After> 10 years our Kludi fitting has become petulant = lever very difficult to operate and they are water voluntarily they = drips out above. Annoying and long term is not good, so exchange. What's the matter so as a substitute? Safe in the department in the local hardware store a good choice. Yeah, actually there! From design to "the actual art-or ...", from cheap (about 25) to> 200, and "virtually" is represented. Oh yes, you can buy house brands. And - brand manufacturers also: Grohe. Now it gets difficult, because many faucets have wg. (Partially above) fell out reasons ;-) from the immediate choice. Was looking for: "Easy-to-install-without Markup for" affordable and quality. Result: Grohe with this fitting. But unfortunately not in stock :-( (it was the weekend), only in 3 weeks! So back home to petulant cock. Good thing the customer is of age (bad for trade, as it often takes long) and looked up here sometimes. With the result that on Sunday bought fitting on Tuesday was in the house. As WHD without visible defects, the thing was dry.
The installation itself was not a big challenge, a good screwdriver for fitting itself plus one (pre-assembled!) A 10er and 13er end wrench for the feeds. All replaced in approximately half an hour (which was kludi the expansion unfortunately unruly) - something also delighted the home (or the housewife who can do it well).
After about two weeks of experience: the water bubbles without any problems and it silently + just where it should. The operation? The easiest way. And manually flush also of large format parts (pots, casseroles, ...) is now a) again possible and b) much easier.
Let's see how it will be after a long time the focus I do not trust in any case more than 10 years.
