WELL is a product classification system devised by the European association of Valve manufacturers (EUnited Valves).
Similar to the EU energy-efficient labelling, already found on the majority of white goods such as dishwashers and washing machines, WELL was established to promote responsible water usage and to provide an easy-to understand evaluation system for consumers and professionals.
For single-lever basin mixers, the WELL assessment categories are:
- Volume (flow rate)
A two-star classification is the maximum that can be achieved in each category.
GROHE EcoJoy™ basin mixers have achieved the maximum total of four stars resulting in an a rating.
