Every building hereafter erected and also every existing building,
other than residence buildings occupied exclusively by one or two
families and having not more than 15 sleeping rooms, which may be
supplied from some outside source with gas, vapor or fluid, except
potable waters, shall have a conveniently accessible stopcock or other
suitable device fixed to the supply pipes leading into the building
at a place outside of the building, so arranged as to allow the supply
to be shut off. Such stopcock or other device shall be so marked as
to indicate either the contents and purposes of the supply pipe to
which it is attached or the company to which the device belongs, and,
in addition, shall comply with any state code requirements.
No person shall use or permit the use of any new system of plumbing
and drainage hereafter installed in any building before the same has
been tested under the supervision of the Building Department and in
accordance with its rules, to ensure the tightness of the system,
nor until a proper and adequate water supply has been provided. The
Superintendent of Buildings shall, within a reasonable time after
being requested to do so, cause to be inspected and tested any system
of plumbing and drainage that is ready for such inspection and test,
and if the work is found satisfactory and the test requirements are
complied with, he shall issue a certificate to that effect. Nothing
herein contained shall prevent the inspection and test of part of
a system or the issuance of a partial certificate, nor prevent the
use of such part of a larger system, provided that such part constitutes
by itself a complete system, properly tested and supplied with water.
No person shall use or permit the use of any new system or an
extension of an old system of gas piping in any building before the
same has been inspected and tested under the supervision of the Building
Department and in accordance with its rules, to ensure the tightness
of its system. The Superintendent of Buildings shall, within a reasonable
time after being requested to do so, cause to be inspected and tested
any system of gas piping that is ready for such inspection and test,
and if the work is found satisfactory and the test requirements are
complied with, he shall issue a certificate to that effect. Nothing
herein contained shall prevent the use of existing systems of gas
piping without further inspection or test, unless the Superintendent
of Buildings has reason to believe that defects exist which make the
system dangerous to life or property.
No plumbing work shall be started until a permit has been obtained
from the Superintendent of Buildings.
