The cold faucet is leaking, and I am trying to repair it by replacing the valve cartridge. However, for the love of god, I can't find a way to open the faucet so that I can replace the valve cartridge. I don't see a small opening anywhere and I can't seem to remove any top or tip of the faucet. I tried to unscrew the handle, but I am stuck afterwards. Any help would be much appreciated.
unscrew the nut under the sink and then you can turn the lever counter clockwise, sometimes there is plumbers putty that makes it hard to unscrew the lever without taking the nut under the sink off, watch this link
