14 March 2026
WATER HARDNESS AS STARTING POINT
In Belgium, water hardness varies greatly by region. Antwerp: 15 to 25°f. Brussels and Wallonia: often up to 35°f or more.
AVERAGE CONSUMPTION PER HOUSEHOLD
An average family of 4 uses about 10 to 15 kg of salt per month.
SETTING YOUR SOFTENER CORRECTLY
A poorly set water softener consumes unnecessarily much salt.
