[Amended 8-12-1974 by L.L. No. 7-1974[1]]
Every new plumbing system or addition to an
old system for which a permit is required shall be tested by the plumber
in the presence of the Building Inspector in accordance with the following
subsections of this section:
A.
The entire new plumbing and drainage system within
the building, when roughed in, shall be tested by the plumber in the
presence of the Building Inspector and as directed by him under either
a water test or a smoke test.
(1)
The water test shall be applied by securely
closing all openings and filling pipes to the highest opening above
the floor with the water, except that part of the system may be tested
separately, provided that there shall be a head of water of at least
10 feet above all parts of the work so tested. Special provision shall
be made to include all joints and connections to the finished line
or face of floors or side walls so that all vents and back vents,
including lead work, may be tested with the main stacks. All pipes
shall remain uncovered in every part until they have satisfactorily
passed the test; or
(2)
After the completion of the work and when the
fixtures are installed, a smoke test under a pressure of one-inch
water column will be required of the system, including all vent and
back vent pipes, in the presence of the Building Inspector and as
directed by him.
B.
All defective pipes and fittings or fixtures shall
be removed, and all defective work shall be made good so as to conform
to the provisions of this code.
C.
Where, in the judgment of the Building Inspector,
it is impractical to apply tests mentioned in this section only on
alterations and additions to old work, such work shall be thoroughly
inspected if not tested.
When the plumbing in a building is completed
for which a permit is required, the master plumber shall secure for
himself and the owners of such building, from the Building Inspector,
a certificate of inspection duly signed by him, certifying that the
plumbing work has been properly inspected and tested as required by
the provisions of this code.
