Questions and Answers
  • 1. 

    The physical separation between a waste pipe and an indirect receptor or device indirectly connected.

    • A.

      Air break

    • B.

      Air gap

    • C.

      Angle valve

    • D.

      Backflow

    Correct Answer
    A. Air break
    Explanation
    An air break refers to the physical separation between a waste pipe and an indirect receptor or device that is indirectly connected. This separation ensures that there is a gap of air between the waste pipe and the receptor, preventing any backflow or contamination from occurring. It acts as a protective barrier to maintain the integrity and safety of the plumbing system.

    Rate this question:

  • 2. 

    The unobstructed vertical distance through the free atmosphere between the outlet of a faucet and the flood level rim of the fixture or receptacle.

    • A.

      Air break

    • B.

      Air gap

    • C.

      Angle valve

    • D.

      Backflow

    Correct Answer
    B. Air gap
    Explanation
    An air gap refers to the unobstructed vertical distance between the outlet of a faucet and the flood level rim of the fixture or receptacle. It is a physical separation that prevents backflow, which is the undesirable reversal of the flow of water or other substances. The air gap ensures that there is no direct connection between the water supply and potentially contaminated water, thus protecting the water supply from contamination.

    Rate this question:

  • 3. 

    A valve in which the inlet and outlet openings are at 90 degree angle to one another.

    • A.

      Air break

    • B.

      Air gap

    • C.

      Angle valve

    • D.

      Backflow

    Correct Answer
    C. Angle valve
    Explanation
    An angle valve is a type of valve that has the inlet and outlet openings positioned at a 90-degree angle to each other. This design allows for easy installation in tight spaces or areas where pipes need to change direction. Angle valves are commonly used in plumbing systems to control the flow of water or other fluids.

    Rate this question:

  • 4. 

    The flow of water or waste water in pipes in reverse direction from that normally intended.

    • A.

      Air break

    • B.

      Air gap

    • C.

      Angle valve

    • D.

      Backflow

    Correct Answer
    D. Backflow
    Explanation
    Backflow refers to the flow of water or waste water in pipes in the opposite direction from what is intended. This can occur when there is a change in pressure within the plumbing system, causing the water to flow back into the supply lines. Backflow can be a serious issue as it can contaminate the clean water supply with pollutants or bacteria from the wastewater. To prevent backflow, devices such as backflow preventers are installed in plumbing systems to ensure that water only flows in the intended direction.

    Rate this question:

  • 5. 

    A pressure within the sanitary drainage system or vent piping system that is greater than the atmospheric pressure (>14.7psi)

    • A.

      Back pressure

    • B.

      Back siphonage

    • C.

      Backwater valve

    • D.

      Ball valve

    Correct Answer
    A. Back pressure
    Explanation
    Back pressure refers to a situation where the pressure within the sanitary drainage system or vent piping system exceeds the atmospheric pressure. This can occur when there is a blockage or restriction in the system, causing the pressure to build up. Back pressure can lead to various issues such as leaks, bursts, or even damage to the system. It is important to address and fix any back pressure problems to ensure the proper functioning of the drainage system.

    Rate this question:

  • 6. 

    The flowing by the negative pressure of contaminated or polluted water from a plumbing fixture into a potable water system.

    • A.

      Back pressure

    • B.

      Back siphonage

    • C.

      Backwater valve

    • D.

      Ball valve

    Correct Answer
    B. Back siphonage
    Explanation
    Back siphonage refers to the flow of contaminated or polluted water from a plumbing fixture into a potable water system. This can occur when there is a negative pressure in the system, causing the water to flow backwards. Back siphonage can contaminate the drinking water supply, making it unsafe for consumption. To prevent back siphonage, backflow prevention devices such as backwater valves are used to ensure that water only flows in one direction. A ball valve is a type of valve that controls the flow of water by using a ball to open or close the passageway.

    Rate this question:

  • 7. 

    A device installed in piping to prevent the reverse flow of storm or sewage into the drainage system or their branches.

    • A.

      Back pressure

    • B.

      Back siphonage

    • C.

      Backwater valve

    • D.

      Ball valve

    Correct Answer
    C. Backwater valve
    Explanation
    A backwater valve is a device installed in piping to prevent the reverse flow of storm or sewage into the drainage system or their branches. It acts as a one-way gate, allowing the flow of wastewater out of the system but preventing any backflow from entering. This is important to prevent contamination and flooding in the drainage system, especially during heavy rainfall or flooding events.
