The short answer
Common Causes
A dripping faucet often traces to a single worn part. The rubber washer inside the handle can flatten over time, letting water slip past. A loose or damaged O-ring around the stem can cause drips near the spout. Corroded valve seats, where the washer presses down, also break the seal.
Mineral deposits from hard water can build up inside the faucet. These rough spots stop the washer from seating fully. In some cases, the cartridge in a single-handle faucet wears out. Identifying the exact cause usually requires taking the faucet apart and inspecting the internal parts.
- Worn rubber washer
- Loose or cracked O-ring
- Corroded valve seat
- Mineral buildup inside
- Faulty cartridge in single-handle models
How to Inspect
Start by turning off the water supply under the sink. Remove the handle and the packing nut to expose the stem. Look for visible wear on the washer and O-ring. Feel for rough spots on the valve seat. If you see mineral crust, that often explains the drip.
Check the spout for leaks when the faucet is off. A drip from the spout usually means a washer or cartridge issue. A leak around the handle base points to a loose O-ring. If you are unsure, a plumber can take the faucet apart and find the worn part.
Simple Fixes
Many drips stop with a new washer or O-ring. Turn off the water, remove the handle, and replace the damaged part. Clean any mineral buildup with vinegar or a mild descaler. Reassemble the faucet and test it. This often solves the problem without replacing the whole fixture.
For a single-handle faucet, you may need to replace the cartridge. Cartridges vary by brand, so take the old one to a hardware store for a match. If the faucet body is cracked or badly corroded, replacement may be the better route. A plumber can handle that job.
When to Call Pros
If the drip continues after replacing parts, the faucet may have internal damage. A plumber can assess the fixture and recommend a repair or replacement. If water has leaked into the cabinet or flooring, you might need water damage help. Acting quickly prevents wood rot and mold.
Leaks that spread beyond the sink area can soak drywall or subflooring. Local water damage pros can dry out the area and check for hidden moisture. They can also map the extent of the damage. That helps you decide what repairs are needed.
- Drip persists after new parts
- Water stains on cabinet or floor
- Soft or warped wood near sink
- Musty smell under the sink
- Leak travels to ceiling below
Prevent Future Drips
Regular maintenance can extend a faucet's life. Check washers and O-rings every couple of years for wear. Clean aerators to remove mineral buildup. Avoid overtightening handles, which can crush washers. In areas with hard water, periodic descaling helps keep parts smooth.
