Question 1

Does a softener reduce TDS?

Accepted Answer

No. It exchanges hardness for sodium, so the dissolved solids figure stays broadly the same. If you need lower TDS you need RO or demineralisation.

Question 2

Is softened water safe to drink?

Accepted Answer

Softening raises the sodium content in proportion to the hardness removed. For drinking water it is usual to leave a separate unsoftened or RO-treated line.

Question 3

How much salt will it use?

Accepted Answer

It depends on resin volume and regeneration frequency, which follow from hardness and daily throughput. Volume-based regeneration cuts consumption noticeably compared with a timer.
