The (craftsmen) Life can be so easy

The original pipes for the new vanity I had to saw fit and the tight connection to the drain valve was a challenge (for me anyway). Then briefly the drawer hang in wall cabinet at the end and "ta da", the siphon is 0.5 cm in the way. What a fumble.

With this wonderful part simply screwed in the end of the wall and the other with the sealing and voila ready and dense and wonderful. If I had known only once before, I would have saved me the previous annoyances.
Clear acts the part is not so high and when it would clearly visible hanging, I would clearly have recourse to the more stable and high-quality tube system. But behind a cupboard hidden, the first choice.

Via the longevity of course nothing to be said, but what there already can go big break.
