What type of system consists of interconnected pipes that create looped paths for water flow?

A system that consists of interconnected pipes creating looped paths for water flow is referred to as a Loop System. In this setup, the looped configuration allows for multiple routes for water to flow, which can enhance the efficiency and reliability of the sprinkler system. If one part of the loop is compromised or needs maintenance, water can still flow through alternate paths, ensuring that coverage and pressure are maintained throughout the system. This design is particularly beneficial in larger facilities where consistent and reliable water distribution is critical for effective fire suppression.

In contrast, a Grid System refers to a configuration typically used in larger applications where the layout is designed with a grid to ensure water can reach various heads efficiently, but it may not always have the same looped paths that a Loop System features. A Branch Line System generally consists of straight runs of pipes branching out to individual sprinkler heads, which lacks the interconnected routing characteristic of a Loop System. A Control Panel System relates to the equipment that manages the fire protection system but does not describe the physical layout of the piping and water flow, making it unrelated to the question about the type of system based on interconnected pipes.
