					 non-conventional or non-prescriptive plumbing system [which requires special
					 approval from the state health officer prior to construction (see Chapter 12 of
					 this code)], each trap of each plumbing fixture does not contain an individual
					 vent. This system is different from battery venting in that it is not
					 necessarily constrained by all of the limits prescribed under the battery
					 venting requirements.

					 floor sinks, curbed cleaning facilities (with floor drain), hub drains, and
					 commercial dishwashing machines (used in restaurants, for example) are
					 considered
commercial

					 junction of two
fixture drains
and serving as a vent for both
					 fixtures.
Community Sewerage System
- any sewerage
					 system which serves multiple connections and consists of a collection and/or
					 pumping/transport system and sewage treatment facility.
Conductor
- see
leader
.
Continuous Vent -
a vertical vent that is
					 a continuation of the
drain
to which it connects.
Continuous Waste -
a
drain
from two or three fixtures connected to a single
trap
.
Critical Level -
the minimum elevation
					 above the
flood-level rim
of the fixture or receptacle served
					 at which a
backflow preventer
device may be installed. The
critical level
marking on a
backflow
preventer
device, including but not limited to a
vacuum breaker
, is normally a horizontal line usually stamped
					 on the device by the manufacturer, the location of which has been established
					 by the manufacturer to conform the device to an accepted standard with the goal
					 of having an approved installation of the device to ensure the proper
					 functioning of the device for cross connection control protection purposes.
					 When a
backflow
preventer
device does not
					 bear a
critical level
marking, the bottom of the
vacuum breaker
, combination valve or the bottom of any
					 approved
backflow preventer
device shall constitute the
critical level
.
Cross Connection -
any physical
					 connection or arrangement between two otherwise separate piping systems, one of
					 which contains
potable water
and the other, water of unknown
					 or questionable safety, whereby water may flow from one system to the other,
					 the direction of flow depending on the pressure differential between the two
					 systems. See
backflow
and
back-siphonage
.
Crown of Trap -
the topmost point of the
					 inside of a
trap's
outlet.
Dead End -

branch
leading from a
soil

developed
length
of 2 ft (610 mm) or more by means of a plug or other
					 closed fitting.
Depth of Water Seal -
the depth of water
					 which would have to be removed from a fully charged
trap
before air could pass through the
trap
.

associated with service to
					 mankind and the activities of his home or
private
residence,
					 the household, household affairs, the family, guest rooms of hotels and motels,
					 and patient rooms of hospital and nursing homes and guest rooms of similar
					 institutions. Water for and
liquid waste
from lavatories,
					 water closets, tubs and showers, kitchens, sinks, and home laundries are
					 considered domestic.
Double Offset -
two changes of direction
					 installed in succession or series in continuous pipe.
Downspout

Drain -
any waste pipe or soil pipe which
					 carries
waste
water or waterborne
wastes
in a

drainage system
.

water
					 outlet
at the point of water supply discharge or the minimum
					 cross-sectional area of the
liquid waste
outlet at the point
					 of
indirect waste pipe

					 terms of:
i. diameter of a circle; or,
ii. if the outlet is not circular, the diameter of a circle
					 of equivalent cross-sectional area.
b. This term is applicable to and mainly used when
					 determining the minimum unobstructed vertical distance through the free
					 atmosphere {
air gap (water distribution)
} required between the
water outlet
and the
flood rim level
of the
fixture
or receptacle into which it is discharging. This term
					 may also be applicable when determining the minimum unobstructed vertical
					 distance through the free atmosphere {
