UPDATE!!!!2025/2026|GUARANTEED
A differential pressure gauge is used in testing of? - ANSWER Double check valve
assembly, and reduced Pressure principal assembly
Absolute pressure - ANSWER The total pressure exerted on a system, including
atmospheric pressure.
Air Gap seperation - ANSWER an unobstructed vertical distance throught he
atmosphere between the lowest opening from any pipe or faucet supplying water to a tank,
plubing, fixture or other device and flood level rim of the receptacle.
approved - ANSWER certified in writing by the director as a acceptable device or
methodology for the purpose of backflow prevention.
atmospheric pressure - ANSWER The pressure exerted by the atmosphere on all
objects within it 14.7 psi at sea level. As elevation increases, pressure decreases.
backflow - ANSWER means the undesirable reversal flow of water, or mixtures of
water and other liquids or gases into the distribution system.
back flow prevention assembly - ANSWER approved effective device or method used
to prevent backflow from occurring in the water supply which may be greater than the
pressure on the public water supply.
1
, Backpressure - ANSWER pressure on any source of water other than the public water
supply , which may be greater than the public water supply
back siphonage - ANSWER backflow due to negative pressure, pressure on the public
water supply may be reduced
bypass - ANSWER any arrangement of pipes, plumbing, or hoses designed to divert
the flow around an installed device through which the it normally flows.
containment - ANSWER preventing the impairment of the potable water supply by
installing an approved backflow prevention device at service connection. /when backflow is
installed down stream of the meter
protects city water!!
contamination - ANSWER presence of any foreign substance(organic, inorganic,
radiological, biological) in water that tends to degrade it quality so as to constitute a hazard.
continuous pressure - ANSWER condition in which upstream pressure is applied
continuously (more than 12 hours) to a device or fixture.
cross connection - ANSWER a physical connection between a potable water system
and a source of contamination
direct connection - ANSWER any arrangement of pipes, fixtures, or devices connecting
a potable water supply directly to a non potable source.
double check valve assembly - ANSWER device composed of 2 single independently
acting approved check valves, including tightly closing shutoff valves located at each end of
the device.
only approved for non health hazards
