How do I fix a dripping faucet?
Identify the Faucet Type
Most dripping faucets are compression, ball, cartridge, or ceramic disc types. Compression faucets usually have rubber washers that wear out. Cartridge and ceramic disc faucets often need a new cartridge or disc.
Check under the sink or the faucet brand for a model number. That helps you buy the right replacement parts. If you can't find it, take a photo of the faucet to a hardware store for help.
Step-by-Step Repair
Shut off the water supply valves under the sink. Plug the drain so small parts don't fall in. Remove the handle by prying off the cap and unscrewing the screw underneath.
For a compression faucet, unscrew the packing nut and pull out the stem. Replace the washer at the bottom and the O-ring on the stem. For cartridge faucets, pull out the cartridge and take it to a store to match a new one.
Reassemble in reverse order, turn the water back on, and test. If it still drips, the valve seat may be damaged and need resurfacing or replacement.
- Turn off water supply and open the faucet to drain pressure
- Remove handle and expose the internal parts
- Replace worn washer, O-ring, or cartridge
- Clean or replace the valve seat if corroded
- Reassemble and test for leaks
Common mistakes
- Forgetting to turn off the water supply before disassembly.
- Using too much force and stripping screws or breaking plastic parts.
- Buying a generic washer that doesn't match the faucet model, causing a new leak.
