How to descale at 44* dH

I think we have purposefully found the spot in the area, which really already has very hard water, that has by far the hardest.
If only it hadn’t fitted so well with our jobs and the mother-in-law (far enough away and close enough).

In such an extreme case, I would ignore the 200mg/L limit for sodium and accept the higher salt intake. Water at, for example, 300mg/L is not immediately toxic. It won't do anything to adults, and at-risk groups can switch to bottled water. Besides, it's still healthier than anything that comes from plastic bottles and most "medicinal" waters. And what ends up in children's stomachs during cooking, bathing, and washing is no worse than a small piece of sausage per week.

A high sodium content in water is not recommended for high blood pressure, diabetes, and for young children. Overall, however, it is rather uncritical. If in doubt, I would filter the drinking water separately to reduce the sodium content again.

Just for classification: The recommended daily maximum dose of salt (which is probably significantly exceeded by most) is 6 grams of salt. That corresponds to about 2400 mg of sodium. The influence of the choice of drinking water is therefore somewhere around 20% more or less. Or just two slices of salami.

Clearly, your water is very hard, but it’s not that bad. As drinking water, it is very well suited, and it won’t clog the pipes within 3 years for that reason. Cleaning effort in the bathroom is higher with calcareous water, but that will still be the case after softening as well. Just ask other people in the supply area how they manage.
