A.
Where a public sanitary sewer is accessible in a street,
alley, easement or thoroughfare to a building or premises abutting
thereon, the liquid wastes from any plumbing system in said building
shall be discharged into the public sewer unless prohibited by some
law of New York State, Westchester County or Town of Mount Pleasant
ordinance or rule or regulation of a sewer district; provided, however,
that in the case of a building which has never been connected to a
public sanitary sewer, this section shall become effective 60 days
after a notice from the Inspector requiring such connection has been
mailed to the owner, addressed to the premises or to such other address
as may be recorded on the books of the Town of Mount Pleasant.
B.
Where the connection to the public sewer involves
a discontinuance of an existing cesspool or similar type of local
disposal unit, said unit shall be immediately disinfected in a manner
conforming to New York State Board of Health regulations and under
the direction and in the presence of the Inspector. The pit or pits
shall be covered over in a suitable and safe manner and at the end
of six months shall be filled with coal ashes or clean earth and left
safe in all respects.
C.
When existing plumbing work in a building is disconnected
from a private disposal unit and connected to a public sewer, a house
trap and fresh-air inlet shall be provided; the house drain shall
be replaced in part or entirely if found unsanitary; the direction
of flow of the main house drain, together with the house sewer, shall
not in any case have changes in direction aggregating greater than
90°.
Where the liquid wastes from any plumbing system
are not discharged into a public sewer, such wastes shall be treated
or disposed of in accordance with the rules and regulations of the
Westchester County Board of Health and a certificate of compliance
shall be filed with the Inspector before the final certificate of
inspection is issued by the Inspector. No building shall be occupied
before the final plumbing inspection certificate is issued by the
Inspector. All private sanitary disposal systems shall be kept in
good repair and shall be kept from overflowing or polluting the adjacent
area.
No rainwater, surface, subsurface and foundation
drainage disposal or water from condensing and cooling apparatus shall
be discharged into a public sanitary sewer. Such wastes may connect
with storm sewers where same are available. In cases of very small
amounts of water from cooling apparatus, the Inspector may allow a
variance from this rule; provided, however, that in all such cases
each outlet shall be provided with a cast-iron trap.
Corrosive or harmful wastes shall not be discharged
into a public sewer, nor shall such wastes be discharged into a plumbing
system to which water closets, bathtubs, lavatories or other household
plumbing fixtures are connected. The disposal system designed to receive
such wastes shall be of a material capable of resisting the destructive
action of such wastes, and the disposal method and system shall be
made to meet with the approval of the Inspector.
Water or other wastes heated to over 140°
F. shall not be discharged into a public sewer or into a plumbing
system to which water closets, bathtubs, lavatories or other household
plumbing fixtures are connected. The exhaust blowoff, sediment or
drip pipe from boilers or heating plants shall be of cast iron or
wrought iron galvanized and shall discharge into the top and above
the line of discharge of a suitable closed tank or condenser provided
with a relief pipe, of at least three inches in diameter, extending
to the outer air above the roof. The tank shall have a three-inch
minimum waste with 24 inches minimum seal trap and shall connect to
the house sewer. When blowoff tanks discharge water at a higher temperature
than herein permitted, they shall be provided with a cooling device
which shall reduce the temperature to less than 140° F. before
the same is discharged therefrom; provided, however, that where the
volume of such water is so small that, in the opinion of the Inspector,
it may be discharged safely into a sanitary sewer or sanitary disposal
system, the Inspector may issue a written permit therefor, revocable
on five days' notice.
[Amended 11-11-1980; 3-13-2001 by L.L. No. 1-2001]
No explosive or inflammable matters shall be discharged into any sewer or private sanitary disposal system. That portion of every building hereafter constructed or converted into a place of business where gasoline, benzine, naphtha or other inflammable oils or compounds are used shall be provided with catch basins and its own private disposal system located at least 15 feet from the property line and from any building on the lot on which such building is erected, unless gasoline and oil separator equipment approved by the Board of Fire Underwriters shall be installed and the drainage and vent system altered to conform, and shall not be connected with a sanitary sewer. A permit therefor shall be obtained from the Inspector before the installation thereof and an inspection fee as set forth in Chapter A224, Fees, paid to the Building Inspector before such permit is issued.
[Amended 11-11-1980; 3-13-2001 by L.L. No. 1-2001]
Catch basins and special sanitary disposal systems shall be installed in the drainage system from any yard, manure pit, stable or other like place, the discharge from which, if improperly treated, might become a nuisance or dangerous to the health of the community. No drains from any such areas nor any floor drains shall connect directly to a sanitary sewer or to a primary sanitary disposal system to which household fixtures are connected. A permit for such installation shall be obtained from the Inspector before the installation thereof and an inspection fee as set forth in in Chapter A224, Fees, paid to the Building Inspector before such permit is issued.
All horizontal piping shall be run in practical
alignment and at a uniform grade of not less than 1/4 inch per foot
up to four-inch diameter pipe, inclusive, and not less than 1/8 inch
per foot for all larger size pipe, and all piping shall be supported
or anchored at intervals not to exceed 10 feet. All stacks shall be
supported at their bases, and all pipes shall be rigidly secured.
All changes in direction shall be made by the
appropriate use of forty-five-degree Y's, long-sweep quarter bends
or sixth, eighth or sixteenth bends, except that sanitary T's may
be used on vertical stacks and short quarter bends may be used in
soil and waste lines where the changes in direction of flow are from
the horizontal to the vertical. T's and crosses may be used in vent
pipes.
No double-hub fitting or double the branch shall
be used on soil waste pipe lines. The drilling and tapping of house
drains, soil, waste or vent pipes and the use of saddle hubs and bands
are prohibited.
In the installation of any drainage system,
dead ends shall be avoided.
Offsets in the mains of all stacks shall be
avoided. However, they may be permitted in special cases as directed
by the Inspector and shall be made with deflection not greater than
45°.
A.
All freestanding stacks shall be thoroughly supported
on concrete or masonry piers or approved columns at their bases.
B.
Pipe supports, according to their location, shall
be made either with heavy iron posts or concrete or masonry piers,
provided that no brick pier shall be less than eight inches square.
Supports by the use of band iron are prohibited. Water and gas pipes
up to two inches inclusive may be hung from floor construction on
non-fireproof buildings. In fireproof buildings, approved hangers
may be substituted in place of piers.
All pipes passing under or through walls shall
be protected from breakage. All pipes passing through or under cinders,
cinder concrete or otherwise corrosive material shall be protected
against external corrosion after water test has been approved.
Workmanship shall be of such character as fully
to secure the results sought to be obtained in all of the sections
of this chapter.
