Does anybody know where I can get a replacement tap valve that has a
cone shaped washer? The tap in question doesn't have any identifying
marks, but looks very similar to the Librio Profile Monobloc Basin
Mixer listed on PlumbWorld:

The standard B&Q replacement valve has a flat washer (ie it doesn't
fit into the reverse cone shaped seat in the tap), and is also
slightly too long (ie it can't be opened far enough)
