ᐅ Inlet pipe for water flush to the toilet is completely clogged with limescale buildup!

Hello everyone,
I am looking for an affordable and neat solution to repair a new concealed (in-wall) toilet cistern.
… and first, a bit about the building conditions.
We moved into our detached house almost 25 years ago. Water hardness is 24 dH. During 2023, the water flow when flushing the toilet gradually decreased. In late autumn, I spoke to the plumber, who said the problem was with the toilet, as it was heavily scaled under the toilet rim and needed to be replaced. However, the toilet had already been replaced once before. I insisted that he should first check the concealed cistern.
Since now almost no water is flowing for flushing, the plumber finally checked the setup last Friday. He removed the toilet (which is only slightly scaled).
Cause: the water supply pipe to the cistern behind the wall is completely scaled, with fresh water only passing through a tiny opening to flush the toilet.
Removing the limescale from the pipe was not possible – it is rock solid.
We want to apply descaling agent through the cistern into the pipe tomorrow and let it work for several days.
What should we do if the limescale does not dissolve?
Are there any solutions available?
The supply pipe and the concealed cistern are entirely installed inside a stud wall, similar to what is shown in the attached file.
Does any expert know a clean, inexpensive solution?
Thanks in advance.
Best regards,
Luise Müller

We have a magnetic lime converter installed and have been satisfied with it since then – opinions may vary, and that’s up to everyone individually.
Just Google the device; the website is very informative. No. You cannot be “divided” on this. Anything without a single scientific proof (because there cannot be any) and without any certification or approval from recognized institutions like DVGW is not worth the money. This is the unanimous expert opinion. Sorry.

It has been working for us for many years.
Clearly: the lime scale is not GONE – it is still there. However, when I see that
- for example, I can simply wipe away lime stains in the bathtub during cleaning without much use of chemicals,
- the lime deposits in the kettle eventually flake off because they can no longer build up very thickly (and I can easily wipe them off the walls with a cloth), and
- the pipes have remained practically clean over the years (we recently installed the heat pump, which also involved changing the water piping),
then I fully acknowledge your expert OPINION.

For this reason, the magnetic descaler has no certifications, as no company or testing organization can confirm its verifiable (!) effect.Enjoy it if it makes you feel good. The proven effect is just as measurable as with homeopathic remedies (although at least there the placebo effect is present).

But just as a side note – so-called magic devices simply don’t receive certification.
And once again: These devices have been tested by various institutes. Not a single one has been able to confirm their effectiveness. Feel free to keep believing in it, but scientifically, it’s not supported.
And if you don’t want chemicals in your water, you can also buy devices that actually work and operate without chemicals.
