Keep a softener actually working, rather than discovering months later that it ran out of salt and the limescale came back.
Who it is for
Households with a water softener, particularly in hard water areas.
How to use it
- Record the incoming hardness and what the unit is set to.
- Log every salt top-up with the date.
- Test the softened hardness periodically and record it.
- Note servicing and any resin or valve work.
