Answers
\.Access (to) - Answer- That which enables a fixture, appliance or equipment to be reached
by ready access or by a means that first requires the removal or movement of a panel, door or
similar obstruction.
\.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 by means of a common waste and vent pipe adequately sized to provide free
movement of air above the flow line of the drain.
\.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
PVC / 4ft / 10ft
\.Common Vent - Answer- A vent connecting at the junction of two fixture drains or to a
fixture branch and serving as a vent for both fixtures.
\.Conductor - Answer- A pipe inside the building that conveys stormwater from the roof to a
storm or combined building drain.
\.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 waste.
\.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").
