So I was forewarned by the reviews that were already inside. But thought can not be yes. At the same time I've ordered a new shower head from Grohe. Connected and it is only rausgeschossen the water in the shower head connection hose. Connected the Old Hose. Everything tight. Specifically looked at the tube. On both sides no seal. Then I have the seals taken out of the old hose and into the new. Lo and behold. Sealing. And it was no seal at shower head while because I have already read here. I will not send the item back now because I the old seals nor did but the kanns not be. Grohe want as easily save and thinks the customers are already set. But he is so how to buy the basic principle the hose useless.
