A two hand lavatory, quarter-turn faucet which we bought new four years ago has a leak on the cold water side. The supplier, Signature Hardware, promptly sent us two new cartridges (one for each side). I expected an easy fix: turn off water, remove handle, remove keeper, remove cartridge, replace cartridge, etc.
I could not get the original cartridge out- tried repeatedly, but it just wouldn't budge. I checked to make sure I was turning in the correct direction, used a flashlight and mirror to check for hidden keepers, could not figure it out- please help.
Thanks very much,
