This article probably applies to kitchens too.
Notice how modern taps are lever style? Old style are the kind you turn. I call them "dials" but I don't know if that is the correct industry term.
Years ago I worked in an office tower that renovated. One of the changes were the dial taps were replaced with lever taps. Thereafter men hit those levers upwards and washed their hands with full blasts of water. With dial taps this never happened. Usually guys would stop at about a quarter turn and adjust the water flow to a comfortable rate.
Here is my technical analysis. A lever needs only move in one direction (up) in order to range the full force of water. And they are very easy to push upwards to 100% water flow. A dial tap needs turning. For example, one full turn might equal 100% water flow. Very rarely would anybody take the effort to turn a dial to full flow. It just doesn't happen because it is unnecessary and requires a little extra effort. I guess maybe dials are turn from 1/4-1/2 flow.
I wonder how much water is wasted on those stupid f****** lever taps. I'm raging again because it is yet another example of making the world worse off than better.
On the other hand, maybe the new faucets had better aerators.
If anyone knows of any water usage comparitive studies on this, please let me know. It'd be interested to see if water use goes up after a renovation in an office tower.
