As of April 2011, most water-using appliances and many plumbing fittings are required to display a Water Efficiency Labelling Scheme (WELS) label. The WELS label lets you identify products that use less water. It applies to washing machines, dishwashers, toilets, urinals, showers, and taps.
It displays two types of info:
- A star rating that shows relative water efficiency for the same type of product. The more stars, the more water-efficient. Most products have a maximum of 6 stars; but in the short term, showers will have a maximum rating of 3.
- A water consumption or flow-rate figure of litres per minute for taps. The label for taps will also say if the product is designed for mains or low-pressure water systems.
