    • 1%

    • 2%

    • 3%

    • 4%

    Correct Answer
    A. 2%
    Explanation
    The typical slope of a waste pipe is 2%. This means that for every 100 units of horizontal distance, the waste pipe will have a vertical drop of 2 units. This slope is necessary to ensure that waste and water flow efficiently through the pipe, preventing clogs and backups. A steeper slope could cause excessive water velocity and potential damage to the pipe, while a shallower slope could result in sluggish flow and accumulation of waste. Therefore, a 2% slope strikes a balance between efficient drainage and pipe integrity.

    What should not be permitted to cross a beam?

    • Soil pipe

    • Electrical wiring

    • Water pipe

    • AC ducts

    Correct Answer
    A. Soil pipe
    Explanation
    Soil pipes should not be permitted to cross a beam because they can cause structural issues. Soil pipes are used for waste disposal and can carry heavy loads of water and waste. Crossing a beam can put excessive weight on the beam and potentially cause it to weaken or fail. It is important to ensure that any pipes crossing beams are properly supported to avoid any structural damage.

    What is used in water pipelines to absorb the shock caused by water hammering?

    • Shock regulator

    • Air chamber

    • Water regulator

    • Shock absorber system

    Correct Answer
    A. Air chamber
    Explanation
    An air chamber is used in water pipelines to absorb the shock caused by water hammering. Water hammering occurs when the flow of water is suddenly stopped or changed direction, causing a sudden increase in pressure. The air chamber acts as a cushion, absorbing the shock and preventing damage to the pipes and fittings. When water hammering occurs, the excess pressure is absorbed by the air in the chamber, reducing the impact and preventing the pipes from banging or vibrating. This helps to maintain the integrity and longevity of the water pipeline system.
