Which measure is recommended to protect cold water pipework from physical damage and contamination in a building?

• A. Proper support and securing
• B. Protection of pipes through walls
• C. Painting pipes
• D. Avoiding contact with soil

Answer: (A)

Securing and supporting cold water pipes properly is about control and stability. When pipes are well supported with appropriate hangers, straps, and clamps at the correct intervals, they stay in place, resist movement from thermal expansion, vibration, or accidental contact, and are less likely to bend or pull on joints. This stability keeps the system from developing leaks or failures that could allow contaminants to enter the water path. In short, solid support and securing protects the physical integrity of the piping and helps maintain water cleanliness by preventing weaknesses that could lead to leaks.

Other options don’t provide the same level of ongoing protection. Protecting pipes through walls can shield them from some surface damage, but it doesn’t address how the pipes move or vibrate over time. Painting pipes doesn’t add structural protection and won’t prevent damage or leaks. Avoiding contact with soil is more relevant for buried or exterior pipe segments and isn’t the general measure for protecting interior cold water piping from physical damage and contamination.
