SECTION 2. P�,RP,4ITS, Fr -ES AND PLANS.
a. Permit Required. Before commencing, repairing or installing of any
plumbing fixtures, the plumber doing the work must first obtain a written
permit from the plumbing inspector which shall give the location and
character of the work to be done, the number and kind of fixtures, and
the name of the owner or lessee of the premises wherein the proposed
work is to be done. In the meaning of this section, the word "repair"
shall not apply to ordinary repairs to water pipe, faucets, hot water
tanks, and water backs, or to the removal .)f obstructions in fixtures or
piping which are generally known and considered as maintenance work. It
is intended that replacement of fixtures .;here no new fixture is cut into
the system shall be considered as maintenance.
b. Fees for Permits. Before the issuance of any permit, the inspector shall
require the payment of a fee in accordance with the following table:
For plumbing systems containing; one to two fixtures,
the fee shall be fifty cents (500) for each and every
fixture with a minimum fee of one dollar ($1.00). For
each additional fixture, the fee shall be fifty cents '
(500) for all tixtures in excess of the first two. A
fee of two dollars and fifty cents (:12.50) shall be
charged for all sewer connections. The construction,
repair and maintenance of all sewer, drains, cesspools, etc.
whether public or private within the limits of the
City of Kalispell, shall be under the supervison of the
City Inspector, his authorized assistant or duly appoint
ad inspector. The fee shall cover location of wyes and
the establishing of grade for sewers. The contractor
shall furnish all necessary materials.
If alterations to the plumbing of an existing building
be desired, the permit fee shall be based upon the number
of fixtures affected or replaced. No fee shall be exacted
385
for work generally known as maintenance work. If any
work on the construction, alteration, er repairs of
a plumbing system be commenced without a permit hav-
ing first been secured, double the fees above stated
shall be exacted when a permit is finally issued. Pay-
ment of such double fees, however, shall in no way relieve
s,ich persons of the penalties imposed for violation of this;
code. If work under a permit be not commenced for six
months after its issuance, or if, after partial comple-
tion, the work is discontinued for a period of one (1)
year, the permit thereupon shall bec)me void and no work
shall be done at the premises until a new permit shall
have been secured.
c. Plumbing_ Fixtures Defined. For the purpose of fixing the amount
of inspection fees to be paid when issuing permits, each fixture
having a waste outlet, regardless of traps, shall be counted as a
fixture. Cellar drains, catch basins and cisterns connected with
the sewer shall be counted as fixtures.
d. Plane Required. ,accompanying the application for permit, there
shall be filed with the inspector plans of the work to be under-
taken, showing the number, character and location of all features
of the work, which plans shall also show the precise location of
the premises, the name of the owner, and shall be signed by the
plumbing contractor. Such plans shall be filed at least five days
in advance of commencement of the work contemplated, provided,
however, that no plans shall be required for plumbing work in
dwellings, dwellings houses of two floors or less. The permit is -
sited under this section shall not be held to allow the cutting of
any structural features of any building. There such necessity
arises, application shall be made to the plumbing inspector for
the necessary permit. The permit shall cover the work set forth in
the plans only and if additional work or changes in location of
' fixtures is to be undertaken, a new permit to cover such additional
work or modification shall be secured in the usual manner.

to the surface or grade of basement floor and tested with water or
air. Upon being found free from defective and leaking ,joints, the
tests shall be considered satisfactory. If a stable, garage or
any part thereof is used for human habitation or is so constructed
that it may be used as such, the same tests shall be made as for
an ordinary dwelling. Rain water leaders and their 'roof connections
where they are permitted within the,walls of any building and such
branches as connect with the house drain three feet beyond basement
wall shall be tested with water or air. No person shall place any

