Hello: I’m a little confused by the water hardness of 50 ppm. Is that the calcium hardness left in the water after softening? What’s the hardness before softening?
To mess with Randy’s numbers a bit, it should be 60 to 120 ppm of “hardness” left in the water after softening according to the National Association of Corrosion Engineers, (NACE). I’d soften a little less if possible as oversoftened water can have the anode down to a bare wire in six months 😯
