While we're at it we could score higher on the Martian intelligence test by universally adopting saner basis vectors for the control space in the first place--namely temperature and total water volume, rather than
hot-volume and cold-volume.
I recall my first trip to Israel, when I was confronted with a shower
that had *three* water control knobs. Being a cautious sort, I tried
turning each one on, one at a time. No water ever came out.
The knobs, of course, were rates for hot, cold, and total, all initially set to zero. This does offer all the advantages of both systems...

If you open Hot and Cold, but close Total, will water of one temperature be forced by pressure difference into the pipe for the other temperature water? Gene __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/
