For Sale and pick-up in San Francisco is a Haas Mfg. Intellifaucet water temperature regulator, hot and cold water filter holders, extra set of new filters and as much as you want of the plumbing and hardware in the photos beyond the shut offs. The current Intellifaucet and more info can be seen here http://www.hassmfg.com/search.pl/130...&submit=Search
I tested it on Monday and it works perfectly. Power is provided by the low voltage transformer that plugs in to a wall socket and then into the Intellifauce (it's sitting on top of the blue cold water filter.) Bought new and only used for a few projects over the course of a year.
$100 if you pick it up; $175 shipped to you in US.
