Anyone who wants to use the set of a Waschbeckensiphon, is certainly happy with it. The reviews below are the fault no clamps with screws enclosed understandable but unfounded in view of the low price. The enclosed clamps are tight enough around the hose to be mounted securely and tightly. If you want more comfort during assembly can get screw clamps for a few euros at the hardware store.
Ultimately, the manufacturer has discovered a gap in the market because of the siphon at the moment there is no alternative and to my surprise, neither the hardware store is still available in stores.
Consultation with a gas us has Wasserinstallateur yield the for mounting on a flush-mounted siphon more of a Y adapter with an internal pinch and a reducer on 8mm suitable for the hose of the dryer.
