installed with a fall of not less than one-
eighth inch per foot.
Sec. 28-1069. 3 . Minimum velocity. Where
conditions do not permit building drains and
sewers to be laid with a fall as great as that
specified, then a lesser slope may be permitted
providing the computed velocity will be not
less than 2 feet per second. (See appendix
Gen. 11. 3 .4, state plumbing code 1964. )
Sec. 28-1070. values for Fixtures . Fixture-unit
values as given in table 70 designate the relative

Sec. 28-1071. 3 . Minimum Size of Soil and Waste
Stacks . No soil or waste stack shall be smaller
than the largest horizontal branch connected
thereto except that a 4 x 3 w. c. connection shall
not be considered as a reduction in pipe size.
No main house sewer or drain shall be less than
4 inches in diameter.
Sec. 28-1071.4. Minimum Size of Stack-vent or
Vent Stack. Any structure on which a building
drain is installed shall have at least one
stack-vent or vent stack carried full size
through the roof not less than 3 inches in
diameter.
Sec. 28-1071. 5 . Future Fixtures . When provision
is made for the future installation of fixtures ,
those provided for shall be considered in deter-
mining the required sizes of drain pipes .
Construction to provide for such future installa .
tion shall be terminated with a plugged fitting
or fittings at the stack so as to form no dead
end.
Sec. 28-1072. Offsets of 45 Degrees or less . An
offset in a vertical stack, with a change of direction
of 45 degrees or less from the vertical, may be sized
as a straight vertical stack. In case a horizontal
branch connects to the stack within 2 feet above or
below the offset, a relief vent shall be installed in
accordance with section 28-1095 . 2.
Sec. 28-1072. 1. Waste Stacks Serving Kitchen
Sinks . In a one- or two-family dwelling only
in which the waste stack or vent receives the
discharge of a kitchen-type sink and also serves
as a vent for fixtures connected to the horizon-
tal portion of the branch served by the waste
stack, the minimum size of the waste stack up
to the highest sink branch connection shall be
2 inches in diameter. Above that point the
size of the stack shall be governed by the total
number of fixture units vented by the stack.
Sec. 28-1072 . 2. Above Highest Branch. An
offset above the highest horizontal branch is an
off-set in the stack-vent and shall be considered
only as it affects the developed length of the
vent.
Sec. 28- 1072. 3 . Below Lowest Branch. In the
case of an offset in a soil or waste stack below
the lowest horizontal branch, no change in
diameter of the stack because of the offset
shall be required if it is made at an angle
not greater than 45 degrees . If such an offset
is made at an angle greater than 45 degrees ,
the required diameter of the offset and the
stack below, it shall be determined as for a
building drain. (See table 71. 1. )

Sec. 28-1072.4. Offsets of More Than 45 Degrees .
A stack with an offset of more than 45 degrees
from the vertical shall be sized as follows :
The portion of the stack above the offset shall
be sized as for a regular stack based on the total
number of fixture units above the offset.
The upper portion of the stack above the offset
shall be sized as for a building drain. (See
table 71. 1, column 5 . )
A relief vent for the offset shall be installed
as provided and in no case shall the horizontal
branch connect to the stack within 2 feet above
or below the offset.

Sec. 28-1108. Requirements . No drainage or plumbing
system or part thereof shall be covered until it has
been inspected, tested, and accepted as prescribed
in this chapter.
Sec. 28-1108. 1. Uncovering. If any building
drainage or plumbing system or part thereof
which is installed, altered, or repaired, is
covered before being inspected, tested, and
approved, as prescribed in this section, it shall
be uncovered for inspection after notice to
uncover the work has been issued to the respon-
sible person by the plumbing inspector.
Sec. 28-1109. Who Furnishes . The equipment, material,
and labor necessary for inspection or tests shall be
furnished by the person to whom the permit is issued
or by whom inspection is requested.
Sec. 28-1110. Tests Required. The piping of the
plumbing, drainage, and venting systems 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 inspection.
The plumbing inspector may require the removal of any
cleanouts , to ascertain if the pressure has reached all
parts of the system.
Sec. 28-1110. 1. Air Test. The air test shall be
made by attaching an air compressor testing appar-
atus to any suitable opening, and, after closing
all other inlets and outlets to the system,
forcing air into the system until there is a
uniform gage pressure of 5 pounds per square
inch or sufficient to balance a column of
mercury 10 inches in height. This pressure shall
be held without introduction of additional air
for a period of at least 15 minutes .
Sec. 28-1110. 2. Water Test. The water test
shall be applied to the drainage system either
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,
and the system filled with water to point of
overflow. 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 a 10-
foot head of water. In testing successive
sections , at least the upper 10 feet of the next
preceding section shall be tested, so that no
joint or pipe in the building (except 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 .

Sec. 28-1111. Test Required. Building sewers shall
be tested.
Sec. 28-1111. 1. Method. Test shall consist
of plugging end of building sewer at point of
connection with the public sewer and filling
the building sewer with water and testing with
not less than a 10-foot head of water.
Sec. 28-1112. Exhibitions . No test or inspection shall
be required where a plumbing system, or part thereof,
is set up for exhibition purposes and has no connection
with a water or drainage system.
Sec. 28-1113 . Water Supply System. Upon completion
of a section or of the entire water-supply system,
it shall be tested and proved tight under a water press-
ure not less than one hundred twenty-five (125) pounds .
The water used for tests shall be obtained from a
potable source of supply.
Sec. 28-1114. Leaders and Downspouts . Leaders or
downspouts and branches within a building shall be
tested by water or air in accordance with section
28-1110. 1 and 1110. 2.
Sec. 28-1115. Notice of Final Inspection. Upon the
satisfactory completion and final test of the plumbing
system a notice of final inspection, with the signature
of the plumbing inspector thereon, will be posted in a
suitable place in the building and a record of such
final inspection retained in the office of the building
official. A certificate of final approval shall be
issued to the owner upon request.
Sec. 28-1116. Test May Be Required. Wherever there
is reason to believe that the plumbing system of any
building has become defective, it shall be subjected
to test or inspection, and any defects found shall be
corrected as required in writing by the plumbing
inspector.
All installed plumbing systems and fixtures attached
thereto found defective or in any insanitary condition,
shall be repaired, renovated, replaced, or removed
within 10 days upon written notice from the plumbing
inspector. When defective plumbing is found to be
dangerous to the health of the occupants of a building
or to the patrons of a food establishment, the city
manager shall notify the health officer having juris-
diction, and said health officer shall take immediate
steps to protect the health of such occupants or
patrons . In the event the city manager is of the
opinion the defect found endangers the public water
supply, the defect shall be immediately corrected or
the plumbing system disconnected from the public water
supply.
