True or False: Rocks or blocks can support drainage piping inside a trench at any point.

• A. True
• B. False
• C. Only if they are stable
• D. Only during installation

Answer: (B)

The statement is false because drainage piping should not be supported by rocks or blocks inside a trench at any point. Proper installation requires that the pipes be laid on a bed of 3/4-inch gravel or similar material to ensure proper alignment and to facilitate drainage without causing damage to the piping. Supporting the pipes with rocks or untested materials can lead to improper installation, potential blockages, and issues with the gravity flow of drainage systems. While physical stability of the materials may seem like it could support the piping, the risk of movement, shifting, or settling over time makes using rock or blocks as a support unsuitable. It is vital to maintain the integrity and functionality of the drainage system by using appropriate materials and methods as per standard installation guidelines.
