Cartridge/Valve replacement

[SPReynolds]

Can anyone help with the tool I need for replacing a cartridge/valve in a RAK kitchen mixer tap (hot side) The hexagonal nut to remove the valve is recessed within the tap body and I cannot get an adjustable spanner inside deep enough. I have tried a various metric size box spanner’s but none will grip the hexagonal nut.
Many thanks in advance.

Ha ha ha that is our exact mixer tap, many thanks for the video. I have now successfully removed that chrome casing and can now get at the cartridge.
Many thanks once again.
