Over the years a wide variety of designs have been developed, which I indirectly as a statement "It was not an optimal design" values. This is also my experience with this mixer taps series: Mr. Starck has thus perhaps what created for the Museum of Modern Arts, Grohe but had thus no opportunity to develop a long-life mixer. While the operating lever normal Einhebelmischbatterien usually bell-shaped inside out over the mixer cartridge and thus protecting against dirt and water, the whole Siff flows at the Starck-fittings for basin and bidet right in there. Under the cover collects a yucky goo that you could not even remove in the first versions, since the upper end cap is pressure tight fitting for the mixer cartridge simultaneously. If you screw this cap under water pressure from, should one meet all the innards of the mixer and one has after a 2-fontänigen Zimmerspringbrunnen - one hot, one cold. Later there was a separate screw and only plugged embellisher. The can be removed for cleaning of the upper portion of the mixer.
In Set 94004000 to find fittings for both basic body with internal and with external thread. Furthermore, of course, the mixer cartridge, the rubber stopper to seal against the water connections, the two there inserted springs, an adapter to adjust the mixer cartridge in the older mixer body in diameter, a small O-ring for sealing the cartridge upper side against the top screw connection (not shown in some representations of the manual), a large O-ring for sealing the mixer tap body against the top screw, the quill-handle, the grub screw to fasten the handle along with Allen key, the decorative cap for clipping and a universal tool for solving / Verschauben the valve parts.
One does not need the whole set, eg when only the cartridge is defective - there is formal cheaper solutions. But it is helpful to have everything on hand when you first split an Axor Starck mixer and do not know what to expect. O-rings, for example, should always be replaced with, for some reason you need the bodies Dick adapter - everything is included.
To review: the spare part 94004000 meets all demands that the repair job - so really 5 star. The overall design of the mixer is carried out but in my view only for design reasons. Here is probably true quite often "give a designer a commodity and it is no longer usable after". Here it is: necessary high risk of corrosion and permanent Versiffung through standing soapy water in the faucet, regular "internal cleansing" of the decorative cap, "Closed" position ambiguous mechanically recognizable (my elderly parents can be like to accidentally tap slightly open). A "multi-sham-as his" product. For me, so at most only 1 star. For the spare part can but nothing.
