Technical information
To ensure proper operation, keep the salt level in the brine tank above the water level at all times. We recommend keeping the tank around two-thirds full of salt. How often you need to add salt depends on water hardness and daily consumption, but for most homes, it’s enough to check it every 2 to 4 weeks.
Important: Never let the salt run out completely, as it may stop the regeneration process and reduce the efficiency of water softening.

FAQ
-
What is the Core softener and what is it used for?
The Core is a compact water softener for tap water, designed to remove hardness that cause limescale in pipes and household appliances. It protects your home’s plumbing system and extends the life of equipment like washing machines, boilers, and dishwashers.
-
Is softened water safe to drink?
Yes. Softened water has reduced hardness, which improves comfort and equipment protection, but remains safe for drinking. It contains fewer calcium and magnesium ions, but no harmful substances are added or introduced.
-
How often do I need to add salt to the Core softener?
Salt should always be maintained above the water level in the brine tank — ideally, it should fill about 2/3 of the tank volume. The exact frequency depends on your water hardness and daily water usage, but for a typical household, this means checking the salt level every 2–4 weeks and refilling as needed. Never let the salt run out completely, as this may interrupt the regeneration process and reduce softening performance.
