18-29-802.1 Where required.
   Food-handling equipment in other than dwelling units and sleeping units, clear-water waste, humidifiers, commercial dishwashing machines and utensil, pot, pan and dishwashing sinks shall discharge though an indirect waste pipe as specified in Sections 18-29-802.1.1 through 18-29-802.1.7. Fixtures not required to be indirectly connected by this section and the exception to Section 18-29-301.6 shall be directly connected to the plumbing system in accordance with Article 7.
(Amend Coun. J. 10-14-21, p. 37722, Art. VIII, § 1)
18-29-802.1.1 Food handling.
   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.
(Amend Coun. J. 10-14-21, p. 37722, Art. VIII, § 1)
18-29-802.1.2 Floor drains in food storage areas.
   Floor drains located within walk-in refrigerators or freezers in food service and food establishments shall be indirectly connected to the sanitary drainage system by means of an air gap. Where a floor drain is located within an area subject to freezing, the waste line serving the floor drain shall not be trapped and shall indirectly discharge into a waste receptor located outside of the area subject to freezing.
   Exception: Where protected against backflow by a backwater valve, such floor drains shall be indirectly connected to the sanitary drainage system by means of an air break or air gap.
(Amend Coun. J. 10-14-21, p. 37722, Art. VIII, § 1)
18-29-802.1.3 Potable clear-water waste and swimming pools.
   Where devices and equipment, such as sterilizers and relief valves, discharge potable water to the building drainage system, the discharge shall be through an indirect waste pipe by means of an air gap.
   Where wastewater from swimming pools, backwash from filters and water from pool deck drains discharge to the building drainage system, the discharge shall be through an indirect waste pipe by means of an air gap.
(Amend Coun. J. 10-14-21, p. 37722, Art. VIII, § 1)
18-29-802.1.4 Nonpotable clear-water waste.
   Where devices and equipment, such as safe pans, drip pans, process tanks, filters, drips and boilers, discharge nonpotable water to the building drainage system, the discharge shall be through an indirect waste pipe by means of an air break or an air gap.
18-29-802.1.5 Waste piping.
   Waste piping from aspirators, sterilizers or any other equipment which would produce a partial vacuum by cooling shall discharge to the drainage piping system through an air gap into a waste receptor. The minimum size shall be 1 inch (25 mm) and the maximum length of the indirect waste shall not exceed 15 feet (4.57 m) and shall be provided with cleanouts at every 90 degree turn which are accessibly located. Each indirect waste pipe shall be individually piped to the waste receptor with material that is required by this chapter. Waste receptors serving indirect pipes connected to the above equipment shall be located in the same room. Each waste receptor shall be trapped and vented as required by this chapter. The air gap shall be not less than two times the diameter of the indirect waste pipe.
18-29-802.1.6 Commercial dishwashing machines.
   The discharge from a commercial dishwashing machine shall be through an air gap into a waste receptor in accordance with Section 18-29-802.3.
   Exception: Where the fixture is within 4 feet (1219 mm) horizontally of and located in the same room as a floor drain, the fixture waste pipe may be directly connected on the sewer side of the floor drain trap, provided that the fixture waste pipe is 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.
(Amend Coun. J. 10-14-21, p. 37722, Art. VIII, § 1)
18-29-802.1.7 Sinks.
   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.
