KCl vs. NaCl

I am concerned that using NaCl in the water softener will shorten the life of my water heater and fixtures due to the salt content in the water. I know that KCl cost ~ 3x more than salt but over the long run will it all equal out (i.e. replacing the water heater and/or fixtures)? Am I being paranoid?

In short the answer to your question is yes.

Both sodium chloride and potassium chloride are "salts".

A better approach is to make sure your softener is proper set up, backwash flow rate is adequate, and softener is set on an efficient salt setting.

Do you have a tank or tankless water heater? What is your source water test results in hardness, TDS and iron? Are you on city water? What kind of softener do you have? Timer/demand? Size?

I have a tank water heater now but when that one craps out I plan on going to a tankless water heater. Hardness is 15 gpg, TDS is about 215 ppm, no iron, on city water, plan on buying a Fleck 7000 (80,000 grains) in the next week or so from affordablewater.us. Debating whether I should pay the extra $60 for the American made 8% softening resin, does it make a difference?

Some individuals with concerns about high blood pressure choose to use the KCL rather than the NaCL to reduce their exposure to sodium.
