What to test

  • Sodium
  • Chloride
  • TDS
  • Hardness

What to do next

  • Confirm sodium with a certified lab and compare with chloride and TDS.
  • Review softener settings because ion exchange softeners can add sodium.
  • Use untreated cold water for drinking if it bypasses the softener and is otherwise safe.
  • Consider reverse osmosis for drinking water if sodium reduction is needed.

Common questions

Does a water softener add sodium?

Traditional sodium-based softeners exchange hardness minerals for sodium, so softened water can have higher sodium.

Can reverse osmosis remove sodium?

Reverse osmosis can reduce sodium in drinking water when maintained correctly.
