In the installation of the house connections
to the house sewer laterals, the following standards are hereby established
as to the pipe to be used.
Connections made to one- or two-family dwellings
shall use 45 pounds per length (five feet), medium-weight cast-iron
pipe of the best quality, or 60 pounds per length (five feet), extra-heavy-weight
cast-iron pipe of the best quality, no less than four inches in diameter,
or Class 3300 asbestos cement pipe.
House connections made to buildings other than
one- or two-family dwellings shall use 60 pounds per length (five
feet), extra-heavy-weight cast-iron pipe of the best quality, no less
than four inches in diameter, or Class 3300 Transite.
In the event that the existing house drain to
which the house connection is to be connected is larger than four
inches in diameter, then in such event the pipe to be used in making
such house connection must be of such larger size for its entire length.
Extra-heavy-weight cast-iron pipe or its equivalent
in asbestos cement pipe rather than medium-weight cast-iron pipe as
herein permitted shall be used in the installation of any house connection
under driveways, under filled areas or in any other area as may be
directed by the Plumbing Inspector, whose decision thereon shall be
final.
The use of medium-weight cast-iron pipe in installations
made to one- and two-family dwellings as herein permitted shall apply
only to house connections made to the public sanitary sewer and shall
not apply to connections made to private sewage disposal systems,
which shall still require the use of extra-heavy-weight cast-iron
pipe or equivalent asbestos cement pipe.
All pipes used in the installation of house
connections shall be laid on a smooth bottom, with a special groove
cut in the bottom of the trench for each hub (in order to give the
pipe a solid bearing throughout its entire length). The soil shall
be well rammed on each side of the pipe. Such pipe shall be laid with
the joints properly caulked with lead, or with rubber rings for asbestos
cement pipe properly joined. The spigot end and hub ends shall be
concentric.
All pipe used in the installation of house connections
shall be so installed that the legend imprinted thereon indicating
the weight of such pipe may be seen from above and shall be exposed
for its entire length for examination and approval of the Plumbing
Inspector.
