that the work will stand the test prescribed before notifying the building official
that said work is ready for inspection.

system either in its entirety or in sections. If applied to the entire system, all
openings in the piping system 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

section under test, and each section shall be filled with water, but no section shall
be tested with less than a ten -foot (3m) head of water. In testing successive

be tested, so that no joint or pipe in the building (except the uppermost ten (10)
feet (3m) of the system) shall have been submitted to a test of less than a ten-
foot (3m) head of water. The water shall be kept in the system, or in the portion

apparatus 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 gauge pressure of
five (5) pounds per square inch (34.5kPa) or sufficient to balance a column of

required to permit inspection.
(6) Water Piping. Upon completion of a section or of the entire hot and cold
water supply system, it shall be tested and proved tight under a water pressure
test not less than the working pressure under which it is to be used. The water
used for test shall be obtained from a potable source of supply. A fifty (50)
pounds per square inch (344.5kPa) air pressure may be substituted for the water
test. In either method of test, the piping shall withstand the test without leaking
for a period of not less than fifteen (15) minutes.

violation of the provisions of this code or of the order or direction made pursuant
thereto.

shall be so constructed as to insure a positive mechanical seal and to remain closed,
except when discharging wastes. Such valves shall remain sufficiently open during
periods of low flows to avoid screening of solids and shall not restrict capacities or
cause excessive turbulence during peak loads. Unless otherwise listed, valve access
covers shall be bolted type with gasket and each valve shall bear the manufacturer's
name cast into body and cover. Backwater valves shall be installed so that their working
parts will be accessible for service and repairs.
Sec. 902. Materials.

(1) No galvanized steel pipe shall be used underground and shall be kept at
least six (6) inches aboveground.
(2) ABS and PVC DWV piping installations shall be limited to structures not
exceeding three (3) floors above grade. For the purpose of this Subsection, the
first floor of a building shall be that floor that has fifty percent (50 %) or more of
the exterior wall surface area level with or above finished grade. One (1)
additional level that is the first level and not designed for human habitation and
used only for vehicle parking, storage, or similar use shall be permitted.
(b) Vent piping underground shall be cast -iron soil pipe, copper tube type L or type
K, ABS or DWV schedule 40 plastic pipe.
(c) Vent fittings shall be cast -iron, galvanized malleable iron or galvanized steel,
lead, copper, brass, ABS or PVC schedule 40 or other approved materials except that
no galvanized malleable iron or galvanized steel fittings shall be used underground and
shall be kept at least six (6) inches aboveground.
(d) Changes in direction of vent piping shall be made by the appropriate use of
approved fittings and, with the exception of copper tube, no such pipe shall be strained
or bent. Burred ends shall be reamed to the full bore of the pipe.
Sec. 904. Vent Termination.
(a) Each vent pipe or stack shall extend through its flashing and shall terminate
vertically not less than six (6) inches above the roof nor less than one (1) foot from any
vertical surface.
