Which of the following is a potential consequence of inadequate water pressure?

Inadequate water pressure can significantly hinder the ability to fight fires effectively. Firefighting relies on sufficient water pressure to deliver water at the necessary flow rates to combat flames. When pressure is low, firefighters may struggle to obtain the volume of water required for effective suppression, which can prolong firefighting efforts and increase the risk of fire spreading. This is particularly critical in urban areas or regions with high-density buildings where quick access to water is essential for controlling fires and protecting life and property.

The other options do not align with the consequences of inadequate water pressure. For instance, increased water quality and reduced water treatment costs do not necessarily correlate with pressure levels; in fact, low pressure may sometimes compromise water quality by allowing contamination to enter the system. Additionally, better system efficiency is unlikely in conditions of inadequate pressure, as the distribution system may become less effective at delivering water where and when it is needed, leading to increased operational challenges rather than improvements.
