A.
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.
B.
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.
C.
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.
D.
Hot water supply systems shall be provided with safety
devices arranged to relieve hazardous pressures and excessive temperatures.
A.
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.
B.
Where a public sewer is not available, a system shall
be provided to receive and dispose of sewage without health hazard
or nuisance.
C.
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.
D.
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.
E.
Each fixture directly connected to the sewage drainage
system shall be equipped with a water seal trap.
F.
Adequate cleanouts shall be provided and maintained
so that the pipes may be readily cleaned.
G.
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.
H.
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.
I.
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.
A.
Roofs and paved areas, including yards and courts,
shall be drained into dry wells provided on-site. Storm drainage shall
be conveyed to an adequate and approved dry well system of stormwater
disposal. No storm drainage shall be discharged in such manner as
to permit water to flow onto sidewalks. However, the provisions of
this section shall not prohibit the continuation of any previously
existing system of stormwater disposal, except where the Superintendent
of Public Works determines that such previously existing system is
dangerous to public health, safety or welfare. Any such determination
by the Superintendent of Public Works may be appealed to the Board
of Trustees.

of noncombustible material, except that wood leaders and gutters may
be used for buildings not more than three stories high.
