Which scenario illustrates a consequence of not managing pipe expansion?

Not managing pipe expansion can lead to the development of leaks within the plumbing system. This typically occurs when temperature changes cause pipes to expand and contract. If the pipes are not allowed to move freely or if they are improperly secured, the stress from expansion can create weak points or joints that eventually lead to cracks or separations, resulting in leaks. Proper management of pipe expansion is crucial to maintain the integrity of the plumbing system and to prevent water damage and loss from leaks.

The other scenarios listed do not relate directly to the physical stressors and potential failures caused by unchecked expansion. Enhanced durability, for example, implies improved resilience but does not address the specific risks associated with thermal changes. Inconsistent water pressure and improved aesthetics also do not have a direct causal link to the management of pipe expansion in the same way that leak development does.
