What impact does thermal expansion have on plumbing systems?

• A. It reduces the pipe's lifespan
• B. It can cause leaks or breaks
• C. It enhances water flow
• D. It increases structural integrity

Answer: (B)

Thermal expansion significantly impacts plumbing systems primarily by causing materials to expand and contract with temperature changes. When water heats up in pipes, it expands. If there is insufficient room for this expansion or if pipes are rigidly fixed in place, the increased pressure can result in leaks or breaks. For example, metal pipes may expand with hot water and, if they are restrained, the stress of the expansion can lead to cracks or ruptures in the pipe. This is particularly problematic in systems with temperature fluctuations, such as those found in heating systems, or when hot water is suddenly introduced into a cold pipe. Properly addressing thermal expansion with techniques such as using expansion joints or flexible connectors can mitigate these issues, but failure to account for it can lead to serious plumbing failures and costly repairs.
