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 Plumbing 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 Plumbing Inspector and as directed by him or her under
a water test.
B. The water test shall be applied by securely closing
all openings and filling pipes to the highest opening above the floor
with 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 provisions 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.
C. 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 Plumbing Inspector and as directed by him or
her.
D. 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 the State Uniform Fire Prevention and Building
Code applicable to plumbing and this chapter.
[Amended 2-9-1981 by L.L. No. 1-1981]
E. Where, in the judgment of the Plumbing 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 or herself and the owners of such building from the Plumbing
Inspector a certificate of inspection, duly signed by the Plumbing
Inspector, certifying that the plumbing work has been properly inspected
and tested as required by the provisions of this chapter.
