§ 81.20 Plumbing and Water Supply.
RCNY § 81.20
(a)Potable water supply. Establishments at all times must have adequate supplies of potable water, as defined in Part 5 of the State Sanitary Code (10 NYCRR Chapter 1). An establishment shall be equipped with plumbing and plumbing fixtures, in accordance with applicable law, that safely supply potable water to all parts of the establishment. Plumbing and fixtures shall be properly connected, vented, and drained to prevent contamination of the potable water supply. Potable water supply fixtures or other equipment connected to the potable water supply shall be designed and constructed or equipped with a device that prevents back-flow or siphonage into, or cross connection with the water supply.
(b)Disposal of sewage and liquid waste. Sewage and liquid wastes including but not limited to condensates discharged by equipment, such as refrigerators, ice machines, air conditioners, drain pans, evaporator trays, hoses and other plumbing or cooling lines and fixtures; fluids drained from culinary, slop or ware washing sinks; and fluids discarded after cooking shall be conveyed to the sewer or sewage disposal system so as to prevent contamination of the premises and its contents and so as not to create harborage conditions. Liquid wastes consisting of discarded grease and oil shall be disposed of in accordance with applicable laws.
(1)Indirect waste connection required. There shall be no direct connection between the sewage system and any drains from plumbing fixtures and equipment used for hot and cold storage, or mechanical processing of food. Waste lines from equipment required to have indirect drains shall be installed to prevent back-flow from sewers and other drains and waste lines.
(2)Direct connections required. Waste water shall be discharged into properly trapped, sewer-connected plumbing lines.
(c)Carbonated beverages. All plumbing lines conducting carbon dioxide gas or carbonated beverages shall be manufactured from stainless steel, food-grade plastic or other material that will not produce toxic substances when exposed to carbon dioxide or carbonated water.
