312.2
Drainage
and vent rough-in test. Drainage and vent
piping and fittings are to be tested prior to the installation of the
plumbing fixtures
and prior to the installation of wall and ceiling
coverings to verify the integrity of the system in accordance with one of the
following methods prescribed in Section 312.2.1, 312.2.2, or 312.2.3:
312.2.1
Drainage and vent rough-in water test.
A water test is to be applied to the
drainage system
either in its entirety or in sections. If applied to the
entire system, all openings in the piping are to be tightly closed, except the
highest opening, and the system is to be filled with water to the point of
overflow. If the system is tested in sections, each opening is to be tightly
plugged except the highest openings of the section under test, and each section
is to be filled with water, but sections are not to be tested with less than a
10-foot (3048 mm) head of water. In testing successive sections, not less than
the upper 10 feet (3048 mm) of the next preceding section is to be tested so
that no joint or pipe in the building, except the uppermost 10 feet (3048 mm)
of the system, is to have been submitted to a test of less than a 10-foot (3048
mm) head of water. This pressure is to be held for not less than 15 minutes.
The system is then be tight at all points.
312.2.2
Drainage and vent rough-in air test.
When permitted by the manufacturer of the piping,
fittings, and solvent cement (if part of the plumbing system), an air test is
to be made by forcing air into the system until there is a uniform gauge
pressure of 5 psi (34.5 kPa) or sufficient to balance a 10-inch (254 mm) column
of mercury. This pressure is to be held for a test period of not less than 15
minutes. Any adjustments to the test pressure required because of changes in
ambient temperatures or the seating of gaskets are to be made prior to the
beginning of the test period. Testing is to be done with dual pressure relief
valves rated for 7.5 psig.
312.2.3
Alternative drainage and vent rough-in test.
When permitted by the manufacturer of the piping,
fittings, and solvent cement (if part of the plumbing system), an alternative
method of testing the
drainage
and
vent system, such as compressed gas or vacuum, may be permitted to meet
the drainage and vent rough-in test requirements of this code as long as the
test is conducted strictly in accordance with the requirements published in the
manufacturer's installation instructions.
