Salmonellosis - ANS-A disease caused by pathogenic bacterica (often associated with
chicken), which affects the intestinal tract. The primary symptom is severe diarrhea.
A valve designed to open in the direction of normal flow and close with the reversal of
flow. - ANS-Check valve
Overflow level - ANS-The maximum height that water or liquid will rise in a receptacle
before it flows over the rim.
Backflow - ANS-A hydraulic condition, caused by a difference in pressures, in which
non-potable water or other fluids flow into a potable water system.
RPBP - ANS-A shortened name for a reduced pressure backflow preventer
Air Gap - ANS-In plumbing, the unobstructed vertical distance through the free
atmosphere between the lowest opening from any pipe or outlet supplying water to a
tank, plumbing fixture, or other container, and the overflow rim of that container
potential cross connection - ANS-Any arrangements of pipes, fittings, or devices that
indirectly connects a potable water supply to a non-potable source
Dysentery - ANS-A disease (sometime waterborne) caused by pathogenic
microorganisms and characterized by severe diarrhea with passage of mucus and blood
Backsiphonage - ANS-A backflow condition in which the pressure in the distribution
system is less than atmospheric pressure (subatmospheric)
Hose bib - ANS-A faucet to which a hose may be attached
Carrier - ANS-A human or animal that carries germs and can pass them to another
person without getting the disease himself.
, Reduced pressure zone backflow preventer - ANS-A mechanical device consisting of
two independnetly operating, spring-loaded check valves with a reduced pressure zone
between check valves.
Auxiliary supply - ANS-Any water source or system, other than the potable water supply,
that may be available in the building or premesis.
Actual Cross Connection - ANS-Any arrangement of pipes, fittings, that connects a
potable water supply directly to a non-potable source at all times.

are jaundice, general weakness, nausea, and the presence of dark urine.
Feed water - ANS-Water that is added to a commercial or industrial system and
subsequently used by the system, such as water that is fed to a boiler to produce
steam.
Pressure vacuum breaker - ANS-A device designed to prevent backsiphonsge,
consisting of one independently operating spring-loaded check valve and an
independently operating spring-loaded air-inlet valve.
Bypass - ANS-In cross-connection control, any pipe arrangement that passes water
around a protective device, causing it to be ineffective.
Gastroenteritis - ANS-An intestinal disease caused by pathogenic microorganisms,
which involves inflammation of the stomach and intestines. Symptoms are diarrhea,
pain, and nausea.
Back pressure - ANS-A backflow condition in which a pump, elevated tank, boiler or
other means results in a downstream pressure greater than the supply pressure
Incubation period - ANS-The time period that elapses between the time a person is
exposed to some disease and the time that person shows the first sign of symptom of
the disease.
Cross connection - ANS-Any arrangement of pipes, fitting, fixtures, or devices that
connects a non potable system to a potable water system
Atmospheric vacuum breaker - ANS-A mechanical device consisting of a float check
valve and an air inlet port designed to prevent backsiphonage
