What is the advantage of stopping the apparatus short of the hydrant?

• A. Reduces friction loss
• B. Increases pump efficiency
• C. Allows the hose curve preventing kinks
• D. Improves water flow

Answer: (C)

Stopping the apparatus short of the hydrant lets the supply hose form a gradual curve to reach the hydrant instead of forcing a sharp bend right at the connection. That smooth curve prevents kinks, which can block flow or create high resistance in the line. By avoiding a tight angle, water can move freely through the hose, the pump maintains a steadier flow, and the hose and fittings are less stressed. Other effects like friction losses or pump efficiency aren’t as directly impacted as the prevention of a kink, which is the key practical advantage here.
