[HISTORY: Adopted by the Commissioners (now Mayor and Council) of
the Town of Leonardtown by Ord. No. 27, effective 5-1-1964. Amendments noted
where applicable.]
All plumbing work performed within the corporate limits of the Town
of Leonardtown shall comply with state and county codes and with ordinances
now and hereafter issued and passed by the Commissioners of Leonardtown;[1] provided, however, in the event of conflict between such state
and county codes and said ordinances issued and passed by the Commissioners
of Leonardtown, the latter shall control and prevail.
[1]
Editor's Note: Pursuant to the 1989 Charter, the Commissioners of
Leonardtown are now the Mayor and Council of the Town of Leonardtown.
All plumbing work shall be performed under the supervision of a registered
master plumber.
Permits to do any of the following plumbing work shall be required,
and no such work shall be commenced until written permission is issued to
the plumber by the Commissioners of Leonardtown (hereinafter referred to as
the "Commissioners"):
A.
Installation of new interior plumbing.
B.
Additions, alterations or repairs and remodeling of or
to existing plumbing.
C.
Construction or reconstruction of water and sewer lines
from property lines to buildings.
D.
Installation of air conditioners, refrigeration equipment,
compressors, machinery and other devices and arrangements which use water
for cooling purposes.
E.
Construction of swimming pools, aquaria, baptistries
and similar structures.
A.
Separate water house connections and separate sewer house
connections for each separate lot or parcel of land abutting on a street,
alley or right-of-way in which there is a water main or sewer belonging to
the Commissioners will be constructed by the Commissioners from such water
main or sewer to the property line, as required. Charges for house connections
shall be made by the Commissioners.
B.
Water and sewer connections for properties not abutting
directly on a water main or sewer may be allowed under such conditions and
at such charges as the Commissioners may require.
C.
Separate connections.
(1)
The water or sewer service pipes for any building, lot,
premises or establishment shall not be laid over or through any other building,
lot, premises or establishment, except in an approved right-of-way or easement,
and no person shall connect or cause to be connected any building, lot, premises
or establishment with the water or sewer service pipe belonging to or supplying
any other building, lot, premises or establishment. However, this regulation
shall not prevent a dwelling with a private garage upon the rear of the same
lot or parcel of land from being supplied by the same service pipes; but if
the garage is converted wholly or partially into a dwelling or place of business,
a separate connection shall be installed under such conditions as the Commissioners
may require.
(2)
A single trailer located on a lot or parcel of land will
not be permitted to be connected to the water and sewer mains unless the trailer
installation is in compliance with all local, state and federal laws or regulations
governing the same. It will then be considered a single residence under these
plumbing regulations.
A.
Applications for permits for the above work shall be
submitted, in writing, by a registered master plumber for the premises involved,
upon forms supplied by the Commissioners. The applications shall be signed
in legible writing by the master plumber for the premises to be served. In
the case of organizations such as churches, schools, fraternal orders, clubs,
business corporations or partnerships, etc., the applications shall also be
signed by the name of the organization and the name of the person authorized
to conduct business for the organization.
B.
In addition to signing the applications for permits,
the owner is required to also sign, on the application form, an agreement
regarding the location of the curb cock as follows:
|
"In connection with this application I hereby agree that before the
water connection is installed to the property I will set a stake indicating
the elevation at which the top of the curb cock box should be set so that
it will conform to the finished grade.
| |
|
"I further agree that after the curb cock box is set in accordance therewith
I will reimburse the Commissioners for any expense to which it may be put
for later raising or lowering the box made necessary by reason of a subsequent
change in the grade or by failure to complete the grading as indicated by
the stakes.
| |
|
"I further agree that at such time as the Commissioners decide to install
water meters, I will permit such installation upon the property described
in this application, and I hereby authorize such installation, agree to pay
said Commissioners the cost of said meter and grant permission to the Commissioners,
their agents, servants or employees to enter upon the said property to install
and periodically read such meters."
|
C.
After the curb cock has been set by the Commissioners'
forces to the grade given, the owner will be required to sign a statement
that this is true.
D.
The master plumber who is to do the work covered by the
application for permit must himself sign said applications which shall be
filled in fully with the correct location of water and sewer lines, including
proof of depth and grade and measurements to existing reference points.
E.
The applications shall be accompanied by the payment
in full of the required charges and of the necessary inspection fees, such
payment to be made by the property owner.
A.
Two sets of plans in such detail as are necessary must
be submitted to the Commissioners when applications are made for a permit
for any plumbing work. One set of plans, approved with such corrections noted
as may be necessary to comply with the regulations, will be returned to the
plumber within 10 days. The plumbing system shall be installed in accordance
with such approved plans. No subsequent alterations shall be made in these
plans without the written approval of the Commissioners. The second set of
plans will be filed in the office of the Commissioners.
