ᐅ Sealing Issue with Single-Lever, Single-Hole Washbasin Faucet 01092283

Hello,

I have a problem with installing a single-lever, single-hole washbasin faucet from HANSAMIX (01092283). The pre-assembled base gasket seems to be too thick, because when inserting the faucet, it sits about 3 mm (1/8 inch) above the rubber gasket. Of course, the gasket is meant to provide some spacing to seal the base of the faucet when tightening. But when I attach and tighten the crescent washer, the faucet does not pull down but instead tilts forward toward the basin rather than settling flat and vertical on the mounting surface. This can’t be normal, right?

Is this a design flaw? Given the price and brand, it shouldn’t be an issue. But the gasket is definitely too thick. What do you think, and what would you recommend doing?

Here are some pictures of the described problem:

I can’t imagine that

But it is. The pictures clearly show it.

The plate (part 5.3 – the white plastic piece with the seal) is factory-installed exactly where it is – on the mounting threaded pin at the base of the faucet. My installation sequence from top to bottom:
Faucet > washbasin < crescent washer < fastening nut.

Edit: For those wondering what is meant by “in description 5.3,” here is an additional installation diagram that I unfortunately cannot add to the first one, as the editing period has expired.

Wow... you would think it would be obvious what the problem is, but it’s frustrating me now... I need to check at home if I can find anything in my documents, but it could also be some kind of glitch... 🙂

Or maybe someone else will speak up who has a solution. Off the top of my head, I can’t think of anything else right now...

Thank you, that is really very kind of you!

Maybe the white panel needs to go under the washbasin after all?
At least with ours (not a Hansa faucet), there was also a plastic part between the washbasin and the semicircular bracket.

This is hard to imagine because this component is the seal that prevents water from leaking between the faucet ON the washbasin. Under the basin, there is only the crescent-shaped plate as the counterpart. If you were to follow your suggestion and remove this part, there would be no seal at all, which makes no sense. Furthermore, there is no additional sealing ring included that could serve as an alternative.

With such a low number of fastening parts (only 2), it is really impossible to do anything wrong, since the faucet is fully pre-assembled and the only mounting materials included are the crescent-shaped plate and the nut.

Of course, the gasket still needs to go on top.

I initially installed it the wrong way around on our faucet as well, since it was delivered assembled. When tightening it, I wondered why the metal disc was rubbing against the ceramic. After checking the instructions, I realized that the plastic piece naturally needs to go between the metal crescent and the ceramic.
