A darning needle is one approach - jab it into the rubber and hook

A scalpel or craft knife with long blade is another way and you can
easily jab the Oring but take care with this way.

Thanks for that!

I replaced the cartridge (the customer had ordered the cartridge
anyway, and the O ring came with it). Didn't replace the O ring.

The problem we were trying to resolve was fixed without the O ring,
this being a shower that continued to drip long after the shower had
been turned off.

I guess I was surprised - I thought it might have been the 10p O ring
rather than the 100 quid cartridge.
