Why You Shouldn't Ignore a Dripping Faucet
A faucet that drips once per second wastes more than 3,000 gallons of water per year. Beyond the water bill, constant moisture can damage sink cabinets, promote mold growth, and wear out your plumbing faster. The good news: fixing a leaky faucet is one of the most approachable DIY plumbing repairs — and it usually takes less than an hour.
Tools & Materials You'll Need
- Adjustable wrench or basin wrench
- Phillips and flathead screwdrivers
- Replacement cartridge, washer, or O-ring (match to your faucet brand/model)
- Plumber's grease
- Plumber's tape (Teflon tape)
- Bucket or towel
Step 1: Identify Your Faucet Type
The repair method depends on your faucet type:
- Ball faucet — Single handle that rotates over a ball-shaped cap (common in kitchens)
- Cartridge faucet — Single or double handle with a cartridge inside
- Ceramic disc faucet — Single lever over a wide cylindrical body
- Compression faucet — Two separate handles, older style
Step 2: Shut Off the Water Supply
Turn off the shut-off valves under the sink (clockwise to close). Turn on the faucet to release any remaining pressure and drain residual water.
Step 3: Disassemble the Faucet Handle
- Remove the decorative cap on top of the handle to expose the screw
- Unscrew and lift off the handle
- Use a wrench to remove the packing nut, then pull out the stem or cartridge
Step 4: Replace the Worn Part
- Compression faucet: Replace the rubber washer at the bottom of the stem
- Cartridge faucet: Pull out the cartridge and replace with an identical one
- Ball faucet: Replace the springs, seats, and O-rings (use a repair kit)
- Ceramic disc: Clean or replace the ceramic disc cylinder
Apply plumber's grease to O-rings and rubber parts before reinstalling.
Step 5: Reassemble & Test
- Reassemble in reverse order
- Turn the water supply back on slowly
- Test the faucet — no more drip!
When to Call a Professional
If the leak persists after replacing parts, the faucet seat may be damaged and require resurfacing, or the faucet may need full replacement. Signs of corrosion or mineral buildup around the valve body are also worth a professional evaluation.
