Unscrew the faucet handle from the valve body by turning it counter-clockwise. Once the handle is removed, you will see the brass bonnet nut that secures the cartridge. Use slip-joint pliers or an adjustable wrench to loosen and unscrew this nut. A rag can be placed between the tool and the nut to prevent scratching the finish. Lift the nut off to expose the cartridge.
Goal: Access the faucet cartridge by removing the handle and securing nut.

FAQs
Do I really need all the specific tools listed, like the bent pick or screw-holding screwdrivers?
While specific tools like a bent pick (e.g., TEKTON 90-Degree Bent Pick) make removing O-rings much easier and prevent damage, a small flathead screwdriver or sturdy tweezers can sometimes work in a pinch. The screw-holding screwdriver is helpful for not dropping tiny screws into the sink, but any appropriately sized screwdriver will function. An adjustable wrench is essential for loosening nuts and is non-negotiable.
What's the absolute most critical safety precaution for this faucet repair?
The most critical step is always to **completely shut off the water supply** to the faucet before beginning any disassembly. This prevents accidental floods and potential water damage to your home. After shutting off the hot and cold water valves, open the faucet briefly to relieve any residual water pressure and drain remaining water from the lines.
How long should a beginner expect this repair to take, and what's the typical cost?
For a beginner, this project typically takes 1 to 2 hours, including the initial diagnosis, repair, and clean-up. The cost is usually very low, as you're primarily purchasing an O-ring kit (like the DANCO 200-Piece O-Ring Kit) or a faucet repair kit, which typically costs between $5 and $20. This makes it a very cost-effective DIY fix compared to hiring a professional plumber.
What if I replace the O-rings, but the faucet still leaks from the base?
If the leak persists after replacing the O-rings, first double-check that all new O-rings are correctly seated, not twisted, and adequately lubricated with plumber's grease. Sometimes, the issue isn't just the O-rings but a damaged faucet cartridge or housing, which may need replacement. Ensure all connections are tightened snugly, but avoid overtightening, which can crack components.
