How do I get my faucet handle off?
You need to remove the piece of bell shaped trim surrounding the cartridge. There is very likely a large nut under there. To avoid scratching i usually wrap the lowest part of this trim with 3-4 winds of masking tape, then undo with water pump pliers. These spread the load nicely. You maybe lucky and get the leaky cartridge first, if not at least you know how to do it,so the next one will be easier.
