(vii) The domestic hot water system shall make provisions to limit the amount of Legionella bacteria and opportunistic waterborne pathogens. (viii) Domestic water storage tank(s) shall be fabricated of corrosion-resistant metal or lined with noncorrosive material. When potable water storage tanks (hot and cold) are used, the water shall be used and replenished. Water shall not be stored in tanks for future use unless the water is tested weekly for contaminates/bacteria. (ix) Purified water distribution system piping shall be task specific and include, but not necessarily be limited to, polypropylene (PP), polyvinylidene fluoride (PVDF) or polyvinyl chloride (PVC) pipe. Final installed purified water system piping assemblies shall be UL approved and fully comply with applicable American Society for Testing and Materials (ASTM) Fire Resistant/Smoke Density requirements. The applicable documents are available from ASTM International, 100 Barr Harbor Drive, Post Office Box C700, West Conshohocken, Pennsylvania 19428-2959. (B) When fire sprinkler systems are required and provided in an ESRD facility, the fire sprinkler systems shall be designed, installed, and maintained in accordance with the requirements of NFPA 13, and shall be certified as required by §117.105(c)(1)(C) of this title (relating to Construction, Inspections, and Approval of Project). (C) Main storage of medical gases may be outside or inside the ESRD facility in accordance with NFPA 99, §5.1. (D) Steam and hot water systems. (i) When boilers are used the boilers shall have the capacity, based upon the net ratings as published in The I-B-R Ratings Book for Boilers, Baseboard Radiation and Finned Tube (commercial) by the Hydronics Institute Division of GAMA, to supply the normal requirements of all systems and equipment. The document published by the Hydronics Institute Division of GAMA as referenced in this rule may be obtained by writing or calling the Hydronics Institute Division of GAMA at 35 Russo Place, P.O. Box 218, Berkeley Heights, New Jersey 07922, telephone (908) 464-8200. (ii) Boiler feed pumps, heating circulating pumps, condensate return pumps, and fuel oil pumps shall be connected and installed to provide normal and standby service. (iii) Supply and return mains and risers of cooling, heating, and process steam systems shall be valved to isolate the various sections of each system. Each piece of equipment shall be valved at the supply and return ends except that vacuum condensate returns need not be valved at each piece of equipment. (E) Drainage systems. (i) All underground building drains shall be: cast iron soil pipe, hard temper copper tube (drain-waste-vent (DWV) or heavier), acrylonitrile-butodiene-styrene (ABS) plastic pipe (DWV Schedule 40 or heavier), polyvinyl chloride (PVC) plastic pipe (DWV Schedule 40 or heavier), or extra strength vitrified clay pipe (VCP) with compression joints or couplings with at least 12 inches of earth cover. (ii) Soil stacks, drains, vents, waste lines, and leaders installed above ground within buildings shall be DWV weight or heavier and shall be: copper pipe, copper tube, plastic pipe (DWV scheduled 40 or heavier) cast iron pipe, or galvanized iron pipe. (iii) Drainage systems for chemical wastes (acids and other corrosive materials) shall be provided. Materials acceptable for chemical waste drainage systems shall include chemically resistant glass pipe, high silicone content cast iron pipe, VCP, CPVC plastic pipe, or plastic lined pipe. (iv) Thermal insulation for piping systems and equipment shall be provided for the following: (I) boilers, smoke breeching, and stacks; (II) steam supply and condensate return piping; (III) hot water piping and all hot water heaters, generators, converters, and storage tanks; (IV) chilled water, refrigerant, other process piping, equipment operating with fluid temperatures below ambient dew point, and water supply and drainage piping on which condensation may occur. Insulation on cold surfaces shall include an exterior vapor barrier; and (V) other piping, ducts, and equipment as necessary to maintain the efficiency of the system. (v) Flame spread shall not exceed 25 and smoke development rating shall not exceed 50 for pipe insulation as determined by an independent testing laboratory in accordance with National Fire Protection Association 255, Standard Method of Test of Surface Burning Characteristics of Building Materials, 2000 Edition. Smoke development rating for pipe insulation located in environmental air areas shall not exceed 50. (vi) Asbestos insulation shall not be used. (2) Plumbing fixtures shall be made of nonabsorptive acid-resistant materials and shall comply with the recommendations of the National Standard Plumbing Code and this paragraph. (A) All sinks used by medical and nursing staff and all lavatories used by patients shall be trimmed with valves which can be operated without the use of hands.
