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) Backflow Prevention Assembly Tester Training Exam 2024 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.
