Mains water in Cattolica
In Cattolica mains water ranged from 20 to 45 French degrees depending on the period (readings from 2015 to 2024), and in the latest half-year it was 45: it is hard water. Dry residue is around 728 mg/l.

Above 35 French degrees, scale on boilers, washing machines, dishwashers and shower heads is the rule, not the exception: here, alongside the treatment of the water you drink, a water softener is worth considering. Dry residue is high here: if you want lighter water, reverse osmosis is the way.
There is no legal limit for hardness in Italy: Legislative Decree 18/2023 sets none, while the previous Decree 31/2001 recommended 15 to 50 French degrees. For a domestic softener it is advisable not to go below 15.
