Have the part only ordered because I have no alternative. For Grohe Euro Smart me no other product as a replacement cartridge is known. That part is really expensive. His predecessors have held about 3 or 4 years under normal use in 2-person household. Let's see how that with these cartridges is. But can not really imagine that Grohe has improved the quality noticeable to me. All predecessors had had the problem that the above leaked Mischhebel water. What you actually installed expensive ceramic sealing discs, when the cartridge is leaking itself after 3 years? Then it would have done also cheap rubber grommets. Otherwise, the function was good, so smooth. Positive I would like to emphasize that the cartridges are very quiet.
The scope of supply: The 3 seals for openings on the bottom are included. Should also procure you look 1. a socket wrench into the appropriate length and with extra thin wall (available as an accessory from Grohe in stores, of course, expensive) and 2. a small tube fitting grease, which is thinly applying the rubber seals before mounting ,
So, a star deduction for the price and a star deduction for the poor durability of the product.
