Sealing problem with washbasin single-lever single-hole mixer 01092283

Oh, of course. Here I assume that the manufacturer just wants to protect themselves in case you flood the place, so they cannot be held liable. And if the installer does it, then he’s the one who got messed over. If the fitting is defective, neither the layman nor the professional can be blamed for it. I would take it calmly. Mind you, my personal opinion.

If the fitting is defective, neither the layman nor the specialist can be held responsible.

That's basically how I see it too. However, the manufacturer probably won't provide a replacement if I can't show a plumber's invoice, right? My concerns are specifically about the cartridge. If it breaks, it’s debatable who covers the cost of replacement if I install it myself... I suppose. Do you have any experience to help assess the risk?

You are throwing arguments around here. Let a craftsman come and install the thing. sometimes you just have to spend 50 €.

Hello Hello

No, the plastic ring belongs on top under the fitting.
How soft is the rubber gasket?
Have you tried attaching the fitting using the T-handle?
That way, you could find out if the rubber compresses.

I won't say anything about the warranty and the installer.

how soft is the rubber seal then?

It feels quite stiff to the touch – comparable to the seals of a siphon connection set. So pressing it vertically by hand doesn't really work. It's not as soft as a rubber ring used for insertion.

Have you tried fastening the fitting using a T-handle?

I will tackle that today.

I won't say anything about the matter with the warranty and the installer.

That is actually very important to me. If you have concerns about being pinned down to it, feel free to send me a private message.

Alright....

as a homeowner, you roughly agreed
.....to have all extensions, modifications, and maintenance carried out by an installer approved by the association......
just so you know

For some reason, you did not purchase the fitting from the installer nor commissioned the installation. Now you are struggling with securing the fitting and are worried about a warranty claim. The colleague is supposed to come rushing over now, fix the problem, and be liable for any possible warranty claims.
