Hi Darran,

Which brand is the manufacturer? Grohe? Geberit? Althou most brands work with similar systems..

If you wish to replace the concealed system then you will need to uncover it which means breaking the tiles and the drywall construction in most cases. Unless you have some other way of accessing the system behind the wall you will have to break the covering and repair it after.
