Air Break (Drainage System) Answer: A piping arrangement in which a drain from a fixture,
appliance or device discharges indirectly into another fixture, receptacle or interceptor at a point below
the flood level rim and above the trap seal.
Air Gap (Drainage System) Answer: The unobstructed vertical distance through the free atmosphere
between the outlet of the waste pipe and the flood level rim of the receptacle into which the waste pipe
is discharging. The distance between the waste pipe outlet and the flood level rim of the receptor must
be at least twice the diameter of the indirect waste pipe.
Air Gap (Water Distribution System) Answer: The unobstructed vertical distance through the free
atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing
fixture or other device and the flood level rim of the receptacle.
Appliance Answer: Any apparatus or device that utilizes a fuel or a raw material as a fuel to produce
light, heat, power, refrigeration or air conditioning that compresses fuel gases.
Backflow Answer: Pressure created by any means in the water distribution system, which by being
in excess of the pressure in the water supply mains causes a potential backflow condition.
Backsiphonage Answer: The backflow of potentially contaminated water into the potable water
system as a result of the pressure in the potable water system falling below atmospheric pressure of the
plumbing fixtures, pools, tanks or vats connected to the potable water distribution piping.
,Backflow Connection Answer: Any arrangement whereby backflow is possible.
Backflow Preventer Answer: A backflow prevention assembly, a backflow prevention device or
other means or method to prevent backflow into the potable water supply.
Bathroom Group Answer: A group of fixtures consisting of a water closet, lavatory, bathtub or
shower, including or excluding a bidet, an emergency floor drain or both. Such fixtures are located
together on the same floor level.
Branch Interval Answer: A vertical measurement of distance, 8 feet (2438 mm) or more in
developed length, between the connections of horizontal branches to a drainage stack. Measurements
are taken down the stack from the highest horizontal branch connection.
Branch Vent Answer: A vent connecting one or more individual vents with a vent stack or stack
vent.
Building Drain Answer: That part of the lowest piping of a drainage system that receives the
discharge from soil, waste and other drainage pipes inside and that extends 30 inches (762 mm) in
developed length of pipe beyond the exterior walls of the building and conveys the drainage to the
building sewer.
Code Answer: These regulations, subsequent amendments thereto or any emergency rules or
regulations that the administrative authority having jurisdiction has lawfully adopted
Combination Waste and Vent System Answer: A specially designed system of waste piping
embodying the horizontal wet venting of one or more sinks, lavatories, drinking fountains or floor drains

Pipe Material / Max Horizontal Bracing / Max Vertical Bracing Answer: ABS / 4ft / 10ft
Cast-Iron / 5ft / 15ft
, Copper Tubing (1 1/4 or smaller) / 6ft / 10ft
Copper Tubing (1 1/2 or larger) / 10ft / 10ft
PEX / 32in / 10ft

Contamination Answer: An impairment of the quality of the potable water that creates an actual
hazard to the public health through poisoning or the spread of disease by sewage, industrial fluids or

Cross Contamination Answer: Any physical connection or arrangement between two otherwise
separate piping systems, one of which contains portable water and the other, either water of unknown
or questionable safety or stream, gas or chemical, whereby their exists the possibility for flow from one
system to the other, with the direction of flow depending on the pressure differential between the two
systems ("Backflow").
Developed Length Answer: The length of a pipe measured along the center line of the pipe and
fittings.
Direct-Vent Appliances Answer: Appliances that are constructed and installed so that air from
combustion is derived directly from the outdoor atmosphere and all flu gases are discharged directly to
the outdoor atmosphere.
Fixture Drain Answer: The drain from the trap of a fixture to a junction with any other drain pipe
