Hello, in our recently purchased house, the tap water tastes musty/chlorine-like! I started investigating the cause and it seems to be due to the Grünbeck water softener system. As soon as water from the softener is mixed in, the water no longer tastes normal! I have read in various forums that this problem occurs quite often with these systems, and I wanted to ask if anyone here has a solution for this issue? I tried temporarily deactivating the chlorine cell, as I read this might help, but it didn’t solve the problem. Tomorrow, I plan to disconnect the system, remove the salt, and clean everything! I would also like to disinfect the system if possible. If yes, what should I use? If nothing helps, it will be removed!

I don’t follow. Why "as soon as"? Basically, a system like that always works that way. Or did you simply compare the taste of raw water with treated water?

That’s exactly what the chlorination cell is for—to disinfect the resin bed during each regeneration. Basically, it’s also possible to add chlorine dioxide to the salt, but I wouldn’t recommend that.

Cleaning the brine lance can’t hurt. But basically, anything beyond that is a job for the factory service department.

Call the factory customer service (VWO); they can adjust the chlorination. This is probably because the water supplier also chlorinates the water.

We had the same issue with the Grünbeck (SQ21), and since they adjusted it, the problem has disappeared. According to drinking water regulations, the systems should actually be serviced once a year anyway.

I would advise against skipping water softening because eventually all appliances (dishwasher, washing machine, etc.) will scale up, which will become the next cost factor.

You can simply turn off the softened water at the mixing valve, then only untreated water flows!

For that reason, I deactivated the chlorine cell, but it still tastes off! So I switched it back on!

I’ll look into it today—who knows when it was last serviced! Maybe the chlorine cell isn’t working at all!

Deactivating the chlorine cell is not a solution either. According to water regulations, it should be disinfected once a year (just like you take a car for servicing), but unfortunately, very few people actually do this.

In my case, it was the drain that smelled musty because of the water. I gave it a thorough cleaning, and since then, it has been fine.

We have very hard tap water in our residential area. The lime content in the water is not harmful to health, quite the opposite. That’s why we don’t buy bottled water and only drink tap water. The coffee machine is descaled every 4 weeks, the dishwasher as well, and the washing machine has been running for 10 years without any descaler. And it really isn’t any extra work.

I then wonder how people come up with the idea that they need a water softener system. Because it’s trendy and there is extra money to spend? Whenever I see the word chlorine associated with drinking water... 😳
I would uninstall it again. Of course, that’s difficult if you have already paid for it.
