What is back-siphonage?

• When the pressure on the potable lines is decreased, and non-potable water is siphoned into the potable water supply

• A) At least equal to the diameter of the water supply inlet

• B) At least half the distance of the diameter of the water supply inlet

• C) At least twice the distance of the diameter of the water supply inlet

• D) No specific length is required

What is the purpose of an atmospheric vacuum breaker?

• A) To allow carbon dioxide to escape into the air during a backflow

• B) To prevent backflow in soda carbonation systems

• C) To prevent backflow caused by backpressure or back-siphonage in plumbing systems

• D) To erode the metal of water supply pipes

How does a double-vented check valve prevent backflow?

• A) By separating an inlet of potable water from a potentially contaminated source

• B) By preventing the mixture of carbon dioxide gas with water and syrup

• C) By allowing the carbon dioxide to escape into the air during a backflow

• D) By eroding the metal of water supply pipes
