All piping, traps and fixtures of a plumbing
system shall be inspected by the proper administrative authority to
ensure compliance with all the requirements of this chapter and the
installation and construction of the system in accordance with the
approved plans and the permit.
The equipment, material, power and labor necessary
for the inspection and test shall be furnished by the plumber.
All the piping of a plumbing system shall be
tested with water or air. After the plumbing fixtures have been set
and their traps filled with water, the entire drainage system shall
be submitted to a final air pressure test. The proper administrative
authority may require the removal of any cleanouts to ascertain if
the pressure has reached all parts of the system.
The tests may be made separately, as follows:
A. The house sewer and all its branches from the property
line to the house drain.
B. The house drain, including all piping to the height
of 10 feet above the highest point on the house drain except the exposed
connections to fixtures.
C. The soil, waste, vent, inside conductor and drainage pipes which would be covered up before the building is enclosed or ready for completion. The tests required for Subsections
B and
C may be combined.
D. The final test of the whole system.
No drainage or plumbing system or part thereof
shall be covered until it has been inspected, tested and approved
as herein prescribed.
If any house drainage or plumbing system or
part thereof is covered before being regularly inspected, tested and
approved as herein prescribed, it shall be uncovered upon the direction
of the proper administrative authority.
If the inspection or test shows defects or inadequacies, such defective or inadequate work or material shall be replaced within three days and another inspection and test shall be called for as provided in §
152-132. A fee of $5 for every reinspection shall be paid at or before issuance of a certificate of approval.
If a stable or garage or any part of a stable
or garage is to be used for human habitation, the same inspections
and tests of plumbing and drainage systems thereof shall be made as
in the case of an ordinary dwelling. Otherwise, all stable and garage
drains shall be inspected but need not be tested.
Upon the completion of the entire water distribution
system, it shall be tested and proved tight under a water pressure
not less than the maximum working pressure under which it is to be
used.
Upon the satisfactory completion and final test
of the plumbing system, a certificate of approval will be issued by
the proper administrative authority to the plumber, to be delivered
to the owner. No plumbing work for which an inspection or test is
required by this chapter shall be used unless a certificate of approval
has been issued.
No tests or inspections shall be required where
a plumbing system or part thereof is not used for toilet purposes
but is set up merely for exhibition purposes and is not directly connected
to a sewage disposal system; nor after the repair or replacement of
an old fixture, faucet or valve by another one to be used for the
same purpose; nor after forcing out stoppages and repairing leaks.
