Final answer:
The statement that all visible wastes, drains, and vents should be inspected is true, as regular inspections prevent health hazards and maintain plumbing system integrity.
Step-by-step explanation:
All visible wastes, drains, and vents should indeed be inspected to ensure that plumbing systems are functioning correctly and to prevent potential health hazards. Regular inspections can identify blockages, leaks, or other issues that may lead to unsanitary conditions or compromise a building's structure.
Furthermore, ensuring that vents are clear is essential because they help in maintaining the drainage system's pressure balance and removing sewage gases and odors. Inspections help in preventing health risks by detecting early signs of potential problems that could lead to mold growth, water contamination, or pest infestations.
While it's essential to inspect visible wastes, drains, and vents regularly for proper maintenance, not all of them need to be visible. Some may be concealed within walls or structures. Routine inspections help identify potential issues and ensure the proper functioning of plumbing systems, promoting a healthy and efficient environment.
Therefore answer is B) False.
