Hello everyone,
this morning, while the kitchen faucet on my SYSTEMCERAM sink was running, I noticed water coming out near my feet. The water is leaking out at the base of the sink, sideways from the spout. After watching a YouTube video, I’ve been trying for over an hour to loosen the hollow screw. Because it’s so tight, I’m currently using a pair of flat chisels and a 12mm (1/2 inch) open-ended wrench as a lever. When I turn the drain fitting below, only that part moves, but the hollow screw does not turn. Instead, the sleeve thread inside the plastic drain rotates with the hollow screw. It seems to me that the metal internal thread sleeve inside the plastic is spinning along. Is there any way to remove the strainer and the lower part of the spout?
Best regards, ronfruehling

Hello everyone,
reporting partial completion. Ordered a new set via eBay for €24.90 (3 1/2 inches) including the complete drain with eccentric connector; hardware stores unfortunately closed since 2:00 PM. Wire cutters proved very useful. Simply cut off a bit of the plastic thread, then separated the three plastic ribs. I would have preferred to dismantle it without damage, but didn’t see a way to do so.

Hello everyone,
for the sake of completeness, here is the most likely reason for the leak.

The seal under the sink is about 10mm (0.4 inches) too small in diameter. The kitchen was delivered complete and installed by kitchen fitters. The seal held more or less poorly for 8 years, then it became hardened, and eventually, the failure occurred as expected. In the second photo, I deliberately moved the seal to the inner edge of the white plastic spout to illustrate the issue.
