<br />ARTICLE I—ADMINISTRATION.
<br />22.1-1. Basic Principles.
<br />The basic principles of this Code are enunciated as basic
<br />-oals in environmental sanitation worthy of accomplishment
<br />through properly designed, acceptably installed, and ade uate-
<br />IY maintained plumbing system. Some of the details of lum -
<br />ing construction must vary, but the basic sanitary andsb
<br />safety
<br />principles are the same. The results desired and necessary to
<br />protect the health of the people are the same everywhere.
<br />While the following principles are not Code requirements
<br />unforeseen situations arise, which are not covered in the body
<br />of the Code, such as

<br />(b) Definition of Terms—
<br />AIR GAP. An air gap in a water supply system is the un-
<br />obstructed vertical distance through the free atmosphere be-
<br />tween the lowest opening from any pipe or faucet supplying
<br />water to a tank, plumbing fixture, or other device and the
<br />flood -level rim of the receptable.
<br />ANCHORS. See SUPPORTS.
<br />APPROVED. Approved means accepted or acceptable un-
<br />der an applicable specification stated or cited in this Code, or
<br />accepted as suitable for the proposed use under procedures and
<br />powers by the Plumbing Board.
<br />AREA DRAIN. An area drain is a receptacle designed to
<br />collect surface or rain water from an open area.
<br />BACKFLOW. Backflow is the flow of water or other liquids,
<br />mixtures, or substances into the distributing pipes of a potable
<br />supply of water from any source or sources other than its in-
<br />tended source. (See BACK -SIPHONAGE.)
<br />BACKFLOW CONNECTION. Backflow connection or con-
<br />dition is any arrangement whereby backflow can occur.
<br />BACKFLOW PREVENTER. A backflow preventer is a de-
<br />vice or means to prevent backflow into the potable water sys-
<br />tem.
<br />BACK -SIPHONAGE. Rick-sinhonaoe is the flowing back of
<br />used, contaminated, or polluted water from a plumbing fixture
<br />or vessel into a water supply pipe due to a negative pressure in
<br />such pipe. See BACKFLOW.
<br />BATTERY OF FIXTURES. A "battery of fixtures" is any
<br />group of two or more similar adjacent fixtures which dis-
<br />charge into a common horizontal waste or soil branch.
<br />BOILER BLOW -OFF. A boiler blow -off is an outlet on a
<br />boiler to permit emptying or discharge of sediment.
<br />BRANCH. A branch is any part of the piping system other
<br />than a main, riser or stack.
<br />BRANCH HORIZONTAL. See HORIZONTAL BRANCH.
<br />BRANCH FIXTURE. See FIXTURE BRANCH.
<br />BRANCH INTERVAL. A branch interval is a length of
<br />soil or waste stack corresponding in general to a story height,
<br />flow depending on the pressure differential between the two
<br />systems. (SEE BACKFLOW AND BACK -SIPHONAGE.)
<br />DEAD END. A dead end is a branch leading from a soil,
<br />waste, or vent pipe, building drain, or building sewer, which
<br />is terminated at a developed distance of 2 feet or more by
<br />means of a plug or other closed fitting.
<br />DEVELOPED LENGTH. The developed length of a pipe is
<br />the length along the center line of the pipe and fittings.
<br />DIAMETER. Unless specifically stated, the term "diameter"
<br />is the nominal diameter as designated commercially.
<br />DOUBLE OFFSET. A double offset is two changes of di-
<br />rection installed in succession or series in continuous pipe.
<br />DOWNSPOUT. See LEADER.
<br />DRAIN. A drain is any pipe which carries waste water or
<br />water borne wastes in a building drainage system.
<br />DRAINAGE PIPING. See DRAINAGE SYSTEM.
<br />DRAINAGE SYSTEM. A drainage system (drainage pip-
<br />ing) includes all the piping within public or private premises,
<br />which conveys sewage, rain. water, or other liquid wastes to a
<br />legal point of disposal, but does not include the mains of a
<br />public sewer system.
<br />DUAL VENT. See COMMON VENT.
<br />DURHAM SYSTEM. Durham system is a term used to de-
<br />scribe soil or waste systems where all piping is of threaded
<br />pipe, tubing, or other such rigid construction, using recessed
<br />drainage fittings to correspond to the types of piping.
<br />•
<br />r�
<br />•
<br />EFFECTIVE OPENING. The effective opening is the min-
<br />imum cross-sectional area at the point of water -supply dis-
<br />charge, measured or expressed in terms of (1) diameter of a
<br />circle, (2) if the opening is not circular, the diameter of a
<br />circle of equivalent cross-sectional area. (This is applicable to •
<br />air gap.)
<br />EXISTING WORK. Existing work is plumbing which has
<br />been installed or approved for installation prior to the effective
<br />date of this Code.
<br />FIRM. See CONTRACTLNG FIRM.
