What does EPAct require regarding plumbing fixtures?

The Energy Policy Act (EPAct) focuses on promoting energy efficiency and conservation, which includes significant provisions aimed at reducing water consumption in plumbing fixtures. Under the act, specific standards are established for various fixtures, such as faucets, showerheads, and toilets, to ensure that they use less water while still providing adequate performance.

By mandating that plumbing fixtures meet specific standards for water efficiency, the EPAct encourages both the conservation of water resources and reduction of energy used in water heating. This approach aligns with broader environmental goals and supports sustainable development practices, making option B the correct choice in addressing the requirements of the EPAct regarding plumbing fixtures.

The other options touch on aspects that are not specifically mandated by the EPAct. For instance, sustainable materials for fixtures, installation by licensed professionals, and warranties are not required under the stipulations of the EPAct, focusing instead on the reduction of water consumption as a primary objective.
