Question

Cast-iron soil pipe, installed vertically, shall be supported at its base and ________?

1) at regular intervals along its length
2) only at the top
3) only at the bottom
4) at irregular intervals

Answer 1

Cast-iron soil pipe should be supported at its base and at regular intervals along its length to maintain stability and prevent damage.

Step-by-step explanation:

Cast-iron soil pipe, installed vertically, shall be supported at its base and at regular intervals along its length. This is to ensure that the weight of the pipe and the contents it carries are evenly distributed, preventing any excessive stress on the pipe or potential damage.

By supporting the pipe at regular intervals, it helps to maintain the stability and integrity of the installation. This helps to prevent any sagging or potential failure of the pipe due to its own weight and the pressures it may encounter.

For example, in a tall building, the vertical cast-iron soil pipe would need to be supported at each floor to ensure that it remains stable and properly aligned, without creating any undue stress or strain on the pipe itself.
