Grohe 38422000 concealed cistern Hello, l am interested in the above Grohe cistern to fit within bathroom furniture but unfortunately all the Grohe dual flush pneumatic plates are too large for panel sections on furniture (including S range), is the another reliable brand with single pipe dual function that we could use. We are limited to a maximum of 100mm for actuator. Thanks Grace

Answered By QS Team :
If the flush plate is too large then you will need to use a button such as 38771000 . You will need to leave a removable panel to the cistern for maintenance.

Grohe 38422000. We have this fitted last year and all is working well. We have now received replacement front panels for the units and have realised that the Skate cosmopolitan 38732000 dual flush plate is too large for the flat sections of the panels. The dummy draw panel has a 144mm high flat section, whilst an adjacent vertical panel has a 127mm wide flat section. would you stock a Grohe dual flush (single pipe) that would fit within the flat sections or perhaps another good brand. Hope you can help. Regards Grace

Answered By QS Team :
You can use the 38771000 button

Is the Grohe flush plate skate 38505 compatible with the Grohe 38422 concealed cistern?

Answered By QS Team :
Unfortunately, these aren’t compatible, as the 38422000 will only take horizontal flush plates.

Was this answer helpful? Yes - No

does this come with a flush plate? Will it connect to Britton Cube S20 Back To Wall WC Pan and Carbamide Soft Close Seat?

Answered By QS Team :
We can confirm that the 38422000 does not come with a flush plate, this would need to be purchased separately, this should fit any standard back to wall pan WC.
