A softener is sized on two things: how much hardness it has to remove between regenerations, and the flow it has to deliver. We size resin volume from your hardness and daily water use, then pick a vessel that delivers your peak flow.

FAQs
How is softener capacity calculated?
Soft water per regeneration = resin litres × resin capacity (about 57 g per litre at a standard salt level) ÷ hardness in ppm. The table assumes 300 ppm hardness.
Manual or automatic softener?
Manual is lower cost and suits plants with an operator. Automatic regenerates on a timer or after a set volume, which avoids hard water slipping through.
Does a softener reduce TDS?
No. It swaps hardness for sodium, so TDS stays about the same. Use RO or a DM plant to reduce TDS.
