Replacement Cartridges for manual Grohe mixers

Where a mixer tap has separate hot and cold controls the two cartridges will be required.  In general the hot cartridge will be clockwise turn for off and vice versa.

For a single control (usually a  lever) manual mixer then only one cartridge is in use.

Most cartridges are based upon ceramic disc components requiring only a part turn to be fully on.

Replacement handles are also available for most models.
