Responsibility - 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 the inspection is requested.
Media
-The piping of the plumbing, drainage and venting systems shall be tested with
water or air. The Administration Authority may require the removal of any
cleanouts, etc., to ascertain if the pressure has reached all parts of the
system. After the plumbing fixtures have been set and their traps filled with
water, they shall be submitted to a final test.
Water test
-The water test shall be applied to the drainage and vent systems 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 a 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 ten (10) foot (3m) head of water. In
testing successive sections, at least the upper ten (10) feet (3m) of the next
proceeding section shall be tested, so that no joint or pipe in the building
(except the uppermost ten (10) foot (3m) of the system) shall have been
submitted to a test of less then a ten.(10) foot (3m) head of water. The water
shall be kept in the system, or the portion under test, for at east fifteen
(15) minutes before inspection starts. The system shall then be tight at all
points.
Air test
-The air test shall be made by attaching an air compressor testing 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 gage pressure of
five (5) pounds per square inch (34.5 kPa) or sufficient to balance a column
of mercury ten (10) inches (254mm) in height. The pressure shall be held
without introduction of additional air for a period of at least fifteen (15)
minutes.
Building
sewer test -Building sewers shall be tested
by plugging the end of the building sewer at its point of connection with the
public sewer or private sewer disposal system and completely filling the
building sewer with water from the lowest to the highest point thereof, or by
approved equivalent low pressure air test, or by another test as may be
prescribed by the Administration Authority. The building sewer shall be
watertight at all points.
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 not less than the working pressure in which it is
to be used. The water used for tests shall be obtained from a potable source
of supply. A fifty (50) pound per square inch (344.5 kPa) 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.
