How to Fix Dripping Faucets: Complete DIY Guide
A dripping faucet is not only annoying but can waste hundreds of gallons of water per year. This comprehensive guide will walk you through fixing most common faucet drips yourself.
Tools You'll Need:
- Adjustable wrench
- Screwdriver (Phillips and flathead)
- Replacement washers and O-rings
- Penetrating oil (like WD-40)
- Plumber's tape
- Clean rags
Step 1: Turn Off the Water Supply
Before starting any plumbing work, turn off the water supply. Look for shut-off valves under the sink. If there are none, you'll need to turn off the main water supply to your house.
Step 2: Plug the Drain
Place a plug or rag in the drain to prevent small parts from falling down the pipe.
Step 3: Remove the Faucet Handle
Most faucet handles have a decorative cap that hides the screw. Gently pry it off with a flathead screwdriver, then unscrew the handle.
Step 4: Remove the Packing Nut
Use an adjustable wrench to loosen and remove the packing nut. This will expose the valve stem.
Step 5: Replace Washers and O-Rings
Inspect the washers and O-rings for wear. Replace any that look damaged or worn. This is usually the cause of the drip.
Step 6: Reassemble the Faucet
Reassemble the faucet in reverse order. Apply plumber's tape to threaded connections for a better seal.
Step 7: Test Your Work
Turn the water supply back on slowly and test the faucet. Check for any leaks around the handle or base.
Common Mistakes to Avoid
- Forgetting to turn off the water supply
- Over-tightening connections (can cause cracks)
- Using the wrong size washers
- Not applying plumber's tape to threaded connections
When to Call a Professional
If you encounter any of these situations, it's best to call a licensed plumber:
- The faucet is very old and parts are no longer available
- You discover corroded pipes or major damage
- The leak continues after replacing all washers
- You're dealing with a complex faucet type (like a ball or cartridge faucet)
