Why aren't you plumbing your kitchen faucet to use filtered water instead of using a separate unit? A simple under cabinet filtration system would work just fine in line to your Karbon.

cotehele-- I have had the Harrington Brass wall mount faucet installed for a few years now. The faucet seems to be very well made, nice finish etc. which has held up nicely. But--I do have one issue with it, which is a bit hard to describe.... Sometimes it is VERY difficult to push in the lever on the hand spray to turn on the flow. It is almost like some kind of vacuum effect is causing the problem, I'm not sure. I can usually jiggle the lever back and forth a bit to free it up again. When I first got the faucet installed (several years ago now...) the problem started up within a couple months. I emailed Harrington Brass about it and they sent me a new hand spray immediately. The new one had worked trouble free up until a month or so ago, when it started sticking as well. I haven't seen any feedback from other owners of this faucet type, so I don't know if this is a problem with my setup or a general problem with the faucet design--I tend to think it's a design issue. With that said, I am still happy with the faucet--love how it looks and it is nice to have the side sprayer, even with the problem I described. But, if you aren't partial to that style aesthetically, I'll bet the Chicago faucet is the best bet. It looks like a different design from the other two, so I'll bet you wouldn't run into the issue I've had with that model. Plus I think they are supposed to be great faucets (and a better price I'll bet!) Here is a picture of my faucet....

instead of posting a never ending series of paragraphs about fine grained details, i prefer to hold off until the thread takes a new direction and receives new input. That is a way for me to ensure two things related to sanity and balance. One is (a) that I get something in return, e.g. perhaps some new twists, new ideas, new views, new information and the other is (b) that I only spend an hour or two here and there instead of all my life in "being helpful" to no end. At this point in time to the best of my recollection you have asked me for nothing at all that is specific, so it is fine if in this post I give you nothing of any significance in terms of content here. b.t.w. From the tapmaster site: "What powers the Tapmaster? The water pressure that exists in the hot and cold water lines powers the Tapmaster. The Tapmaster is a set of valves, which uses the water pressure existing in your water lines to operate (hydraulically), and therefore requires absolutely no electricity. When the Tapmaster is installed the system pressurizes automatically and is ready to turn the water on and off. b.t.w. i'll bet your architect will love being given the mandate to draw a spout. There may have already been a billion spouts made since the days of the Roman Empire and the Qin/Xian dynasty, and nobody ever needed a drawing back in those days. Now, we've become a litigious society, and we always want to keep re-doing things until they're perfect, so everybody asks for drawings. I would say to the welder, hey, anything that you can make, with a minor bend in it. For a visual inspiration to see a tube bent into a spout, he could look at the 135 degree angle of this spout: K-952-CP STILLNESS . You may want more bend than that. If it's welded, you don't need the round thingie at the base (escutcheon) but unless you say this to the architect, he / she might not think to eliminate it in the drawing. The shape you want is a thin thin thin tube or pipe. If you weld two tubes together, you could have a stronger spout and a spare spout too. Or three tubes. One day, your filtered water could go into an instant hot tank and that could feed the second spout. Hint hint. If you weld two together, the two tubes could be side by side or one on top of the other. The idea of welding parallel thin tubes is that you get your mechanical support from the multi-walled-ness of the 2 or 3 tubes being put into a unit all together as one. The welder might say that a single thin thin tube will one day get bumped and then broken or bent. The place where the tube connects to the backsplash is a weak spot where he will want to "spread" the base so that the backsplash stays flat and doesn't warp there. Check into the filter you bought. Some of them give high flow outputs. Good to know now. Hth
