Agreed, and I'll add that it's critical to have the water tested before you
propose a treatment strategy.&nbsp; Almost all softeners will benefit from a
sediment prefilter (anything from a simple 4x10 cartridge system to a
multi-stage mixed media system with backflush.)&nbsp; Small amounts of iron can
be removed by a softener, but will require some minor tweaks to the standard
setup:&nbsp; You can have Turbulator distribution tubes installed in the tanks,
which will agitate the media more vigorously during regen and help kick up the
(heavier) precipitated iron particles.&nbsp; Then toss a cup of powdered citric
acid into the brine tank every few months (lowers the pH of the brine,
increasing iron solubility.)&nbsp; Specialized resins are available for all
sorts of issues.<br>
<br>
We are about to try a completely different method of dealing with scale based
on a ceramic media with a nanoprofiled surface which causes the calcium and
magnesium ions to form microscopic crystals, thus preventing their adhesion to
surfaces.&nbsp; They have some convincing case studies with 4,000 PPM feed
water, and (unlike softened water) there would be no compatibility issues with
stainless HX surfaces.<br>
