How do you tell the difference between a 47364 and a 12433 Aquadimmer Diverter/flow cartridge?
These are common cartridges within Grohe Dual outlet showers.
Other than identifying your shower here, you can also compare the rear configuration of the diverter cartridge.
First, remove the cartridge from the shower
If the fat pin is on the right hand side and the long opening is on the top, this is the Grohe 47364 Aquadimmer Cartridge
If the fat pin is on the left and the long opening is on the top, as above, this is the Grohe 12433 Aquadimmer Cartridge.
Of course, if you need more assistance please contact us or see our article Finding your shower or part (including identification tips and support).
