A.
No pipe shall be laid so as to support any weight,
except fixtures, or be subjected to any strain whatsoever. All pipe
shall be properly laid and fastened to prevent becoming trapped and
shall be laid, when practicable, above timbers or beams instead of
beneath them. Where running lines or branches cross beams they must
do so within 36 inches of the ends of the beams, and in no case shall
said pipes be let into the beams more than two inches in depth. Any
pipe laid in a cold or damp place shall be properly dripped, protected
and painted with two coats of red lead and boiled oil or tarred.
B.
Where it is not impractical to do so, all risers shall
be left not more than five feet from the wall.
C.
No gas pipe shall be laid in cement or concrete unless
the pipe or channel in which it is placed is well covered with tar.
D.
When brass piping is used on the outside of plastering
or woodwork it shall be classed as fixtures.
A.
All fittings, except stopcocks or valves, shall be
of malleable iron.
B.
There shall be a heavy brass straightway cock or valve
on the service pipe immediately inside the front foundation wall.
Iron cocks or valves are not permitted.
C.
No unions or running threads shall be permitted. Where
necessary to cut out to repair leaks or make extensions, pipe shall
be put together with right and left couplings.
D.
All cast fittings, such as cock, swing joints, double
centers, nozzles, etc., shall be extra-heavy brass. The plugs of all
cocks must be ground to a smooth and true surface for their entire
length, be free from sand holes, have a bearing not less than 3/4
of an inch, except in cases of special design, have two flat sides
on the end of the washer and have two nuts instead of a tail screw.
All stop pins to keys or cocks shall be screwed into place.
A.
All drops must be set plumb and securely fastened,
each one having at least one solid strap. Drops and outlets less than
3/4 of an inch in diameter shall not be left more than one inch below
plastering, center pieces or woodwork.
B.
All outlets and risers shall be left capped until
covered by fixtures.
C.
Gas outlets for burners shall not be placed under
tanks, backs of doors or within four feet of any meter.
D.
Outlets for gas ranges shall have a diameter not less
than 3/4 inch, and all gas ranges and heaters shall have a straightway
cock on the service pipe.
A.
All gas brackets and fixtures shall be so placed that
the burners of the same are not less than three feet below any ceiling
or woodwork, unless the same is properly protected by a shield, in
which case the distance shall not be less than 18 inches.
(1)
No swinging or folding gas brackets shall be allowed.
(2)
No gas brackets on any lath and plaster partition
or woodwork shall be less than five inches in length, measured from
the burner to the plaster surface or woodwork.
(3)
Gas lights placed near window curtains or any other
combustible matter shall be protected by a proper shield.
B.
No gas fitter's cement shall be used, except in putting
fixtures together.
C.
All brass tubing used for arms and stems of fixtures
shall be at least No. 18 standard gauge and full size outside so as
to V cut a full thread.
D.
All threads on brass pipe shall screw in at least
5/16 of an inch. All rope or square tubing shall be brazed or soldered
into fittings and distributors or have a nipple brazed into the tubing.
After all piping is fitted and fastened and
all outlets are capped up there must be applied by the plumber, in
the presence of the Plumbing Inspector, a test with air to a pressure
equal to a column of mercury six inches in height, and the same shall
stand for five minutes. Only mercury gauge shall be used. No piping
shall be covered up, nor shall any fixture, gas heater or range be
connected thereto, until a card showing the approval of this test
has been issued by the Plumbing Inspector.
No meter will be set by any gas company until
a certificate is filed with it from the Village Clerk certifying that
the gas pipes and fixtures comply with the foregoing rules.
When for any reason it may be impractical to
comply strictly with the foregoing rules, the Plumbing Instructor
shall have the power to modify their provisions so that the spirit
and substance thereof shall be complied with. Such modification shall
be endorsed upon the permit over the signature of the Plumbing Inspector.
