A network of intermediate-sized pipe by forming loops that interlock primary feeders is called?

• A. Primary loop
• B. Secondary feeders
• C. Distributors
• D. Grid network

Answer: (B)

When thinking about how a fire protection water system is laid out, pipes are often described by their role and size in a hierarchy. Large-diameter mains carry water from the sources and are called primary feeders. The pipes that run between those mains, of intermediate size, and that form interconnected loops around and between the primaries to create a network are known as secondary feeders. This looping, interlocking arrangement helps maintain reliable water supply and adequate pressure by providing alternate paths if one section is shut off or damaged, and it distributes water toward smaller service lines and hydrants. The other terms don’t capture this specific intermediate-level looping around the large mains: primary loop and grid network are more general descriptors, and distributors refers to distribution lines without specifying the looping secondary feeders.
