What might signal a need for immediate attention in a water distribution system?

Sudden pressure variations and visible leaks indicate potential issues in a water distribution system that could lead to serious consequences if not addressed promptly. Pressure variations might suggest that there is a break or malfunction in the system, which can lead to inefficiencies and the risk of a catastrophic failure. These variations can also compromise water quality or service delivery. Visible leaks often imply a significant issue that could result in water loss, increased operational costs, and potential damage to infrastructure. Together, these factors signal an urgent need for maintenance or repairs to ensure the system functions correctly and safely.

While high water levels in tanks and regular customer complaints may suggest areas for improvement, they do not typically signify immediate dangers to the system. Enhanced fire safety measures are proactive steps that are important but not indicative of a true emergency. Therefore, addressing pressure variations and leaks is crucial for the integrity of the water distribution network.
