Which statement about gravity dump systems is true?

Which statement about gravity dump systems is true?

• A. Gravity Dumps Rely On Nature's Gravitational Pull
• B. Gravity Dumps Require A Power Source To Operate
• C. Gravity Dumps Cannot Be Closed Electronically
• D. Gravity Dumps Typically Use Long Hoses

Answer: (A)

Gravity dump systems move water purely by gravity. When the discharge is opened, water flows downhill from the elevated tank due to its weight and the height difference, without needing a pump or external power. That reliance on gravity is what makes this statement true. The other points aren’t universal features: they don’t require a power source, electronic closures are possible in some setups, and using long hoses isn’t a defining, requirement for gravity dumps.
