Questions and Answers Latest
2025/2026 GRADED A+
absolute pressure
- ANS - gauge pressure plus atmospheric pressure
it is measured in pounds per square inch absolute (psia) or in kilopascals
(kpaA)
air break
- ANS - the unobstructed vertical distance between the lowest point of of
an indirectly soil or waste pipe and the flood level rim of the fixture into
which it discharges
air gap
- ANS - the unobstructed vertical distance through air between the lowest
point of the water supply outlet and the flood level rim of the fixture or
device into which the outlet discharges
air space type vacuum breaker (ASVB)
- ANS - a manufactured device with a visible integral space between the
inlet and outlet of the fitting that prevents backflow
american water works association (AWWA)
- ANS - the international professional organization dedicated to the
,improvement of water quality and supply. it is an organization that sets
standards for the water industry.
approved testable backflow preventer
- ANS - a backflow preventer assembled as a unit with properly located
and approved shutoff valves and test cocks so the device can be
approved by a recognized testing agency as meeting material,
construction and operating requirements that are acceptable to the
authority having jurisdiction.
area protection
- ANS - backflow protection provided for a section of a piping system
with potable and non potable connections (that may or may not be
considered cross conections) downstream of a backflow preventer.
aspirator
- ANS - an apparatus for removing or ejecting liquids or gases using
suctions by means of the venturi effect. it can be used to mix liquids or
gases with water and is commonly used in dental offices
atmospheric pressure
- ANS - the pressure created by the weight of the atmosphere on a
surface. when elevation increases above sea level the atmospheric
pressure decreases the atmospheric pressure at sea level is 101 kpa (14.7
psi) or 10.3m (33.9feet) water column at sea level.
atmospheric vacuum breaker
- ANS - a vacuum breaker to designed to be under pressure only when
,water is being drawn from the water supply system and for short
intermediate periods of time
auxiliary water supply
- ANS - any water supply on or available to the premises other than the
primary potable water supply
backflow
- ANS - a flowing back or reversal of the normal direction of flow
backflow preventer
- ANS - a device or method that prevents backflow
backflow prevention device tester
- ANS - a person who has shown competence to test backflow prevention
devices and is certified in accordance with a canadian section of awwa.
sometimes referred to as a certified tester or ccc specialist.
back pressure
- ANS - a pressure higher than the supply pressure
Back siphonage
- ANS - backflow caused by pressure below atmospheric in the supply
system
barometric loop
- ANS - a fabricated loop of piping connected to the potable water supply
, that rises at least 10.7 meters (35 feet) at its uppermost point above the
highest fixture is serves. this type of backflow preventer protects against
back siphonage only
critical level (cl)
- ANS - the level of submergence at which a back siphonage preventer
ceases to prevent back siphonage
cross connection control program
- ANS - a program initiated by the authority having jurisdiction to
administer and regulate the selection installations testing and
maintenance of backflow preventers
differential pressure gauge
- ANS - the electronic or mechanical test equipment that measures the
difference in pressure between two points such as the high pressure side
and low pressure side of a check valve within a assembly
differential pressure relief valve
- ANS - one of the three main components of the reduces pressure
principle backflow assembly which is designed to open and discharge
water in the event either check valve should leak
double check detector assembly (dcda)
- ANS - a backflow preventer consisting of two approved double check
valves set in parallel equipped with a meter on the bypass line for the
purpose of detecting small amounts of water leakage or unauthorized
use. dcdas are designed to protect against back siphonage and back
pressure
