Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.Once you have the handle off you just back off the cartridge by putting a wrench on the hex nut at the base of the stem. If the whole valve unit turns they you'll need someone under the sink to hold the valve body so it doesn't turn. You don't want to remove the nut under the sink. That will only make it more difficult. If anything you want to tighten that nut. If the cartridge is still seized up then you can soak it with something like PB Blaster, or CLR even white vinegar. Then come back to it an hour later.

Pam won't do anything. You can try one of the options I mentioned. Which nut is too big?
