Which appliance can a firefighter use to split a 2.5" or 3" line into two 1.75" lines?

The gated wye is designed specifically for situations where you need to split a larger diameter hose, such as a 2.5" or 3" line, into two smaller diameter lines, like 1.75" lines. This feature allows for efficient distribution of water to multiple attack lines from a single large supply line. The gated wye includes valves (gates) on both splits which provide the capability to control the flow to each of the smaller lines individually, enhancing operational flexibility at the fire scene.

Using a gated wye maximizes the utilization of the water supply by allowing multiple crew members to operate simultaneously from the same source, improving the firefighting response. Its design is intentionally made for this purpose, ensuring both efficacy and safety during operations.

In contrast, options like the wye strainer, drip torch, and jet siphon serve entirely different functions. The wye strainer is used primarily for filtering water to prevent debris from clogging hoses and nozzles. A drip torch is utilized in controlled burns to help ignite materials with a consistent flame, and a jet siphon is employed for moving water or creating a vacuum effect but doesn't facilitate splitting lines for firefighting operations. Hence, the gated wye is the appropriate tool
