LEED AP with Operations and Maintenance (O+M ) Practice Exam

Which of the following can have a WaterSense label?

1. Residential dishwashers

2. Water-using urinals

3. Both private lavatory faucets and water-using urinals

4. High-efficiency washing machines

The correct answer is: Both private lavatory faucets and water-using urinals

The WaterSense label is a certification created by the U.S. Environmental Protection Agency (EPA) that signifies a product or service meets water efficiency and performance criteria. The correct answer, indicating that both private lavatory faucets and water-using urinals can have this label, reflects the comprehensive approach of the WaterSense program toward various fixture types that contribute to water conservation in residential and commercial settings. Private lavatory faucets can receive the WaterSense label because they are widely used fixtures where water efficiency can lead to significant reductions in water consumption. These faucets are designed to use at least 20% less water than standard models without sacrificing performance, making them an essential element in water-saving efforts within buildings. Water-using urinals are also eligible for the WaterSense label, particularly high-efficiency models that are designed to reduce the volume of water they use per flush compared to traditional urinals. This is crucial in reducing overall water usage, especially in high-traffic environments where urinals are commonly found. The other options, while relevant to water conservation efforts, do not encompass the full range of products covered by the WaterSense program. Residential dishwashers and high-efficiency washing machines, while they may have energy-efficient labels, are not included under the WaterSense