B.
Applications unaccompanied by the required plans will
be returned and will not be accepted until the plans have been presented.
C.
Permits will not be issued until the plans have been
approved.
A.
After the conditions outlined herein have been met, the
proper permit will be issued, and the work covered therein may then be performed
by the master plumber to whom it is issued, in accordance with these regulations.
The permit shall be kept on the job at all times and shall be shown upon demand
to the Plumbing Inspector.
B.
No work shall be started until proper permits have been
issued.
C.
An application is not a permit, and the submission of
an application does not confer permission to proceed with plumbing work.
A.
Applications for inside plumbing permits and for water
and/or sewer house connections will be accepted if the water main and/or sewer
are available to the property for which service is desired.
B.
When an application is made for an inside plumbing permit
and for a water connection to an existing water main and the sewer is not
available or cannot be made available, the applications shall show the method
of sewage disposal. If an existing individual private sewage disposal system
is proposed, the permit issued therefor by the County Health Department (or
other approving authority legally designated) shall be presented with the
application, and the record number of said permit shall be shown on the application.
This permit will be returned to the applicant.
[Amended 3-14-1994 by Ord.
No. 78]
Charges for water and sewer service, as set forth from time to time
by the Mayor and Council, must be paid by the applicant or owner before a
permit will be issued.
[Amended 3-14-1994 by Ord.
No. 78]
If, in the judgment of the Mayor and Council, it is necessary to tap a sewer house connection into an existing manhole, a charge as set forth from time to time by the Mayor and Council will be made in addition to the regular sewer house connection charge, and the installation shall be made in accordance with plans submitted to and approved by the Mayor and Council as set forth in § 107-8.
Work on private property, as the same is covered in this chapter, shall
be defined as all plumbing work performed on private property from the property
boundary line to a point three feet outside any building to be serviced by
the plumbing and shall include any repairs to existing plumbing.
The plumber, at the owner's expense and subject to the Commissioners'
inspection, shall construct the building water service and the building sewer
from the Commissioners' outlet at the property line to the building plumbing
system. No such connection shall be covered unless and until the Commissioners
or their duly appointed representatives shall inspect and approve such connections.
A.
The plumber shall not construct on private property any
underground work until the Commissioners have completed their water and sewer
house connections to the property lines, except as hereinafter provided. Inquiry
must be made at the Commissioners' office as to the location of the Commissioners'
water and sewer connections at the property line before any water or sewer
pipes are extended through building walls by the plumber. No change will be
made by the Commissioners in the proposed location of its water and sewer
connections if plumbers have installed pipes in such locations as will not
meet the Commissioners' connections. Any work performed contrary to this requirement
will be at the sole responsibility of the plumber making the installation,
and he will be required to remove and reinstall, at his own expense, any work
which cannot be properly connected to the Commissioners' pipes.
B.
Before a plumber may install work on private property
outside the building before the Commissioners' pipe has been installed in
the street, he shall require and receive, in writing, permission to do so.
As a condition precedent to such approval, the plumber shall agree, in writing,
that any misunderstanding arising as a result of this permission or any damage
occurring to the owner's pipe caused by the work of the Commissioners' in
the street will be the applicant's responsibility, and provided, further,
that after the connection between the Commissioners' and the applicant's pipe
has been made, said connection shall be inspected by the Commissioners.
A.
Alignment and slope.
(1)
Building water services and building sewers shall be
laid throughout to as straight an alignment as practicable. No part of a building
sewer shall be built without first determining the location of the end of
the sewer house connection and the beginning of the installed building drain.
(2)
On building sewers, changes in direction or slopes shall
be made by the use of approved fittings. On long building sewers, manholes
shall be used at approximately every 300 feet and at changes in direction
and slope or as directed. Manholes shall conform to standards required by
Commissioners.
(3)
Slopes of sewer lines shall be generally not less than
two feet in 100 feet. Before any sewer line is laid on a flatter slope than
two feet in 100 feet, written application shall be made and the Commissioners'
approval, in writing, obtained. No sewer line shall be laid at a slope of
less than one foot in 100 feet.
B.
Depth.
(1)
Building water service shall have a minimum of 3 1/2
feet of cover over the pipe and maximum of six feet of cover.
(2)
Building sewers shall have a minimum of two feet of cover
over the pipe, and this will be allowed only where a greater depth cannot
be obtained or where it is evident that the ground will be filled. Wherever
possible, building sewers shall be deep enough at their connection to the
building drain to drain any fixtures that may be located within the building,
but no deeper than necessary so to do.
A.
Sewer and water pipes shall be in separate trenches at
least seven feet apart, unless special permission, in writing, is secured
from the Commissioners.
B.
Laying pipes on private property.
