How do I mend a single levermono mixer kitchen tap?

Very useful point in the question about using an allen key to get the top off a single lever mixer tap that was very stiff to actuate. Simply loosened off the retaining nut, inside the removable top trim, about half a turn and all sorted.

my single mono mixer tap stopped working but is not stiff. i took off the lever then uncsrewed the top trim which reveals a retaining nut. when this is removed the single unit cassete inside is revealed. i had a broken part inside and after much searching have found a supplier, Lunns plumbing supplies. however the part i need costs more than the original tap and may buy another tap from ebay to use for spares. hope this helps. jean
