The network of intermediate-sized pipe that forms loops interlocking primary feeders is known as which?

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

Answer: (B)

In water distribution, large mains that carry water from the source are called primary feeders. The pipes of intermediate size that connect these big mains and create looping paths around them are secondary feeders. This looping network provides redundancy and helps balance pressure, ensuring reliable fire flows throughout the area. Distributors are the smaller lines closer to customers, and a grid network is a general way to describe layout rather than a specific layer of piping. So the network of intermediate-sized pipe forming loops interlocking primary feeders is secondary feeders.
