Watercat Cube - Descaling system recommendation / experiences?

In Germany, there is no law that prescribes that only DVGW certified descaling systems may be installed. It is solely the consumer's decision. The DVGW rulebook is not a government body!!! The DVGW = Deutsche Vereinigung des Gas und Wasserfaches E.V inspects water softening systems and gas systems on behalf of the manufacturer for a testing fee. On the board are Grünbeck, bwt and Judo... Hello lobby! So let's look at this again: DVGW certified descaling systems must have a backflow preventer, germ protection and a control with forced regeneration. In all domestic water installations, according to DIN1988 and DIN EN1717, a free-flow valve with backflow preventer must be installed. This is TODAY standard in every house colloquially known as a dirt filter. Therefore, a DVGW tested softening system is NOT and in NO WAY necessary. The installation of a NON DVGW tested water softening system fully complies with the regulations thanks to the pipe and system separators according to DIN EN1717. And our conclusion, as has often been said here: Everyone as they see fit. P. S.: Only experts can inspect... true! Wrong word. In Bavaria this is called Dipferlscheißerei

On the board are Grünbeck, bwt and Judo... Hello lobby!

The DVGW is, after all, an industry association; it's completely clear that association members sit on the board. Who else would it be? I don't see what is lobbyism about that. Influence on political decisions is not exerted here after all.

In Germany, there is no law that requires only DVGW-certified descaling systems to be installed.

That applies to the current version of the AVBWasserV. Before the European harmonization of the regulation, however, a DIN-DVGW certificate was explicitly required here. I don't have a synapse at hand right now, but I'm not sure that the explicit requirement of a DIN-DVGW certificate dates back more than 7 years.

Hello everyone, and first of all, many thanks to the forum!! By doing a bit of 'skimming' you already learn quite a lot here. I also have a question about the topic of water softening systems, but I don’t want to start a new thread about it right away (I didn’t find anything in the search function, but maybe also due to lack of technical terms...).

Question: Does it make sense to connect the water softening system only to selected pipes? Specifically, we want to produce hot water with a [BWWP], meaning it should be around 23 degrees. To protect the device, I would put a water softening system in front of it. The same goes for the dishwasher and washing machine. I would leave the rest of the cold water pipes and toilets as they are. What do the experts say about this idea? That way, you would always have the option to draw 'untreated' water (for tea, etc.)...

Thank you very much in advance!

The acquisition of a descaling system is, in my experience, quite a differentiated matter. In February of this year, I ordered a CM 32 (ion exchanger principle) online directly from Aqmos for my detached house and had the installation done by the company Pillak from LappersdorfOpf., recommended by Aqmos, for a fixed price of 399 EUR. Shortly after, we had to find out that the water was probably no longer particularly suitable as watering water for some flowers. About 4 weeks after the installation, we had the first flooding in the basement with wastewater from the regeneration process. This mishap repeated itself increasingly frequently in the following months, most recently at intervals of 5 days. The result was a floor covering no longer suitable for anything but the trash, not made of tiles, as well as fittings of the descaling system corroded by the concentrated salt solution and metal cabinet feet.
In a subsequent call to the company Pillak, I received only the brusque response from the entrepreneur: "The system is not to blame for that." Mr. Pillak cancelled a first follow-up appointment at short notice due to an allegedly necessary hospital stay. On the occasion of a second appointment arranged a few days later for 6 p.m., I received a call from Mr. Pillak at around 12:30 p.m. on the same day at my workplace (about 20 km from home) saying he could be on site in half an hour!? Since then, I have heard nothing more from him.
An email to Aqmos with my descriptions and my suspicion that the company Pillak had completely underestimated the drainage capacity of the supply line to the main downpipe through which the regeneration wastewater should flow was answered by Aqmos that this could by no means be the case and I should check whether a siphon, perhaps the main downpipe or a toilet, was clogged. That was finally the last straw for me! I replied to Aqmos that there is no siphon in the installation environment of the system at all, and whether Aqmos was under the impression that my wife and I had been going to the neighbors’ toilet every time for months (since the first flooding).
With a realistic view, one can at most say that it is hardly conceivable that an installation company with a round trip of about 300 km, without prior inspection of the installation site, and possibly like in my case, another hour on its own cost to procure further parts, would take the risk of providing this service (also together with an apprentice, the son of the entrepreneur) for a fixed price of 399 EUR. And that in a time when craftsmen are generally hard to get. This alone already speaks for the quality of the aforementioned company, but also for Aqmos as an intermediary. Unfortunately, this realization came too late for me.
I am willing to give away the system against pickup.
