An open distribution system is commonly referred to as a looped system. This type of arrangement typically involves multiple pathways for water to travel within the distribution system, allowing for improved circulation, redundancy, and better pressure maintenance. Loop systems are advantageous because they minimize dead ends and reduce the risk of stagnation and water quality deterioration.

In a looped system, if one section of the pipe fails or needs maintenance, water can still be delivered to consumers from alternative routes. This feature is not present in other systems, which may have more limitations in their flow paths. While branch and single-serving systems have their place in distribution networks, they do not offer the same level of connectivity and resilience that a looped system provides, thus solidifying the term "open distribution system" with the correct alignment to a looped system.
