In a sprinkler system, what defines a looped sprinkler system?

A looped sprinkler system is characterized by multiple paths for water flow. This design enhances the system's efficiency by ensuring that water can be delivered to the sprinklers through several routes. If one section of the loop is blocked or experiences a malfunction, the water can still reach the sprinklers through alternative paths, reducing the risk of system failure and ensuring adequate coverage.

Having multiple pathways also allows for even water distribution across the area being irrigated, which is crucial for maintaining healthy vegetation. Additionally, this configuration can help maintain system performance under varying pressure conditions, as it mitigates the risks related to pressure fluctuations that can occur in single-path systems. Maintaining high pressure or ensuring constant water presence are factors that may optimize a sprinkler system, but they do not define the characteristic structure of a looped system.
