With tap water being available for more than 100 years now, most people know how to access it, and an ideal design seem to have emerged: two faucets, one for hot water, one for the cold, feeding a single output pipe. Easy to adjust the temperature, easy to adjust the flow. What’s not to like!
But apparently some designers just can’t go a day without spoiling a good thing. Check out this contraption, for example:
The single lever controls both the flow and the temperature – as you rotate the lever counter-clockwise, the temperature increases, but the flow increases only up to the middle point, then decreases again somewhat. Peak flow comes at a fairly comfortable “almost hot” temperature point.
As a result, you can’t get, say, a strong stream of cold water, or, if your personal temperature sweet spot is different from the designer’s, you can’t get the full flow of your favorite temperature.
This is of course a much better design still than this invention of a sadistic mind:
Either burn your hands with 100% hot water or freeze them with 100% cold water. No mixing, mixing is for pussies! The best you can do is move your hands frantically between the hot and cold streams. Burn-freeze-burn-freeze-burn-freeze. Don’t forget the soap, chap!
