The only reason I can think of is for the asthetics as having it separated might make it look a little out of place. But you know, after spending as much money as we are spending on our rooms (as in a small fortune) I think we should be able to put the darn faucets where ever they would be most comfortable for our own use...don't you?

I'm trying to make that same decision myself. There have been other threads on the same subject. Argument for: Convenience and great look. No need to lift a heavy pot out of the sink and maybe scratch or chip a fire clay sink. Faster fill bec pot fillers suposedly produce more gpm (but not all, some were still 2.5 gpm). Neighbor has hers plumbed to the hot water line. ..(One GW'r said not to drink water from hot line, but another said it didn't matter bec they no longer use lead solder.) Argument against: Wouldn't really use it that much. Extra expense (rough plumbing and fixture cost, $300 - $1000 ?? More things to leak and go wrong. Do you match to shape and finish of main faucet? Just a few things to consider ... HTH

Datura-07, from Ccoombs1's link: Do not consume water that has sat in your homeÂs plumbing for more than six hours. First, make sure to run the water until you feel the temperature change before cooking, drinking, or brushing your teeth, unless otherwise instructed by your utility. (emphasis mine) I would add, that what actually happens is that the water temperature changes twice b/f its ready to use.... I seem to recall reading somewhere that for a house w/the "average" amount of piping for water to flow through it takes somewhere b/w 1 & 2 minutes But, that was a long time ago so I may not remember correctly. I use the water temperature method. You can collect that water & use it to water plants (inside & outside)...that's what I usually do, especially in the summer when I have containers on the back deck & front porch. One thing to remember is that even if you have PVC piping, there are probably copper pipes leading into/out of your hot water tank and possibly the intake from your well or public water source. I think the person who put in a small chef's sink had a good idea. The pot filler wouldn't have to be right over it, as long as it could reach it easily it would be fine...so you get the look & functionality of a pot filler with the safety net of a drain. For leaks inside the wall...yes, there is a possibility of this and it's like a shower head that also comes directly from a wall... But, if you have access from the other side of the wall you may not have to disturb your tiled backsplash for repairs. That's assuming, of course, that your pot filler is on an inside wall. Oh! That brings up another point... If your pot filler is on an outside wall, be sure it is very well insulated to prevent the pipe from freezing & bursting! [For those of us who live in areas where we have below freezing temperatures.] BTW...it's not just pot fillers that are at-risk for overflowing...I did that once when I filled a pot next to my prep sink. The faucet head was docked on the edge of the pot to fill & I got distracted. The advantage I did have, though, is that w/the sink right there I could dump the excess water from the pot and "sweep" the overflowed water into the sink.

you can mix, but most people do the same as the faucet. What kind of backsplash tile are you doing?
