A. Food Handling.

1. Exception. An air gap (drainage system) is the only acceptable method of indirectly connecting any food handling equipment wherein the indirect waste pipe may be under a vacuum.

B. Commercial Dishwashing Machines. Commercial dishwashing machines shall be indirectly connected.

C. Connections. The following types of connections shall be indirect waste connections in accord with the specifications stated below.

1. Water Supply Connections. Drains, overflows or relief lines from the water distribution system shall waste into an indirect waste receptor through an air gap (water distribution).

2. Air Conditioning Unit Connections. Indirect waste connections shall be provided for drains, overflows, or relief lines from air conditioning units.

D. Sterile Materials. Appliances, devices, or apparatus such as stills, sterilizers, and similar equipment, requiring water and waste connections and used for sterile material, shall be indirectly connected or provided with an air gap (drainage system) between the trap and the appliance.

E. Drips. Appliances, devices, or apparatus not regularly classed as plumbing fixtures but which have drips or drainage outlets shall be drained by indirect waste pipes discharging into an open receptacle as provided in §805 of this code.

F. Cleanliness. The sink or receptor receiving indirect wastes shall be water-supplied if the waste stream contains or is expected to contain a sufficient amount of organic matter capable of causing odors or otherwise causing a nuisance due to an insufficient dilution of the waste material discharged into the sink or receptor.

G. Receptors. Waste/plumbing receptors serving indirect waste pipe discharges shall meet the following requirements.

1. Installation. Waste receptors serving indirect waste pipes shall not be installed in any toilet room, nor in any inaccessible or unventilated space such as a closet or storeroom.

2. Strainers and Baskets. Every indirect waste receptor receiving discharge containing particles that would clog the receptor shall be equipped with a basket or other device which shall prevent passage into the drainage system of solids 1/2-inch (12.7 mm) or larger in size. The basket or device shall be removable for cleaning purposes.

3. Splashing. All plumbing receptors receiving the discharge of indirect waste pipes shall be of such shape and capacity as to prevent splashing or flooding. No plumbing fixture which is used for domestic or culinary purposes shall be used to receive the discharge of an indirect waste pipe.

H. Clear Water Wastes. Water lifts, expansion tanks, cooling jackets, sprinkler systems, drip or overflow pans or similar devices which waste clear water only, shall discharge into the building drainage system through an indirect waste.

J. Drinking Fountains. Drinking fountains may be installed with indirect wastes.

K. Swimming Pools. Piping carrying waste water from swimming or wading pools, including pool drainage, backwash from filters, water from scum gutter drains or floor drains which serve walks around pools, shall be installed as an indirect waste utilizing a circulation pump, if necessary, when indirect waste line is below the sewer grade(S).

L. Residential Washing Machines (clothes washers). All residential washing machines shall connect to the building drainage system via an individual indirect waste pipe for each machine using one of the indirect waste methods specified in §805 of this code.

1. Any machines which discharge by gravity shall discharge into an adequately sized individual receptor, such as a floor sink. Such receptor/floor sink shall be properly trapped, vented, and directly connected to the drainage system.

M. Commercial Laundry Machines. All commercial laundry washing machines shall connect to the building drainage system via an individual indirect waste pipe for each machine using one of the indirect waste methods specified in §805 of this code.

1. Any machines which discharge by gravity shall individually discharge into an adequately sized receptor trough/pit or adequately sized individual receptors, such as floor sinks. Such receptor trough/pit or floor sinks shall be properly trapped, vented, and directly connected to the drainage system.
