There are things that I absolutely can not stand - this is part of being patronized as a consumer. Grohe does. Why? I looked for 2 days after the "failure" why ridiculous from the fitting 4 liters / minute flow (at 2.5 bar pressure). A 4-year-old Grohe faucet almost of the same model shows 8 liters / min. , Or twice. Measurements, flow limiter adjusted in fitting and research followed. What came out? Grohe installed a water saving Mosseur! He is recognizable by the red grid when unscrewing it. The normal is blue and actually makes the double flow. So I must now buy more blue. Mind you, they only exist in a double, 1 piece blue and 1 piece of red. So I can throw away 2 red to use a blue - great! (Grohe Mousseur 13,937,000)
It's my business if and how I want to save water, and not the decision of anyone else. There are 2 penalty points an otherwise impeccable, and especially entirely of metal fabricated fitting.
