In DIY stores no cartridges are sold, but at Hornbach they offered me at least to be able to order a new - I just did not know, unfortunately, the manufacturer of the faucet but had thereby only the broken cartridge.
So I went to various plumbing specialist markets, where they had laughed at me. It would anyway be no cartridges for Baumarkt-taps. And the broken with which to compare in stock, if one is identical, you need not even try.
Anyway, I have here then bought - get a day later and it fits!
Priced super when I consider what the cost in retail warehouses so.
The important thing is just to compare all dimensions. If you google for Sanifri 470010372, to quickly find a graph where all dimensions are specified. This I have compared. Although this cartridge has below 3 round holes and the old just a round and 2 oval holes ... but the faucet of Interior also has 3 round holes.
Fits So, priced super and they do what they should. She goes only slightly heavier than the old, but not until just incorporated.
So: old to expand, distances accurately measure it (before googling for graphics) and the order here. Saves a lot of money.
