What is the name of the device that splits one hose stream into two hose streams?

The device that splits one hose stream into two hose streams is called a Wye. This apparatus is specifically designed to allow a single water supply to effectively distribute water to multiple outlets simultaneously. In firefighting scenarios, this is particularly useful as it allows for more flexible and strategic deployment of water streams, enabling firefighters to cover larger areas or address multiple fire threats at once without needing additional water sources.

The design of the Wye typically includes two female connections at the "split" end, which attach to separate hoses, and one male connection that attaches to the original hose. This configuration makes it simple to utilize one supply line to feed several hoses, maximizing efficiency during firefighting operations.

Understanding the function of a Wye is critical for tactical firefighting operations, particularly in coordinating multiple teams or when dealing with extensive fire scenarios where time and resource management are essential.
