Yeah, or even if the motion detector is more fussy & you have to be
at the sink, what if you don't need hot water? Like brushing your
teeth, or giving something a quick rinse. Heck, in the summer, the
tap water is warm enough for most washing uses, so I frequently don't
use the hot water while I'm at the sink, whatever I'm doing.
