Remove and replace the cartridge. Gently pry out the old cartridge with a small flathead screwdriver. Clean any debris from behind the valve and clean the inlet lines to prevent damage to O-rings. Apply plumber's grease to the O-rings on the new cartridge. Carefully insert the new cartridge into the valve body, ensuring proper alignment and install it, keeping hot to the left and cold to the right. Ensure cartridge sits flush.

Goal: Stop the leak

  • Apply plumber's grease to O-rings to ease installation and prevent future binding.

FAQs

What essential tools do I truly need for this faucet repair, beyond the specialized items listed?

You'll primarily need screwdrivers (flathead and Phillips), an adjustable wrench, and possibly slip-joint or tongue-and-groove pliers for stubborn nuts. A bucket and old towels are essential for catching water. The specific brands mentioned are examples, not strict requirements.

How long should a beginner expect this project to take, and what's the average cost for parts?

For a beginner, this project typically takes 1-2 hours, including water shut-off and cleanup. The main cost is the replacement cartridge, which usually ranges from $10-$30 depending on your faucet's brand and model. It's a cost-effective alternative to calling a plumber.

What's the most common reason a two-handle faucet drips, and how can I ensure I buy the correct replacement cartridge?

A worn-out internal cartridge or O-rings are almost always the cause of a dripping faucet. To get the right replacement, identify your faucet's brand and model (often stamped on the faucet body) and take the old cartridge with you to the store for a direct comparison.

What crucial safety precautions should I take before attempting to fix my dripping faucet?

Always shut off the hot and cold water supply valves under the sink before starting to prevent leaks and potential flooding. Place a bucket under the faucet and have plenty of old towels on hand to manage any residual water in the lines.
