Which appliance divides one hoseline into two outlets, typically with one 2.5 inch outlet and two 1.5 inch outlets?

• A. Clapper valves
• B. Wye (Gated wye)
• C. Siamese
• D. Water thief

Answer: (B)

Splitting a single hoseline into two branches is what the gated wye is designed to do. It provides one inlet connection (usually 2.5 inches) and two outlets (typically 1.5 inches each), with gates on the outlets so you can control flow to each branch independently. This lets you feed two attack lines or appliances from one supply line, while being able to shut off or throttle either branch as needed without affecting the other. Other devices serve different purposes. A Siamese combines two lines into one to increase flow to a single outlet, which is the opposite of splitting. Clapper valves are one-way checks used to prevent backflow in such assemblies, and a water thief is used to siphon or shuttle water from one source to another rather than simply splitting a line.
