All new plumbing work and such portions of existing systems as may be affected by new work
or any changes shall be inspected within 6 months from the date of filing plans (unless permission for an extension of
time is requested in writing by the plumber and granted by the Department) to insure compliance with this code and,
where drawings form part of the permit, to verify that the installation and construction of the system are in accordance
with the approved drawing.
An inspection shall be required for all work for which a permit is required
by this code, and tests shall be required for all new installations of plumbing systems and whenever new, relocated,
or replacement stacks, interior leaders, building drains, or part thereof, are installed, or major horizontal branches or
branch vents are connected thereto.
The work should be tested and ready before inspection, and no work shall be
covered without authorization from the Department. A call shall be made by the plumber in the event he or she is not
ready for inspection.
The equipment, material, power, and labor necessary for the inspection and test shall
be furnished by the plumber. Each soil stack and rain leader shall be provided with a test fitting. When of the type
having an iron pipe size threaded opening, such openings shall be permitted to be used as a cleanout when installed in
accordance with Section P-507.1.
Shoring shall be installed in ditches and trenches as per OSHA regulations or as regulated by the
Department. In some instances, sloping the sides of the excavation as per OSHA will satisfy this requirement if the
earth is suitable for this application. Violation of this provision will result in a Stop Work Order and/or penalties
prescribed by law.
Where there is reason to believe that the drainage and vent system of any building has
become unsanitary or defective, such drainage and vent system shall be subject to an appropriate test as determined
by the Department.
The piping of drainage and vent systems shall be tested with water or air in accordance with
Sections P-1506.2 or P-1506.3 when inspection is required by Section P-1501. Water tests shall not be used in freezing
weather. Cleanouts or plugs shall be removed and traps unsealed, if requested by the Department, to ascertain whether
the test medium has reached all parts of the system. After the plumbing fixtures have been set and their traps filled
with water, the entire drainage system shall be submitted to final inspection.
A water test shall be applied to the drainage and vent system in its entirety or in sections. If
tested in sections, not more than 30 feet in height on any one system shall be tested at any one time. If applied to the
entire system, all openings in the piping shall be tightly closed - except the highest - opening and the system filled
with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged (except
the highest opening of the water) but no section (except the house drain and its connected yard and area drains) shall
be tested with less than a 10-foot head of water. In testing successive sections above the house drain, at least the upper
10 feet of the next preceding section shall be re-tested so that no joint or pipe in the building (except the house drain
and the uppermost 10 feet of the system) shall have been submitted to a test of less than a 10-foot head of water. The
water shall be kept in the system or in the portion under test for at least 15 minutes before inspection starts; the system
shall then be tight at all points.
The house drain and yard area drains, including all piping to a height of 2 feet above the
highest point of the house drain, shall be tested separately. All traps, pipe fittings and joints shall be exposed to
view when the test is made. Water shall be introduced into the system in the quantity deemed necessary by the
Department. To be approved, the flow of water through the system shall be unobstructed, and there shall be no
leakage through any pipe, joint, trap, or fitting.
The air test shall be made by attaching an air compressor or testing apparatus to any suitable
opening and, after closing all other inlets to the system, by forcing air into the system until there is a uniform gauge
pressure of 5 psi. This pressure shall be held without the introduction of additional air for a period of at least 15
minutes. Wooden plugs shall not be used to close openings.
Upon the completion of a section or of an entire water supply system, that section or system
shall be tested and proved tight under a water pressure not less than the working pressure under which it is to be used.
After tests have been made and approved by the inspector, covering, insulation,
coating or painting of the drain, vent and water piping shall be permitted. Decals on soil, waste, and vent piping, and
hot, cold and return water piping shall be installed every 10 feet on covered and uncovered lines.
