A dripping bathroom faucet isn’t just annoying—it can waste water and drive up your utility bill. The good news? Fixing it is often easier than you might think. With a few basic tools and some patience, you can tackle this DIY project in no time. Here’s a clear, step-by-step guide to help you stop that drip for good.
What You’ll Need
Before you start, gather these tools and supplies:
-
Adjustable wrench
-
Screwdriver (flat head or Phillips, depending on your faucet)
-
Replacement washer or cartridge (check your faucet type)
-
Plumber’s tape (also called Teflon tape)
-
Towel or rag
-
Bucket or bowl (to catch water)
-
Vinegar (optional, for cleaning)
Step 1: Turn Off the Water Supply
First things first—shut off the water to avoid a messy situation. Look under the sink for the shut-off valves. Turn them clockwise to close them. If there are no valves under the sink, you may need to turn off the main water supply for your home.
Once the water is off, turn the faucet on to release any remaining water in the pipes. This will prevent spills when you start disassembling the faucet.
Step 2: Identify Your Faucet Type
There are four common types of bathroom faucets:
-
Compression Faucets: These have separate hot and cold handles and use rubber washers.
-
Cartridge Faucets: These have one or two handles and use a cartridge instead of washers.
-
Ball Faucets: These have a single handle and a rounded cap.
-
Ceramic Disk Faucets: These have a single handle and are known for durability.
Knowing your faucet type will help you determine which parts need replacing. If you’re unsure, take a photo and ask for help at your local hardware store.
Step 3: Disassemble the Faucet
-
Remove the Handle: Use a screwdriver to remove the decorative cap on the handle (if there is one). Then, unscrew the handle and gently pull it off. If it’s stuck, try wiggling it or using a handle puller tool.
-
Expose the Inner Parts: Once the handle is off, you’ll see the stem or cartridge. Use your adjustable wrench to loosen and remove it.
Step 4: Inspect and Replace the Problem Part
-
For Compression Faucets: Check the rubber washer at the bottom of the stem. If it’s worn or damaged, replace it with a new one of the same size.
-
For Cartridge Faucets: Remove the cartridge and take it to the hardware store to find an exact match. Cartridges vary by brand, so it’s important to get the right one.
-
For Ball Faucets: Inspect the rubber seals and springs inside the faucet. Replace any worn parts.
-
For Ceramic Disk Faucets: These rarely need repairs, but if they do, you’ll likely need to replace the entire disk.
Step 5: Reassemble the Faucet
-
Apply Plumber’s Tape: Wrap plumber’s tape around the threads of the stem or cartridge before reinstalling it. This helps create a watertight seal.
-
Tighten the Parts: Reinstall the stem or cartridge and tighten it with your wrench. Be careful not to overtighten, as this can damage the faucet.
-
Reattach the Handle: Slide the handle back into place and secure it with the screw. Replace the decorative cap if there is one.
Step 6: Turn the Water Back On
Slowly turn the water supply valves counterclockwise to restore water flow. Check for leaks around the faucet and handles. If everything looks good, turn the faucet on and off a few times to test it.
Step 7: Clean Up
If you notice mineral buildup on the faucet, soak the parts in vinegar for a few hours to dissolve the deposits. Wipe everything down with a clean cloth before reassembling.
When to Call a Pro
If you’ve followed these steps and the faucet is still dripping, or if you encounter a problem you’re not comfortable fixing, it might be time to call a plumber. Some issues, like corroded pipes or complex internal damage, require professional expertise.
