Bought the siphon for my new sink. Because of the two pools and the piping under the sink was the end of the pipe system the sink already very close to the wall and just in front of the opening in the wall. No matter how I twisted and turned the thing, I could not accommodate the flexible tube, also not reduced. Then had to use the pipe to the wall and the knee of the old sink, which then has to work, but in the old knee was the connection for the dishwasher, so I had to siphon from here make both connections tight, although they physically better suited. .. Could so effectively only the pipe and locks use, for something expensive.
But maybe that's for another rinse differently and Felxrohr brings an advantage.
So look before only if the connection of the sink to the wall is close (in my case about 15cm) and is exactly in front of the wall opening, then it will be difficult ...
