Slowly turn the handle on the new shutoff valve counter-clockwise to restore the water supply. Check for any leaks at the connections. Then, go to the faucet and use a screwdriver or aerator key to unscrew the faucet's aerator. Turn on the faucet and let the water run for about a minute to flush out any debris from the lines. Turn the water off, reinstall the aerator, and turn the water on again to test for normal flow.

Goal: Restore water pressure and flush debris from the lines.

  • Flushing the line prevents debris from clogging the new aerator.

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.
