As lady_p_gold says, the kitchen tap is left untouched, but actually the water doesn't taste salty. The water does have sodium in it so is not recommended for childen, the elderly or those at risk of heart disease, but you can certainly use it to clean your teeth in!
I am now addicted to my osmosis softener (second only to the dishwasher) and wouldn't be without one again.
If you do get a softener and have an outside tap, do try to get the outside tap not connected to the softener. as it does cost money (not a lot) to soften water and you wouldn't want to waste it in the garden!
