You can get to propose with this counter, fun challenges, such as spending less water each day. One can, if need be, choose to open the Sensor Faucets on a regular basis if necessary to fill the basin of water (some little green, by the way).Another advantage is that the tap will never be leaking by closing it wrong. Based on the mechanism of hand dryers that are Waterfall Faucets in many bars and restaurants, this faucet is a great help to save water without even having to worry about it.
