Provide two examples of water-efficient fixtures.

• A. Low-flow faucets and low-flow toilets
• B. High-flow faucets and standard toilets
• C. Conventional faucets and large-capacity toilets
• D. Low-flow toilets and high-flow spouts

Answer: (A)

This item tests recognizing fixtures that save water by reducing how much you use per use. Two classic water-efficient fixtures are low-flow faucets and low-flow toilets. Low-flow faucets limit the water leaving the tap, often using aerators or regulated valves to deliver acceptable performance with less water—typically around 0.5 to 1.5 gallons per minute depending on pressure. Low-flow toilets restrict the water per flush, commonly 1.28 gallons or less, which dramatically cuts daily water use while still flushing effectively. The goal is to meet user needs while using less water, a principle that high-flow or conventional options don’t meet.
