The Oras Vega wash basin faucet has a unique eco-button that will help you to save both water and energy, and thereby also money. When you turn on the faucet, the flow rate will at first be lower. If you need more water, simply press down the eco-button and lift the lever at the same time. In wash basin and shower faucets, the eco-button also improves safety by functioning as a temperature limiter.
