What can increased water bills indicate in a plumbing system?

Increased water bills are often a strong indicator of potential leaks within a plumbing system. When leaks occur, water is being wasted without the homeowner's knowledge, leading to higher consumption reflected in monthly bills. Identifying and addressing these leaks promptly not only helps in reducing water waste but also prevents further damage that could result from prolonged leaks, such as mold growth, structural damage, or increased utility costs.

In contrast, improved water efficiency would typically lead to a decrease in water bills, not an increase, while improved plumbing performance usually suggests that the system is working well, which also would not typically cause increased bills. Water pressure fluctuations might indicate issues within the plumbing system but are less directly connected to the average water consumption that would be reflected in monthly bills. Thus, the significance of monitoring water bills to detect potential leaks cannot be overstated.
