How to Repair a Leaky Faucet Base (Single Handle) · Step 3 of 6
In this video
With the handle and decorative cover removed, you will see a large brass retaining nut holding the cartridge in place. Use an adjustable wrench to grip the nut and turn it counter-clockwise to loosen and remove it. After the nut is removed, firmly grasp the plastic stem of the old cartridge and pull it straight up and out of the faucet body.
Goal: Remove the faulty cartridge
- If the retaining nut is stuck due to mineral buildup, you can spray it with a penetrating oil and let it sit for a few minutes before trying again.

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.
