John Asked :
Grohe WC Concealed Cistern - 38422000 I am unable to centre the cistern with my WC. I need to offset to the right by about 200mm. Would I be able to fit a flexible flush pipe to connect cistern to WC?

Answered By QS Team :
Grohe doesn't manufacture a flexible flush pipe. You can use a generic one from a plumbers merchant but this will affect the flush velocity so it may not clear waste.

Grace Asked :
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 another reliable brand with single pipe dual function that we could use. We are limited to a maximum of 100mm for the 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.

Grace Asked :
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
