ᐅ Watercat Cube – Recommendation / Experiences with Water Softening Systems?

Hello everyone,

In our future house, the water hardness is between 23 and 25 dH. I have spoken with some people from the new development area, and many are having a water softening system installed directly. I have done some research online, but honestly, I am a bit unsure. Many people strongly recommend salt-based systems, but what about something like a Watercat Cube? Does a system like that work with my water hardness?

If you want to drink only the water coming from your tap, this is the recommended guideline... If you use it only for cooking and washing, you can go even lower. Sodium is not toxic.

Why is this not a problem when cooking?

What should I do now? Buy a system and then just reduce to 18° dH?

You don’t reduce to 18° dH, but rather by 18° dH. That would bring you down to 11° dH, which would be fine.

As long as it’s just the pasta water, which is discarded after cooking, the amount of sodium doesn’t really matter. The same goes for showering, etc. However, it’s probably best not to drink it.
Whether this is allowed or not, I can’t say.

Oh, of course, I must have made some mistake in my thinking.

What would be the salt consumption of the Grünbeck SC18 when reducing by 18° dH?

According to the data sheet:
0.039 kg of salt per m³ and °dH.
If you reduce by 18°dH, you get a salt consumption of 0.039 * 18 = 0.7 kg per 1 m³ of treated water.

The same applies for wastewater:
3 liters of wastewater per m³ and °dH
-> 3 * 18 = 54 liters of wastewater per 1 m³ of treated water.

You will need to know or estimate your annual water consumption yourself.
