Why is my kitchen faucet dripping?
A dripping faucet usually means a worn internal part. The most common culprit is a degraded rubber O-ring or a worn cartridge. Mineral deposits from hard water can also damage seals. A loose packing nut or a damaged valve seat can cause drips too. Each cause requires a slightly different fix.
How to fix a dripping kitchen faucet step by step
Start by turning off the hot and cold water valves under the sink. Open the faucet to release remaining water and pressure. Use a screwdriver to remove the handle screw and pull off the handle. Unscrew the retaining nut to expose the cartridge or stem. Pull out the old cartridge or stem with pliers. Install a matching replacement cartridge or stem. Replace any worn O-rings and apply plumber's grease. Reassemble the faucet and turn the water back on. Test for drips.
How to prevent a kitchen faucet from dripping
Regular maintenance extends faucet life. Clean the aerator monthly to remove debris. Avoid using excessive force when turning the handle. Address hard water with a water softener or descaling solution. Replace O-rings and cartridges every few years as preventive care. Fix minor leaks promptly to prevent worse damage.
When should you replace the faucet instead of fixing it?
If the faucet body is corroded or cracked, replacement is safer. Repeated leaks after repairs suggest a failing faucet. Older faucets with discontinued parts may be hard to fix. Compare repair costs with a new faucet price. If you lack the tools or confidence, call a licensed plumber. Some leaks indicate a deeper issue like high water pressure.
Common questions
How much water does a dripping faucet waste?
A faucet dripping once per second can waste over 3,000 gallons per year. That is enough for 180 showers. Fixing it saves water and money.
Can I fix a dripping faucet myself?
Yes, many drips are DIY-friendly. You need basic tools like a screwdriver and pliers. Replacement parts cost less than a plumber visit. Follow the steps carefully and shut off water first.
What tools do I need to fix a dripping faucet?
You typically need an adjustable wrench, screwdriver, and pliers. A basin wrench helps reach tight nuts. Plumber's tape and grease are useful. A replacement cartridge or O-ring kit is essential.
How do I know which cartridge my faucet needs?
Check the faucet brand and model on the underside or box. Remove the old cartridge and look for a number. Search online using that number or brand. Many manufacturers list parts in manuals.
Why does my faucet drip after replacing the cartridge?
The new cartridge might be the wrong size or not seated properly. Check for debris in the valve body. Ensure the O-rings are lubricated and aligned. If the drip persists, inspect the valve seat for damage.
Is a dripping faucet an emergency?
No, it is not an emergency, but it wastes water. A slow drip can cause mineral stains and higher bills. Address it within a week to avoid bigger issues.
Can hard water cause a faucet to drip?
Yes, hard water leaves mineral deposits that wear seals. These deposits can scratch the valve seat. Installing a water softener reduces this risk. Regular cleaning also helps.
When should I call a plumber for a dripping faucet?
Call a plumber if you cannot stop the drip after replacing parts. Also call if you see water pooling under the sink. If the faucet is old or complex, professional help is wise.
