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:

Hello,
what diameter does the hole have?

The hole has a diameter of 35 mm (1.4 inches). The white plastic ring, which holds the seal, is located inside the hole.

Here are a few pictures:

Could it be that the white ring is sitting on top? Because in the first picture, I still see a smaller hole, or is that just an illusion?

No, the white ring fits completely INSIDE the hole. According to the installation manual, the diameter of the ring (33.5 mm (1.32 inches)) is smaller than the diameter of the basin hole (35 mm (1.38 inches)). I would definitely notice if the ring was stuck on top – it is made of hard plastic. The gasket is the problematic factor. It is simply much too thick.

Your gasket is simply much too tall

I can’t imagine that, since, as shown, everything fits inside the bore. Did you place the plate (referred to as 5.3 in the description) on before the crescent-shaped plate (5.5)?
