Explanation:
In a water supply system, several components and valves are provided to ensure the efficient and safe distribution of water. The given statements discuss the role of drain valves and reflux valves in the system. Let's analyze each statement and determine their correctness.
1. Drain valves are provided at elevated or higher points to remove accumulated air:
- This statement is correct.
- Drain valves are installed at elevated or higher points in the water supply system to remove accumulated air pockets or trapped air.
- Accumulated air can hinder the flow of water, reduce system efficiency, and cause issues such as water hammer.
- By providing drain valves at elevated points, the accumulated air can be released, ensuring proper water flow and preventing any potential problems.
2. Reflux valve allows flow in one direction only:
- This statement is correct.
- A reflux valve, also known as a check valve or one-way valve, allows the flow of water in one direction only.
- It prevents backflow or reverse flow of water, ensuring that water flows only in the desired direction.
- This valve is essential to prevent contamination of the water supply and maintain the integrity of the system.
3. Drain valves are provided at low points to remove silt and other deposits:
- This statement is correct.
- Drain valves are also installed at low points in the water supply system to remove silt, sediment, and other deposits that may accumulate over time.
- These valves allow the flushing out of debris, ensuring the quality of water and preventing any blockages or obstructions in the system.
- Regular maintenance and cleaning of drain valves at low points are crucial to maintain the efficiency and longevity of the water supply system.
Conclusion:
Considering the given statements, it can be concluded that statements 2 and 3 are correct. Therefore, the correct option is 2 and 3 only (option C).
