What is one disadvantage of a non-looped water distribution system?

A non-looped water distribution system has the disadvantage of a higher likelihood of pressure fluctuations. In such systems, water flows in a single direction from the source to the end users and does not have alternative pathways for water to travel. This setup can lead to variations in water pressure, especially during peak demand times or if there is a disruption in the water supply, such as a break in the pipeline.

In contrast, a looped system enhances pressure stability because there are multiple routes for water to flow, which can help balance out the pressure differences throughout the system. Therefore, the absence of this feature in a non-looped system can make customers more susceptible to fluctuations in water pressure, impacting the reliability of service and the performance of water-using appliances.

The other options do not accurately represent the disadvantages of a non-looped system. For instance, increased redundancy and greater customer accessibility are benefits typically associated with looped systems, while lower maintenance costs may not necessarily apply, as maintenance can be affected by various factors beyond the looping of the system.
