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 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.

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 not less than 3/4 of an inch
bearing, except in cases of special design, have two flat sides on
the end of 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

plastering, centerpieces 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, back of doors or within four feet of any meter.
A.
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 Building Inspector, a test with air to a pressure equal to
a column of mercury six inches in height, and the same to stand for
five minutes. Only mercury gauge shall be used.
B.
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 Building 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.
