Question:
Our kitchen sink has a faucet for cold hard well-water and anotherfaucet for hot/cold softened water. We are replacing the sink andfaucets and will add a reverse osmosis filter (and a faucet for the ROwater).

Should we keep access to hard water? I am tempted to abandon it andjust have the main hot/cold/softened and second RO drinking water.

If the dish-drainer is to the right of the sink, should I put the ROfaucet to the left or the right of the centered main faucet?

Answer: I'm with you on this - get rid of it. I can't think of a reason to keep itunless you one of the very few people who have to avoid sodium. At one timeit was thought that all people with high blood pressure should avoid sodium,but that has been largely discredited. Even if you are one of the few youcan use potassium chloride in you softener instead of sodium chloride. Ifyou are intent on adding extra taps to your sink, you might consider aninstant hot water dispenser. I think that Kohler sells a tap that candispense two sources of water - one for reverse osmosis and instant hotwater, or you could just go the conventional route and have separate tapsfor each.
