About a year and a half ago, my company replaced the faucets, toilet flushers, and paper towel dispensers with units equipped with motion sensors. While this may have seemed like a good idea to someone, particularly the toilet flushers, the reality is that half the time they don’t work and you have to use the manual flush button anyway. With the faucets, you have to position your hands just right in order to get them to turn on and if you move your hands out of position the water flow stops. You also have no control of the temperature. I just went to the rest room and saw one of the faucets apart so the battery could be replaced. Having done some shopping for assorted bathroom components over the years it is obvious that these electronic fixtures must be substantially more expensive than conventional units. And since a technician must be called every time one of these things stops working (which is pretty frequently) it sure doesn’t seem like they could be saving any money in reduced water costs. but what do I know I’m just an engineer not a facilities manager.