(1)
Special care shall be taken to ensure that the pipes
are well bedded on a solid foundation and any defects due to settlement shall
be corrected by the plumber at his own expense. Bell holes, when required,
shall be dug sufficiently large to ensure the making of proper joints. Especial
precautions shall be exercised to prevent any pipe from resting on rock.
(2)
Proper and suitable tools and appliances for the laying
of pipe and fittings shall be used. Great care shall be taken to prevent the
pipe from being damaged. Pipe damaged in any way shall be repaired by the
plumber to the satisfaction of the Commissioners.
(3)
All pipe and fittings shall be thoroughly cleaned before
they are laid and shall be kept clean until the work is completed. At the
close of work each day, the end of the pipeline shall be tightly closed so
that no dirt or other substance shall enter the line. Upon completion of the
installation, the plumber shall disinfect the potable water system piping
in accordance with disinfection and sterilization procedures established by
the State Health Department.
(4)
Whenever pipe or fittings require cutting to fit the
line or to bring them to the required location, the work shall be done in
a workmanlike manner so as to leave a smooth end.
(5)
All sewers from the mains of the Commissioners to residences
and buildings to be served thereby shall be constructed of rootproof cast
iron soil pipe approved by the Commissioners.
No main running traps on building sewers will be allowed. All such existing
traps shall be removed, when so ordered.
Whenever a building sewer is found to be obstructed with tree roots
or is found broken or defective so that sewage escapes therefrom into the
surrounding soil or into adjacent premises, the Commissioners may order its
replacement or repair. In the event that the owner refuses or fails to make
such replacement or repair within 15 days after such notice, the Commissioners
will make the necessary corrections and will charge the owner the entire cost
of the work, which charge shall be a lien against the real estate upon which
such work is performed by the Commissioners.
A.
If a waterline on private property is found to be leaking,
it shall be the responsibility of the property owner to see that the leak
is repaired within three days. If the property owner fails to make such repairs,
the Commissioners, in order to conserve water, shall make such repairs as
are necessary and shall charge the owner for the costs of such work, which
charge shall be a lien against the real estate upon which such work is performed
by the Commissioners.
B.
Other outside water and sewer lines. All pertinent requirements
of this section shall apply to any water- and/or sewer lines on private property
laid outside of a building.
A.
Every building in which plumbing fixtures are installed
shall have fixture drains, vents, soil or waste stacks and building drains
of such materials and sizes and in such locations as are herein specified.
They shall be of extra heavy, medium or service weight cast iron, galvanized
wrought iron or steel, lead, brass or copper pipe, with caulked lead, screwed,
sweated or wiped joints. Soil and waste lines underground or under paved floors
shall not be of galvanized wrought iron or steel pipe.
B.
All drain, soil, waste, vent and water supply pipes above
ground shall be located inside of buildings, in a proper manner to protect
the same. In case a building has no cellar, water and sewer pipes shall be
securely protected from freezing in an approved enclosure where such pipes
rise from the ground to the floor of the building.
C.
No plumbing fixtures shall be set nor vertical soil,
waste, vent, water or gas pipes run in any vault, show window, bay window,
oriel or other projection beyond the building line.
D.
All soil, drain, waste, vent and supply pipes shall be
concentrated and run as directly as possible. They shall be protected from
exposure to frost and, wherever practicable, so located as to be accessible
for inspection. No such pipe shall be built into any masonry wall.
E.
Changes in direction of soil, drain, waste or vent pipes
shall not be more than 45º if possible and shall be accomplished by means
of Y-branches, sanitary tees, one-sixteenth, one-eighth or long sanitary bends.
The use of short pattern bends or tees is prohibited, except that quarter
bends may be used under water closet outlets.
F.
All soil, drain, waste, vent and supply pipes shall be
properly supported and fastened. All vertical soil or waste stacks shall be
properly supported upon a pier or other suitable foundation to prevent settlement.
When cast iron sewer, waste or vent lines are hung from ceilings or walls,
hangers or supports shall not be more than five feet apart.
G.
Dead ends shall be avoided in the installation of the
plumbing system.
H.
Openings in soil, vent, waste or water supply pipes shall
be closed by means of a suitable test plug, screw cap or other appropriate
fittings. No paper, wood, brick, plaster or other similarly unsuitable material
will be allowed. Plugs shall not be removed from pipe openings except during
the time the opening in the pipe is being actually used.
I.
Branch soil or waste pipes six inches or less in diameter
shall have a slope of 1/4 inch per foot. Vent pipes, where not vertical, shall
have a continuous slope in order to drain.
J.
Approved fittings shall be used for all connections in
soil, waste, vent and supply lines. No such line shall be trapped. Recessed
fittings shall be used on all waste lines.
K.
All laboratory waste and vent pipes shall be made of
approved chemical-resistant materials; such wastes shall discharge into a
diluting tank of required size before discharged into the Commissioners' sewerage
system.
L.
