Which type of equipment would not require electrical power?

• A. An exhaust fan.
• B. A pump alternator.
• C. A jet flushing system.
• D. A light system.

Answer: (C)

A jet flushing system operates by using pressurized water to create a strong jet that cleans and clears sewer lines. This system relies on the force of water flow rather than electric power, making it different from other options listed which rely on electrical components for their operation. In contrast, exhaust fans, pump alternators, and lighting systems typically require electrical power to function. Exhaust fans need electricity to power the motor that drives the fan blades, pump alternators are dependent on electrical current to control and switch pumps, and light systems require electricity to illuminate. Thus, a jet flushing system stands out as it operates purely on hydraulic energy rather than relying on electrical energy, making it the correct choice in this context.
