[Amended 11-11-1980]; 10-22-1996; 3-13-2001 by L.L. No. 1-2001; 4-22-2014 by L.L. No. 1-2014]
All piping, traps and fixtures of a plumbing system or installation
of electrical fixtures hereafter installed shall be inspected by the
inspector to ensure compliance with all the requirements of this code
and the installation and construction of the system in accordance
with approved plans and permit, for which inspection a fee shall be
collected from the plumber according to the following schedule:
A.Â
It shall be the duty of the plumber or electrician to notify the
inspector, in writing, not less than 48 hours before the work is to
be inspected or tested.
B.Â
It shall be the duty of the plumber or electrician to be reasonably
certain that the work will stand the test prescribed before giving
the above notification.
The equipment, material, power and labor necessary for the inspection
and test shall be furnished by the plumber or electrician.
A.Â
All the piping of a plumbing system hereafter constructed shall be
tested with water. After the plumbing fixtures have been set and their
traps filled with water, the entire drainage system shall be submitted
to a final peppermint or smoke test in the presence of the inspector.
The inspector may require the removal of cleanouts to ascertain if
the pressure has reached all parts of the system.
B.Â
A piped-up air test shall be made of the repair, replacement or installation
of any residential or commercial oil or gasoline storage tank.
C.Â
Prior to the installation of any natural or liquefied-petroleum-gas-fired
appliance, a mercury or water column test shall be made on any supply
pipe or roughing leading to the appliance.
D.Â
All wet-pipe or fire line service sprinklers, standpipes or connections
shall be subject to a two-hundred-pound static test, both within the
building, at the curb valve or from the trunk line to the point of
entry. (All structures containing a wet pipe sprinkler system shall
be required to maintain on premises a minimum of five extra sprinkler
heads that will fit the system.)
E.Â
Electrical tests shall require energizing all electrical appliances
and related equipment approved by the Building Inspector and/or the
inspector.
A.Â
The water test may be applied to the drainage system in its entirety
or in sections. If applied to the entire system, all openings in the
piping shall be tightly closed, except the highest opening above the
roof, and the system filled with water to the point of overflow above
the roof.
B.Â
If the system is tested in sections, each opening shall be tightly
plugged, except the highest opening of the section under test, and
each section shall be filled with water, but no section shall be tested
with less than 20 feet of water. In testing successive sections, at
least the upper 10 feet of the next preceding section shall be retested
so that no joint nor pipe in the building shall have been submitted
to a test of less than 20 feet head of water.
C.Â
Under any test, the water level shall remain constant for not less
than 15 minutes without any further addition of water.
D.Â
The piped-up air test shall consist of piping compressed air into
the fuel storage tank. In the case of a steel storage tank, said tank
must withstand a pressure of no less than seven pounds per square
inch as measured by a pressure gauge. In the case of a fiberglass
storage tank, said tank must withstand a pressure of not less than
10 pounds per square inch as measured by a pressure gauge.
E.Â
Mercury and water column tests. Before any appliances are connected,
piping or roughing shall stand a pressure of at least six inches of
mercury or three pounds' gauge for at least 10 minutes without
showing any drop in pressure. Pressure shall be measured with a mercury
manometer or slope gauge or any equivalent device calibrated to read
in increments of not greater than 0.1 pound. The source of pressure
shall be isolated before the pressure tests are made. Liquefied-petroleum-gas
systems shall stand a pressure of not less than a ten-inch water column
for a period of not less than 10 minutes without showing any drop
in pressure. Pressure shall be measured with a water manometer or
an equivalent device calibrated to read in increments of not less
than one-tenth-inch water column. The source of pressure shall be
isolated before the tests are made.
F.Â
Two-hundred-pound static test. To determine the value of public water
as a supply to a wet-pipe or fire service line sprinkler, standpipe
or connection, a gauge shall be attached at the curb valve or within
the building or, in the case of the fire service line sprinkler, standpipe
or connection, a gauge shall be attached at the trunk line. In both
cases, the water pressure shall measure no less than 200 pounds per
square inch at the point tested and shall maintain said pressure for
a period of no less than two hours.
The tests shall be made separately as follows:
A.Â
The house drain, including all piping to the height of 20 feet above
the highest point of the house drain, except the exposed connections
to fixtures.
B.Â
The soil, waste, vent and drainage pipes which would be covered up
before the building is enclosed or ready for completion.
C.Â
The final smoke test of the whole system.
No plumbing or electrical system nor part thereof shall be covered
until it has been approved as herein prescribed.
A.Â
Upon the satisfactory completion and final test of the plumbing or
electrical system, a certificate of final inspection shall be issued.
B.Â
A triplicate record shall be kept by the inspector of all inspections
made by him, the original to be filed at the Building Inspector's
office, the duplicate copy to be for the use of the inspector, and
the triplicate copy for the plumber or electrician. These records
are to contain the type of house, the number and kind of plumbing
or electrical fixtures, the date and time of inspection, the name
of the owner, the name of the licensed plumber and the fee paid.
C.Â
The certificate of final inspection shall be signed by the Inspector
and filed in the office of the Building Inspector. No plumbing or
electrical fixtures shall be used until said certificate of final
inspection has been issued by the inspector. No certificate of compliance
shall be issued by the Building Inspector, where plumbing or electrical
work is involved, until the certificate of final inspection of the
plumbing or electrical work by the inspector has been filed.
