    It is installed outside the foundation wall of the building.

    • Overhead Storm Drain

    • Outside Storm Drain

    • Splash Pan

    • Inside Storm Drain

    Correct Answer
    A. Outside Storm Drain
    Explanation
    An outside storm drain is installed outside the foundation wall of a building. This type of storm drain is designed to collect and divert rainwater and other runoff away from the building's foundation to prevent water damage and flooding. By being positioned outside the foundation wall, it ensures that any excess water is directed away from the building, reducing the risk of water infiltration and structural issues.

    Storm Drain is installed provided a slope of NOT MORE THAN ______ PER METER RUN.

    • 0.5 %

    • 1 %

    • 1.5 %

    • 2 %

    Correct Answer
    A. 2 %
    Explanation
    Storm Drain is installed provided a slope of NOT MORE THAN 2% PER METER RUN. This means that the maximum slope allowed for the installation of a storm drain is 2% per meter of distance. A slope of 2% means that for every meter of horizontal distance, the vertical distance will increase by 2 centimeters. This slope is necessary to ensure proper drainage and prevent water from pooling or stagnating in the drain. A steeper slope would cause the water to flow too quickly, potentially causing erosion or other issues.

    Explanation
    A roof leader is a term commonly used to refer to a water conductor or downspout. It is responsible for collecting rainwater from the roof and directing it away from the building. The term "roof leader" is often used in the context of drainage systems and is widely recognized in the construction and plumbing industries.

    Rate this question:

  • 49. 

    The House Drain should be sized correctly to have a flow of about ___ of the pipe diameter.

    • 45%

    • 50%

    • 55%

    • 60%

    Correct Answer
    A. 50%
    Explanation
    The House Drain should be sized correctly to have a flow of about 50% of the pipe diameter. This means that the diameter of the drain should be approximately half of the diameter of the pipe it is connected to. This sizing ensures that the drain can effectively handle the flow of wastewater and prevent any blockages or backups. A larger drain diameter would result in inefficient flow, while a smaller diameter would increase the risk of clogs. Therefore, a 50% flow rate is optimal for the House Drain.