spector to the City of Kalispell upon whose receipt only shall such
additional inspection be made.
SECTION 4. HOUSE SEWER
Whenever practicable, every building shall have an independent con-
nection with a public sewer. Where a building stands in the rear of
another on the same lot or lots, the house drain from one building
may be extended to the other building and the whole will be con-
sidered as one house drain; provided however that the portion of the
house sewer not covered by a building with a concrete or masonry foun-
dation may be of vitrified pipe but the diameter of the conduit roust
not be reduced from the front building to the public sewer.
The house sewer shall be constructed of cast iron soil pipe or salt -
glazed Vitrified clay pipe. A permit shall first be obtained from
the plumbing inspector for the construction of the sewer. The fee for
this permit shall be two dollars and fifty cents ($2.50). Wherever
it is necessary to excavate'in any street or alley, a separate permit
' for this purpose roust be procured from the proper officials. Measure-
ments shall be obtained to locate the "Y" junctions in the public
sewer to which the house sewer shall connect. If such junction can-
not be found within three feet of the location given, a pert-iit shall
be granted to tap the sewer under the direction of the plumbing in-
spector.
Wherever it is possible, vitrified pipe shall be laid with a grade
of one-fourth inch, or more to the foot. In no case shall a grade of
less than one -eighth inch to the foot be used. The pipe shall be
laid uniformly to line and grade. Change in direction shall be made
with one -eighth bends except :;here the pipe can be laid upon a circle
with a radius exceeding 15 feet, in which case uniform deflection
may be made in each joint. No vitrified pipe shall be laid under any
building having- a concrete or masonry foundation, or within three
feet of same, t:nd iailenPver such a building is constructed over a vit-
rified pipe sewer or within three feet thereof, such sewer shall be
removed or relaid with soil pipe of equal inside diameter.
All vitrified pipe in the main house sewer shall have an internal
diameter of not less than four inches. Short branches may have such
diameter of four inches and be connected to the main house sewer
with "Y" junctions. Werever possible, the house sewer shall be laid
at such depth as to permit the house drain to enter the building be-
low the level of the basement or cellar floor. When deemed necessary
' by the inspector, for the purpose of inspection, no backfilling over
the pipe shall be done until permission is given by him.
SECTION 5. HOUSE, DRAIN
All house drains shall be made of cast iron pipe and shall not he
covered until inspected to determine that there are no leaks. Connec-

the type of ,system to be installed, and thti number and kind of radiators
to be used, the type of boiler and the name of the owner or lessee of
the premises wherein the proposed work is to be done. In the maning of
this section, the work "repair" shall not apply to ordinary repairs to
boilers, mains, .radiators, valves or traps, or to the removal of ob-
structions in equipment or.piping which are generally known and con-
sidered as maintenance work. It is intended that replacement of radia-
tors where no new radiator is cut into the system shall be considered
as main'tenance.
b. Fees -For Permits. Before the issuance of any permit, the inspector
shall require the payment of a fee in accordance with the following table
401.
For heating systems containing one to four radiators, the fee sla ll
be fifty cents (50¢) for each and every radiator with a minimum fee of
one dollar (91.00). For each additional radiator, the fee shall be
twenty-five cents (25d) for all radiators in excess of the first four.
If alterations to the heating of an existing building be desired the
permit fee shall be based upon the number of radiators affected or re-
placed. ho fee shall be exacted for work generally known as maintenance
work. If any work on the construction, alteration, or repairs of a heat-
ing system be commenced without a permit having first been secured, double
the fees above stated shall be exacted when a permit is finally issued.
Payment of such double fees, however, shall in no way relieve such per-
sons of the penalties imposed for violation of this code. If work under
a permit be not commenced for six months after its issuance, or if, after
partial completion. the work is discontinued for a period of one year,
the permit thereupon shall become void and no work shall be done at the
premises until a new permit shall have been secured.
c. Radiators defined. Radiator having a steam, vapor or water supply shall
be counted as a radiator. 3ach stock of indirect when used in a blast or
forced air system is also to be counted as one radiator.
d. Plans Required. Accompanying the application for permit, there shall
be filed with the inspector plans for the work to be undertaken, showing
the number, character and location of all features of the work, which
plans shall also show the precise location of the premises, the name of
the owner, and shall be signed by the heating contractor. Such plans shall
be filed at least five days in advance of commencement of the work con-
templated, provided, however, that no plans shall be ree_uired for le ating
work in dwellings, dwelling houses of two floors or less. The permit is-
sued under this section shall not be held to allow of the cutting d' any
structural features of any building. Where such necessity arises, applica-
tion shall be made to the plumbing inspector for the necessary permit.
The permit shall cover the work set forth in the plans only and if addi-
tional work or changes in location of radiators is to be undertaken, a
new permit to cover such additional work or modification shall be secured
' in the usual manner.
