What might be a common consequence of not addressing water hammer in plumbing systems?

The consequence of not addressing water hammer in plumbing systems often leads to pipes wearing out more quickly. Water hammer refers to the pressure surge that occurs when a fluid in motion is forced to stop or change direction suddenly. This shock wave creates stress on the pipes and fittings, which can lead to fatigue and eventual failure over time.

When water hammer is present, the repeated stress can cause joints to loosen, fittings to break, and ultimately lead to leaks or ruptures in the piping system. Such damage may escalate the need for costly repairs and increase maintenance frequency.

The other options, while potentially relevant to plumbing systems, do not directly relate to the immediate mechanical stress and deterioration caused by water hammer. Miscalculating fixture loads or interruptions in water supply are more about system design and operational issues, while significant expansion of pipes is not typically a direct outcome of the water hammer phenomenon.
