The enclosed, and the special Perlstrahlkopf Ankupplungsteil for Gardenasystem sit safe and drip-free and are super fast (de) mountable.
If you have not noticed that free "hole" in the red tab is the tool to tighten or loosen the Perlstrahlkopf.
Ensure you have at any rate it - and this is especially true if you hose upward directed / pulls - that the house enough water pressure is available, so that no backflow / may arise -sog. But actually this is true in principle for each tube or secondary connection to a drinking water pipe.
Now uses for this are available in the apartment but so many, the flexible hose is too short. However, I use this adapter primarily in connection with a hose to flush out, permanently mounted in or on the wall sewage pipes from time to time even with hot tap water. Works great, especially since I cut around the introduced hose end and have closed with an aluminum rivet so that a pressure-intensive and fan-like jet of water is produced.
always thrilled by this adapter and therefore, sure, full 5 stars Amazon!
Note .:
After more modern taps often have a slanted seated Perlatorstrahlkopf with M24 or M22 IG AG, is so at least in my Grohe, at these taps the Perlatorstrahlkopf of Gardena too short, ie, you can not put the coupling member. If there are no other taps for Dodge is available, here you can easily with an additional extension between Hahn and Gardena system of (depending on the required length and Perlatoranschlussgewinde) eg M24 thread x M24 IG / AG M24 x M22 or M22 IG AG * x M22 AG help.
* Here you have additionally the re-lengthening M22 / M24 intermediate ring (of Gardena supplied) are used.
(IG = female thread - AG = external thread)