Whenever a pipe, joint, plumbing fixture or appurtenances
of a system of plumbing is broken, defective or inoperative, its repair or
replacement may be ordered by the Commissioners. Any order or notice issued
under the provisions of this section shall be promptly complied with by the
person responsible.
A.
Soil stacks shall not be less than four inches in diameter,
except that soil stacks of three inches in diameter will be allowed under
the following conditions:
(1)
Where the building within which such stack is placed
is not more than three stories, not including cellar or basement, in height
and where not more than four water closets shall be placed on any such stack,
with not more than two of the four water closets on any single floor.
(2)
Where the water closet connection is made to a four-inch
branch connected to the three-inch stack by a long sweep fitting or by an
approved four-inch-by-three-inch bend into an inch-long turn T-Y.
(3)
Where the stack shall connect to the sewer at the bottom
by a special sweep fitting increasing with the vertical.
B.
Soil stacks shall be run vertical throughout without
offsets or bends, if possible, and be of one size for its whole length, except
as hereinafter specified. Where offsets and bends have to be used, the layout
must be first approved by the Commissioners. They shall extend through the
roof, and no soil stack or vent pipe shall end less than 12 feet away from
all windows, doors and other air inlets.
A.
Wastes from the following shall not discharge directly
into any building drain, soil or waste pipe but shall discharge indirectly
to the building drainage system through an air gap into a receptor, which
shall serve the individual fixture device, appliance or apparatus:
(1)
Refrigerators, ice boxes, steam tables or other receptacles
or devices in which food or drink is stored.
(2)
Appliances, devices or apparatus used for the storage,
preparation or processing of food or drink.

The waste pipe of an indirect connection shall terminate one inch above
the floor level rim of a receptor consisting of an increaser fitting set in
a trap which shall be vented. The increaser fitting shall extend above the
floor so that it cannot be used as a floor drain and shall be in an accessible
location. An open accessible slop sink, properly trapped and vented, may be
used as a receptor for an indirect connection. A floor water closet or urinal
drain shall not be used as a receptor. The draining of a battery of cooking
kettles into a trough which has a floor drain fixture will be permitted.
A.
Refrigerator wastes:
(1)
Each refrigerator waste line shall be as short and direct
as possible and so arranged and fitted with a cleanout as to admit frequent
flushing.
(2)
Where refrigerator wastes from two or more floors discharge
into a single waste pipe, this pipe shall be not less than 1 1/2 inches in
diameter and shall extend through the roof as a vent. A refrigerator trap
shall be placed under each refrigerator.
(3)
Bar sinks, soda fountain sinks and laboratory sinks may
be directly connected to the drainage system, being properly trapped and vented,
or they may discharge indirectly as outlined above. For two-inch traps, the
vent may be four feet distant (developed length); for three-inch traps, six
feet; and for four-inch traps, eight feet. Drip pipes from not more than three
sinks or other waste receptacles may discharge into such a connection.
(4)

B.
Water-cooled air conditioning, refrigeration machinery
and compressor installations:
(1)
Rate of use of cooling water. All water-cooled air conditioning,
refrigeration machinery and compressor installations using water from the
public water supply for cooling purposes or discharging systems shall be installed
in accordance with these regulations and shall be subject to the Commissioners'
inspection and approval. A written permit will be required for each installation.
Such installation will be permitted to take water from the Commissioners'
system at a rate not greater than 0.08 gallon per minute per ton of refrigeration.
An approved type of economizer or cooling tower shall be installed if necessary
to meet this limitation.
(2)
Rating of water-cooled machinery. A ton of refrigeration
shall be considered as the cooling effect of 200 Btu's per minute. The standard
rating of refrigeration machines is expressed as the number of tons of refrigeration
it can produce under certain conditions. For compressors, one horsepower of
rated capacity will be considered equivalent to one ton of refrigeration.
(3)
Disposal of cooling water. Water from any such above
installations, whether or not the water is taken from the Commissioners' system,
shall not be discharged at a rate greater than 0.08 gallon per minute per
ton of refrigeration.
(4)
Cross-connection. All such installations shall be installed
with cross-connections and without the possibility of back-siphonage.

the sources of water supply and other pertinent data.
B.
All work performed shall comply with these regulations,
and the following minimum requirements shall be observed:
C.
No direct connection shall be made from a swimming pool
to the plumbing system of any building or to any storm drain, sanitary sewer,
cesspool, underground leaching pit or subsoil drain.
D.
If there are adequate means on the property for disposal
of the wastewater from a swimming pool, no connection to a storm drain or
sanitary sewer will be required.
E.
On indoor swimming pools, scum gutter drains and/or floor
drains serving the walks around the pool may be connected, if properly trapped,
to special waste pipes, provided that independent vent pipes are installed
on the high ends of the special waste mains in a manner that will assure a
circulation of air.
