But suppose you want to wash your hands in water warmer than the water from the cold tap, and cooler than the water from the hot tap, and rinse them in clean water of the same temperature. With 2 taps: Plug sink Turn on both taps Mostly fill sink Turn off both taps Mix water in sink and test temperature Add more water from one tap to obtain desired temperature Wash hands Drain sink Plug sink Turn on both taps (getting them soapy) Mostly fill sink Turn off both taps Mix water in sink and test temperature Add more water from one tap to obtain desired temperature Rinse hands Drain sink Plug sink Turn on both taps (getting your hands soapy) Mostly fill sink Turn off both taps Mix water in sink and test temperature Add more water from one tap to obtain desired temperature Rinse hands and taps Drain sink With a single faucet and independent temperature and pressure controls: Adjust pressure Adjust temperature Wash hands Rinse hands Turn off water I find the latter much more usable. Of course, if you don't mind rinsing your hands in dirty, soapy water (getting them dirty again, so why bother washing them in the 1st place?), you can make the 2-tap scenario much shorter. Of course, 2 separate taps are hopeless for showering ... -- Jeff Carter "English bed-wetting types."
