A hydrant with the largest capacity is connected to which part of the system?

A hydrant with the largest capacity is connected to which part of the system?

• A. Secondary line
• B. Standpipe
• C. Forward hydrant
• D. Primary feeder

Answer: (D)

The main idea here is how a water supply network is arranged. The primary feeder is the main supply line that brings the largest volume of water into the system and feeds the distribution network. Hydrants connected to this line are designed to deliver the greatest flow, because they are tapping into the backbone of the water supply before any branch lines lose pressure or capacity. Secondary lines branch off from the feeder to serve individual hydrants or areas and typically have smaller piping, which reduces the maximum flow available at each hydrant. Standpipes are vertical building piping, not the exterior main supply, and a forward hydrant is used for a specific operational setup rather than for providing the largest capacity. So, the hydrant with the largest capacity is connected to the primary feeder.
