Can I drink softened water?

Yes.

There is a small amount of sodium in softened water due to the softening process, to put this into perspective there is more sodium in a glass of milk than in a glass of softened water.

If you live in a very hard water area, where the water hardness is over 400ppm you should have a separate mains water tap in the house.

The only times we advise against drinking softened water is if you are on a prescribed low sodium diet or when making up baby formula.
