ᐅ Water softening system – Calcium and magnesium increase sodium content

Hello everyone,

I have read several posts about water softening systems so far. The following disadvantages have come up repeatedly.

  • By removing calcium and magnesium, the sodium content increases, but too much sodium is not good for health.
  • The pipes can be damaged over time and will eventually need to be replaced. This can supposedly be counteracted with phosphorus, but that also should not be in the tap water.
Can anyone confirm this? Are there possibly other ways to prevent limescale buildup?

If you set the system to an incoming water hardness of 3-5 dh, everything works well!
Good for both your health and the pipes.

You should never soften water to 0 dh!

The salt requirement depends on your incoming water.
We soften from 23 dh to 4 dh and use just under 25 kg (55 lbs) of salt per month. That means salt costs below €10.

I’ve never really looked into the electricity costs. They’re definitely worth the added value!

Oh my goodness! Something’s definitely off here. That’s extreme. We only need 1 to 2 bags per year and soften from 24 to 7 dh.

Then it really seems a bit strange to me!

How often do you renovate your system?

I just have my Grünbeck app open: in October, we used 4,500 liters (1,189 gallons) of softened water and needed 3.3 kilograms (7.3 pounds) of salt for that. We soften from 23 to 4.

@Golfi90 so either you need 40 cubic meters (1,412 cubic feet) of water per month – or your system is not properly adjusted.

The system automatically regenerates, usually once a day in our case. It is a Judosoft.

That’s complete nonsense. The sodium content doesn’t increase that much. If you’re concerned, you can install a separate line to the kitchen without water softening. This is common practice and has a significant advantage: the water tastes much better than softened water.

I would have thought it tastes better; unfortunately, ours is basically none of the tasty ones ☹️

Our system regenerates once a week or after a consumption of 4500 liters (1190 gallons), whichever comes first.

Of course, we also have a relatively large system. I can fill up to 100 kg (220 lbs) of salt into the container...

Does that also make a difference?
