Sheila Asked :
I want to buy the following concealed Grohe cistern QS-V81816. Is the flush plate QS-V55842 compatible? Or is QS-V57651 compatible too? If these are not suitable, can you please advise which flush plates will work? I do not need a dual flush and prefer smaller flush plates.

Answered By QS Team :
The 37761000 pushbutton assembly is not compatible with the 38863000 concealed cistern. The 37060000 pushbutton, which is very similar, is compatible. The 38573000 (, Skate flush plate is compatible with the 38863000 cisterns.

Christopher Asked :
Is this compatible with the Grohe 'S' type small flush plates when used with the Small inspection shaft - 40911000 - which is an option, for example with QS-V80673 (OP-101935)? This is not a question about back to the wall pans.

Answered By QS Team :
Unfortunately, this system is not compatible with the small flush plates.
