     1. There may be no direct connection between the sewerage and any drains originating from equipment in which food, ice, portable equipment or utensils are placed.

     2. If a dishwashing machine is located within 5 feet (1.52 meters) of a floor drain with a trap, the waste outlet for the dishwasher may be connected directly to the drain on the side containing the inlet if the trap is properly vented.

     3. A walk-in refrigerator must have a floor which is graded so that it drains to the outside through a waste pipe, doorway or other opening. The health authority may authorize a floor drain with an approved device to prevent backflow in a walk-in refrigerator if the slope of the floor is extreme.

     4. Every drain, overflow or relief vent from the water supply system must have an indirect connection to the waste system. Drain lines from equipment must not discharge wastewater in a manner that floods any floor or causes water to flow across any work area or area which is difficult to clean.

     5. A floor drain must be provided in any area where meat, fish or poultry is processed.
