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. (5) Separate building units shall have their own water supply with separate curb box shutoff outside the building. C. Sewage drainage systems. (1) Plumbing fixtures shall be drained to a sewage drainage system, and such system shall be connected to a public sewer or to an approved system of sewage disposal. (2) Where a public sewer is not available, sewage or other waste 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 the rules and regulations of the Department of Health. (3) 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's drainage system unless it is provided with approved devices suitable for intercepting such substances. (4) Each fixture directly connected to the sewage drainage system shall be equipped with a water-seal trap. (5) Adequate cleanouts shall be provided and maintained so that the pipes may be readily cleaned. (6) 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. (7) 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. D. Storm drainage. (1) 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 provision shall be made to prevent its overflow into the building.
