What is an important safety measure when inspecting plumbing systems?

Turning off water and power supplies before starting inspections is crucial for ensuring safety during plumbing inspections. This action minimizes the risk of electrical shock, water leaks, or other hazards that could arise from energized or pressurized systems. When conducting inspections, one must prioritize personal safety and the integrity of the plumbing system, which is why disconnecting power and water is a fundamental precaution.

In addition to enhancing safety, this practice allows the inspector to work more comfortably and thoroughly without the complications that active systems can present. It is essential to create a controlled environment where potential dangers from water flow or electricity are entirely mitigated, allowing for a more effective and comprehensive inspection.
