Dear Carol: Yes you can condition your water at specific outlets, with magnetics. But it's just as easy and cost effective to treat all the water in your home. Magnetohydrodynamics doesn't soften water, it makes water behave soft. There are no chemicals, salt or electricity required, and the magnets are warranteed forever. If you'd like to know more, please e-mail me or call me at 800 851 9891. Sincerely, Brian Wood.
