the sink tailpiece or food waste grinder if the discharge drain line is fastened as high as possible under the countertop; and (2) the dishwasher may be connected directly to the drainage system if a floor drain constructed without a backwater valve is installed on the individual dishwasher branch. The water supply to any dishwasher in which the supply opening is located below the spill line of the machine shall be protected with a vacuum breaker.
