The installation is actually quite simple, if you are not afraid of water installations.
The supplied instructions, is quite detailed and understandable, except the part with the spring (more on that below).
Overall, the installation takes no more than an hour depending on how you want to install.
The only negative is when the valve supplied with us, that the brass threads at the flattened areas of the feed was not properly trimmed,
so that the screw after a few turns already tilted. But this lies be solved by short machining with a corresponding key file.
Otherwise, the valve lies assemble properly with us on a corner sink, ie the hole cut had not be enlarged and it is also quite straight.
Watching you have even when attaching the spring for the return mechanism, it is felt a meter long
and when they are away from the small cardboard tube to which it is attached with two nails and do not pay attention, she jumps it in a high arc :-).
It is important that one before been attached the spring, until the white boundary piece of plastic (looks like an 8) pulls on the hose,
because if you forget this, the recovery mechanism is not working.
The valve is very high and the outlet can be turned very easily, as well as the water lever.
By height is also very good kettle, pots, buckets or read fill.
However, the tube is not really automatically reset and must be easily traced by hand.
This may also depend on how the valve is installed, that is, whether the tube is free to move under the sink.
All in all I can recommend the fitting date and will make any necessary corrections, if any noteworthy incidents evaluation.
Because of incorrect deburring and the not quite perfect Rückholmechnismus I forgive currently only 4 stars.
