in a dwelling and accessory buildings located on
the same lot or premises. and which such
accessory building does not contain sleeping
quarters, or house more than two passenger-
carrying automobiles: provided, that such
plumbing is installed at the same time as the
plumbing with the accompanying dwelling.
Exception: No permit shall be required in the
following cases:
1. The stopping of leaks or the repair of
defects in any plumbing, provided no new
materials are used;
2. The repair of a water heater other than its
vents, provided the water heater is not
disconnected;

and bath tubs, provided approved type
faucets are used and are properly installed;
6. The replacement of an electric water
heater, providing the rough plumbing is not
altered;
7. Any gas piping not more than six feet in
length between an approved gas outlet and
any gas-fired appliance, provided that any
such gas fired appliance is in the same room
as the gas outlet.
INSPECTIONS REQUIRED
Concealing of work.
No person shall fail, neglect or refuse to leave
and keep any plumbing, as regulated by this
chapter, open, uncovered and convenient for
inspection until such plumbing has been
inspected and approved by the building official or
an authorized plumbing inspector, and any
obstruction whatsoever, which interferes with a
complete and thorough inspection of any
plumbing, shall be removed upon notice so to do,
and shall be left and kept removed until such
plumbing has been inspected and approved.
DRAINAGE AND VENTS
Under slab or underground drainage and vent
piping within a dwelling must be cast iron soil
pipe, approved plastic or type "DWV" copper
tube. Drainage and vent piping installed more
than 6 inches above ground or concrete may be
galvanized steel pipe.
Drainage piping must slope or grade at least 1/4
inch per foot. Plumbing fixtures must be an approved type and
must be properly trapped and vented.

Clean-outs shall be provided at horizontal
changes of direction, and at the upper end of the
building drain.

WATER PIPING
Galvanized steel water piping shall not be
installed in the ground under a building, unless it
is protected against corrosion by a machine
applied coating or wrapping.
Copper tubing type L or heavier may be used in
all locations. All joints installed below the floor
slab shall be brazed.
Copper tubing type M or heavier, may be used in
the ground outside and within the building walls
and attic.
The size of each section of water piping system
is determined from a combination of:
1. The minimum pressure available in the
main.
2. The elevation of the highest outlet.
3. The distance to the most remote outlet.
4. The number of outlets supplied.
5. Exterior and interior hose water faucets
and laundry sink type water faucets shall be
protected by an approved non-removable
type back-flow prevention device.
GAS PIPING
Gas piping may not be installed underneath the
raised floor of a building when the gas line is in
the ground or under/within a concrete floor slab
of a building. The gas pipe can be attached to
the raised wood floor joists a minimum of 6
inches above grade.
Gas Piping shall not be installed in the ground
unless it is protected against corrosion by a
machine applied coating or wrapping
Unions for gas pipe are only permitted at an
exposed fixture appliance or equipment
connection and in exposed exterior locations
immediately on the discharge side of a appliance
shut off valve.
The size of each section of gas piping system is
determined by the distance from the meter to the
most remote outlet plus the gas demand of the
appliances served.
Once all gas pipe has been installed, perform an
air pressure test on the new gas system. The air
test shall be made by attaching an air
compressor testing apparatus to any suitable
opening, and, after closing all inlets and outlets
to the system, forcing air into the system until
there is a uniform gauge pressure of 10 pounds
per square inch. The pressure shall be held
without induction of additional air for a period of
15 minutes.
TESTING AND INSPECTION
All work must be inspected and approved before
being covered, concealed, or put into use. All
tests must be witnessed by the inspector.

Building sewers shall be tested by plugging the
end of the building sewer at its point of
connection with the public sewer and completely
filling the building sewer with water from the
lowest to the highest point.

Drainage, and vent systems must be tested by
filling with water and must be watertight. No
section shall be tested with less than a ten (10)
foot head of water.

Water piping must withstand the street main
pressure or 50 p.s.i of air pressure without
leaking.

Metallic gas piping must withstand 10 p.s.i. air
pressure for at least 15 minutes without leaking.
