Salmonellosis - ANSWER: 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. - ANSWER: Check valve
Overflow level - ANSWER: The maximum height that water or liquid will rise in a
receptacle before it flows over the rim.
Backflow - ANSWER: A hydraulic condition, caused by a difference in pressures, in
which non-potable water or other fluids flow into a potable water system.
RPBP - ANSWER: A shortened name for a reduced pressure backflow preventer
Air Gap - ANSWER: 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 - ANSWER: Any arrangements of pipes, fittings, or devices
that indirectly connects a potable water supply to a non-potable source
Dysentery - ANSWER: A disease (sometime waterborne) caused by pathogenic
microorganisms and characterized by severe diarrhea with passage of mucus and
blood
Backsiphonage - ANSWER: A backflow condition in which the pressure in the
distribution system is less than atmospheric pressure (subatmospheric)
Hose bib - ANSWER: A faucet to which a hose may be attached
Carrier - ANSWER: A human or animal that carries germs and can pass them to
another person without getting the disease himself.
Reduced pressure zone backflow preventer - ANSWER: A mechanical device
consisting of two independnetly operating, spring-loaded check valves with a
reduced pressure zone between check valves.
Auxiliary supply - ANSWER: Any water source or system, other than the potable
water supply, that may be available in the building or premesis.
, Actual Cross Connection - ANSWER: Any arrangement of pipes, fittings, that connects
a potable water supply directly to a non-potable source at all times.
Hepatitis - ANSWER: An inflammation of the liver caused by a pathogenic virus.
Symptoms are jaundice, general weakness, nausea, and the presence of dark urine.
Feed water - ANSWER: 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 - ANSWER: 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 - ANSWER: In cross-connection control, any pipe arrangement that passes
water around a protective device, causing it to be ineffective.
Gastroenteritis - ANSWER: An intestinal disease caused by pathogenic
microorganisms, which involves inflammation of the stomach and intestines.
Symptoms are diarrhea, pain, and nausea.
Back pressure - ANSWER: 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 - ANSWER: 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 - ANSWER: Any arrangement of pipes, fitting, fixtures, or devices
that connects a non potable system to a potable water system
Atmospheric vacuum breaker - ANSWER: A mechanical device consisting of a float
check valve and an air inlet port designed to prevent backsiphonage
Double Check Valve Assembly - ANSWER: A testable mechanical device consiting of
two independently operating, spring-loaded check valves
Potable - ANSWER: Water that is safe for human consumption
Backflow - ANSWER: The reversal of the normal direction of flow
Backpressure - ANSWER: An elevation of pressure in the downstream piping system
above the supply pressure
