AND ANSWERS TEST BANK GRADED A+
VERIFIED SOLUTIONS
●● Approve backflow present prevention assembly.
Answer: An assembling that has been evaluated/tested and approved
according to the authority having jurisdiction for use within their water
system
●● Aspirator effect.
Answer: The hydraulic effect of suction created by aspirator or
restricting area flow at this restricted area of flow. The pressure drops a
sub atmospheric creating suction.
●● Atmospheric vacuum breaker (AVB).
Answer: A non-touchable backflow device that consists of a body a
check valve member and an atmospheric opening. An AVP protects
against back softening only not back pressure
●● Auxiliary water supply.
Answer: Any water supplying on or available to the premises, other than
water supplied by the public water provider
, ●● Backflow.
Answer: The undesirable reversible of flow of contaminated water, other
liquids or gases into the distributor system of a potable water supply
●● Back pressure.
Answer: The hydraulic condition of increased pressure in a system
above supply pressure which results in a backflow into a portable water
supply
●● Backsiphonage.
Answer: The hydraulic condition, resulting in a backflow due to a
reduction in system pressure which causes a sub atmospheric pressure to
exist in the water supply
●● Bypass.
Answer: Any arrangement of pipes, plumbing or hoses designed to
divert the flow around and installed backflow device or assembly
through which the flow normally passes
●● Check valve.
Answer: The mechanical device designed to allow flow in One Direction
only
●● Containment.
