    Water softening system newly installed in my building.

    What is the concern with softened water and heart disease? Is it only
    for the potassium salt used to soften the water, or something more
    complex.

    Zee

  2. Zee,,,water softeners work by exchanging calcium and magnesium ions..the
    hard water minerals..with sodium ions...thus the water is higher in
    sodium...a problem with anyone with high blood pressure..or who retains
    water when exposed to excess salt..

    potassium is not a problem....it is not removed,,nor added with a water
    softener..

    actually you could install a reverse osmosis unit under your kitchen
    sink...to remove the extra salt...or simply NOT drink the softened water if
    salt is an issue with you...rather than the expense of buying bottled
    water...buy a Brita filtering pitcher...they are reasonable and only need a
    new filter every three months..

    your laundry..and your hair..on the other hand ..will LOVE the soft water...

    many folks drink softened water without problem.......

    good luck..

  3. we have soft water on the hot water tank only...... too easy to plumb it
    that way

    and we have an RO water system for those that don't want ANY of the
    minerals.......

    It is if you use potassium salts, instead of sodium chloride.

    If they use standard softener salt (NaCl) it's not an issue, but there is an
    increase in sodium equal to the amount of other minerals displaced. You
    will not be able to taste it even if the water is relatively hard. In
    theory, you are not supposed to use it for watering plants and a few other
    things, but in reality, it's not likely to make a difference. If they do
    use potassium, you can figure out how much will be added to the water supply
    by taking a sample of your tap water in for testing. It would have to be
    water that was not softened. Then when they test for grains of hardness,
    you can figure out how much potassium will be added.

    Generally, sodium chloride is used for water softeners because it's much
    cheaper.

    The calcium and magnesium cations are replaced with sodium cations
    And the calcium and magnesium are lost as precipates.
    Or the water is soften through the use of ion exchange resins which
    remove both cation and anions.

    The potassium cation (K+) forms soluble salts hence K+ isn't removed

    The calcium and magnesium cations are replaced with sodium cations

    Right.

    Quoted message said:

    And the calcium and magnesium are lost as precipates.

    Wrong. Well, not quite wrong. There is a method for extremely hard water
    in which calcium is *added* at elevated pH to force the formation of insoluble
    calcium carbonate. Boiling helps too. But this method isn't used in home
    central systems, and it doesn't add sodium ions.

    Quoted message said:

    Or the water is soften through the use of ion exchange resins which
    remove both cation and anions.

    Sort of right. Anions exchange resins are almost never used in household
    water softening systems, nor are resins that replace all cations with H+
    used. Commonly it's a cation exchange resin that replaces Ca and Mg with
    Na. Periodically you flush the system with salt water to remove the Ca and
    Mg by replacing them with Na. No precipitates - that would ruin your resins.
    The Ca and Mg go down the drain during the purge.

    You can buy small water stills, or reverse osmosis units or specialized
    ion exchangers to produce very pure water for special purposes at home,
    e.g. watering orchids or breeding aquarium fish native to rain forests,
    but these systems are far too expensive and require too much maintenance
    for a home central system, where the purpose is mainly to keep soaps from
    precipitating as calcium salts. These almost invariably use a cation
    exchange resin that replaces Ca and Mg with Na, and is regenerated with
    salt.

    As has been pointed out, central systems are usually put only on the hot
    water side of the system, where the benefit is the greatest, both in
    providing softened wash water, and reducing precipitation of insoluble
    carbonates in the pipes.

    Labs mostly use a combination of RO and resin deionization to produce very
    pure water these days. It comes out the tap labelled "distilled water".

    Quoted message said:

    The potassium cation (K+) forms soluble salts hence K+ isn't removed
    by the old water softening process.

    True but irrelevant. IIRC, that old method was mostly used to soften
    extremely hard water a little for industrial processes and steam engine
    boilers, mainly to prevent clogging of pipes with insoluble carbonates.

    Water softening technology isn't a real important issue in academic chemistry
    programs. They concentrate on theory, not minor bits of technology.

    It may be an honest question from someone who wants to know. A mostly wrong

    their building. Idiot.

    The Dog didn't go to University or Junior College. If you put yourself up
    as a shining product of the education system, it looks like the Dog made the
    right choice. Although, perhaps, a lack of raw intellectual horsepower
    limited your potential. Even in a system that embraces any moron. The Dog
    opines that the current higher education system is wasted on the vast
    majority of intellectually ungifted journeymen who couldn't survive the
    higher standards of a few decades ago.

    Hey stoopid, you don't know your ass from the top of your head on this
    topic. Anyone who did would be familiar with the use of Potassium salts in
    ion-exchange units. My question to hawki63 was rhetorical but inoffensive.

    It has been 30 years since I'd given this any thought and

    Your reproof will keep me humble for a day or two.
    Since I try to be specific in my postings, rather than
    just blowing smoke, I am on occasion specifically and clearly wrong.
    Given the volume of my posting, it not surprising that I exposed
    a gap in my understanding. The worst of it and the best of it is that
    the topic was so close to home. You've surely saved me real life
    embarrassment versus embarrassment of my alter ego here on the Usenet.
    Still on balance my posting history is better than that of Happy Dog even
    considering my error or errors.

    So I request that you hang around and post something interesting,
    instructive,
    and specific.

    Best Wishes and
    Somewhat Humbly.............William Noyes

    Are we talking about arterial plaques here? I think the evidence that

    Ironically, magnesium may well be good for your heart, so removing it
    might not be a great idea, except that water is not typically a major
    source of most minerals (there are exceptions, like fluoride).

    The concern is increased Sodium intake. Not a consideration in your case
    since your water is softened with Potassium (Chloride).

    Lack of Calcium. But there are many other sources of Calcium than tap
    water. And tap water varies quite a bit in dissolved mineral content.

    However there is nothing I can do about what has been done in my
    "home". Now I am trying to find out what my safest, least expensive
    alternative is for cooking and drinking water. I am not allowed to put
    anything on the plumbing and Brita and similar filters will not correct
    the softening.

    I am not concerned about my calcium intake. There is no osteoporosis in
    my family.

    However there is nothing I can do about what has been done in my
    "home". Now I am trying to find out what my safest, least expensive
    alternative is for cooking and drinking water. I am not allowed to put
    anything on the plumbing and Brita and similar filters will not correct
    the softening.

    I am not concerned about my calcium intake. There is no osteoporosis in
    my family.

    Just for you, Zee, I've just spent a little time in PubMed, trying to
    find out the answer to your question. Some studies find a slightly
    elevated risk of coronary heart disease due to soft water. Some do
    not. There's a group in Taiwan that seems to want to associate soft
    water with everything from pancreatic cancer to heart disease, but a
    2004 study in Japan found no relation between CHD and water hardness.

    Even if there is an effect, it appears to be due to the lower levels
    of magnesium and calcium in the water. If this worries you, take
    a calcium/magnesium supplement. That ought to do it. (I do that
    myself because magnesium deficiency is remarkably common and there is
    some history of heart disease in my family.)

    I'm looking into getting a water softener, but the plumbing in my
    condo is not well-suited to installing one.

    Correction: it's the *decrease* in calcium that causes the arterial

    Maybe. On the other hand, it's the removal of magnesium and calcium
    that gets rid of the scaling on the inside of your water pipes.
