Water softening system 43 dH

Do you think the difference between 43dH and 22dH will be noticeable?

Yes, and in two ways. First, for yourselves, because very hard water is not good for the skin (it becomes dry and cracked). And then, of course, for all the devices that use the water (washing machine, toilet, shower, faucets). If I had such water, I wouldn’t even be asking this question here, but would already be "screwing and connecting" a water softener. Screw the warranty, who replaces your dishwasher and washing machine after 5 years?

These are just old wives' tales. No dishwasher or washing machine breaks down because of hard water. Every detergent softens the water, and every dishwasher and dishwashing detergent contains salt. Just because you soften the water doesn't mean you have soft water. 22dH is still very hard. The same problems remain. In return, you then have even less healthy water, which can be dangerous for infants, regular maintenance, refilling 10-20kg of salt per month, frequent discolored deposits, an additional risk of contaminated drinking water in the house, etc. You have to want all that for the money. And it doesn't taste any better either...
