A. General requirements. (1) Plumbing systems shall be maintained in a sanitary and serviceable condition. (2) Plumbing systems shall be maintained so as not to weaken structural members nor cause damage or deterioration to any part of the building through fixture usage. B. Water supply. (1) Potable water from an approved source shall be available at all times in residential buildings. The domestic water supply system of the building shall be connected to such approved source and shall not be subject to contamination. When supplied from a public source, the potable water supply system shall not be connected to private or unsafe water supplies. (2) Water supply systems shall be installed and maintained so as to provide at all times a supply of water to plumbing fixtures, devices and appurtenances in sufficient volume and at pressures adequate to enable them to function satisfactorily and without undue noise under all normal conditions of use. (3) Water supply systems shall be installed and maintained so that water used for purposes of cooling or heating shall not be reintroduced into the domestic water supply system nor be distributed through such equipment to plumbing fixtures. (4) Hot-water supply systems shall be provided with safety devices arranged to relieve hazardous pressures and excessive temperatures. C. Sewage drainage system. (1) Plumbing fixtures shall be drained to a sewage drainage system, and such system shall be connected to a public sewer or to an adequate and approved system of sewage disposal. (2) Where a public sewer is not available, a system shall be provided to receive and dispose of sewage without health hazard or nuisance. (3) Sewage or other waste which may be deleterious to surface or subsurface waters shall not be discharged into the ground or into a waterway, unless it has first been rendered harmless through subjection to treatment in conformity with generally accepted standards. (4) Substances which will clog the pipes, produce explosive mixtures, destroy the pipes or their joints or interfere unduly with the sewage disposal process shall not be discharged into the building drainage system, unless it is provided with approved devices suitable for intercepting such substances. (5) Each fixture directly connected to the sewage drainage system shall be equipped with a water-seal trap. (6) Adequate cleanouts shall be provided and maintained so that the pipes may be readily cleaned. (7) The drainage system and its attendant vent piping shall be maintained so as to provide adequate circulation of air in all pipes in order that siphonage, aspiration or pressure will not cause a loss of trap seal under ordinary conditions of use. (8) Each vent terminal to the outer air shall be installed and maintained so as to minimize the possibilities of clogging, frost closure, the return of foul air to the building or the creation of a nuisance to adjacent premises. (9) Drains provided for fixtures, devices, appliances or apparatus containing food, water, sterile goods or similar materials shall be equipped with air breaks adequate to prevent contamination of such contents from any possible backup of sewage through the direct or indirect drainage piping. D. Storm drainage. (1) Roofs and paved areas, including yards and courts, shall be drained. Storm drainage shall be conveyed to an adequate and approved system of stormwater disposal where available. Storm drains shall be discharged in such manner that water will not flow onto sidewalks. (2) Where a drainage system may be subject to backwater, suitable provisions shall be made to prevent its overflow into the building. (3) Leaders and gutters, if used, shall be constructed of noncombustible material, except that wood leaders and gutters may be used for buildings not more than three stories high. E. Plumbing facilities. (1) Buildings and portions thereof shall be provided with plumbing systems designed to dispose of the sewage from all fixtures and to furnish cold water to every water closet and urinal and hot and cold water to every sink, lavatory, bathtub and shower required therein.
