I had the fitting unfortunately send back because it was not to be fixed to a standard pool. After 2h Building I gave up (and I'm not a layman). Reason is a design flaw, after the attachment is forward instead of back. This makes the device very visually beautiful acting tilting forward completely if the man fitting touches a bit firmer. A spacer / adapter ring between valve and basin could possibly help, but this was not designed. I have read the Armature to the hardware store to buy such a ring and have come with a new faucet (80) home. Time that I wanted to save. Too bad about this experience, maybe it will help others.
