If you need to know how to stop a kitchen faucet from dripping, begin by identifying where the water appears. A drip from the end of the spout, a leak around the handle, and moisture under the sink can have different causes. The correct repair depends on the faucet’s actual internal design, so avoid ordering parts or forcing components before identifying the fixture.
Why Is Your Kitchen Faucet Dripping?
A faucet can drip when an internal sealing component no longer closes properly. Depending on the design, the cause may involve a worn cartridge, valve seat, washer, O-ring, seal, or another product-specific part. Mineral buildup or debris can also interfere with proper sealing.
| Where you see water | Possible area to inspect | Important note |
|---|---|---|
| End of the spout | Cartridge, valve, seat, or internal seal | The exact repair depends on faucet type |
| Around a handle | Handle assembly, cartridge seal, or O-ring | Avoid overtightening or forcing decorative components |
| Base of the spout | Spout seal or O-ring | Confirm whether the spout is designed to be removed |
| Under the sink | Supply connection, mounting area, or hose | Shut off water promptly and inspect carefully |
How to Stop a Kitchen Faucet from Dripping
1. Find the Exact Leak Location
Dry the faucet and surrounding countertop, then observe where fresh water appears. Check both hot and cold handle operation if the fixture has separate controls. A paper towel can help identify moisture without scratching the finish.
2. Shut Off the Water Supply
Close the appropriate hot and cold shutoff valves beneath the sink. Open the faucet to release remaining pressure. If the shutoff valves do not work or you cannot identify the supply, stop and contact a qualified plumber.
3. Identify the Faucet and Repair Parts
Find the product documentation or manufacturer information. A bridge faucet, single-handle faucet, and compression-style design do not necessarily use interchangeable cartridges or seals. Take clear photos before disassembly.
4. Protect the Sink and Faucet Finish
Cover the drain and place a towel in the basin. Use the correct tools, and protect visible brass with a soft cloth where appropriate. Do not grip unlacquered brass directly with serrated pliers.
5. Inspect and Replace the Correct Component
Following the specific product instructions, remove the handle or access cover and inspect the relevant cartridge, valve, washer, or O-ring. Replace only with a verified compatible part. Clean loose debris gently and avoid scratching sealing surfaces.
Manufacturer Delta explains why the correct repair depends on the faucet’s internal assembly in its guide to repairing a leaking faucet.
6. Reassemble and Test Slowly
Reinstall parts in their original order, restore the water gradually, and check the spout, handles, base, and supply connections. If the drip continues, stop rather than repeatedly overtightening the assembly.
Special Considerations for Brass and Bridge Faucets
A bridge faucet has separate controls and exposed metalwork, so it is especially important to identify which side or component is leaking. Unlacquered brass can develop natural patina, but a changing finish should never be confused with an active plumbing leak.

Repair or Replace the Faucet?
Repair can make sense when the fixture is otherwise sound and compatible parts are available. Replacement may be more practical if the body is damaged, the same leak keeps returning, parts cannot be identified, or the faucet no longer suits the sink. Our kitchen faucet replacement guide explains the broader installation process.
Frequently Asked Questions
Why does my faucet drip after I turn it off?
An internal valve, cartridge, washer, or seal may not be closing fully. The exact cause depends on the faucet design.
Can I fix a dripping faucet without turning off the water?
Do not disassemble a faucet without first isolating the relevant water supply and relieving pressure.
Will tightening the handle stop the drip?
Not necessarily. Overtightening can damage components, and many leaks require a correctly matched replacement part.
Does a dripping faucet always need replacing?
No. A compatible cartridge, washer, seal, or O-ring may solve the problem when the rest of the fixture is in good condition.
When should I call a plumber?
Call a professional if shutoff valves fail, water leaks under the sink, the fixture cannot be identified, a component is seized, or the repair continues to leak.
To understand how to stop a kitchen faucet from dripping, focus on accurate diagnosis, safe water isolation, and the correct product-specific repair—not guesswork or excessive force.
