Which term refers to appliances used when a larger volume of water is needed at the end of a main supply line, sometimes called portable hydrants?

• A. Larger diameter hose appliances
• B. Wye
• C. Siamese
• D. Water thief

Answer: (A)

When you need more water delivered to the end of a main supply line, the device used is a water thief. This appliance is designed to draw additional flow from a large-diameter supply and feed it into the attack line or a smaller hose, effectively increasing the volume available at the point of use. It’s sometimes called a portable hydrant because it provides a ready source of water at the end of the main line, without relying on another hydrant close by. A Wye fitting, by contrast, splits one supply into two separate lines, spreading the flow rather than increasing the total volume. A Siamese fitting combines two lines into one to boost capacity at a single point, but the situation described—getting a larger volume specifically at the end of the main line—aligns more directly with what a water thief does. The phrase larger diameter hose appliances refers to the broad family of LDH devices, but the precise term for this purpose is water thief.
