This question is regarding Trevi 1/2"" DX 1/4 Turn Flow Cartridge, Anti Clockwise Close

Cartridges on A3000

Can I ask what socket size is needed to remove the cartridges? (my model is the recessed version) I've seen a few instances of the rear of the old cartridges getting stuck when unscrewed (see youtube) what is the best way to remove without damaging the casing?

A 22mm box spanner will do the job.

If the rear gets stuck, a crochet hook will remove it.
