Common Causes of a Leaky Kitchen Faucet
Kitchen faucet leaks usually come from a worn cartridge, damaged O-rings, a faulty washer, or a loose connection. Identifying your faucet type, cartridge, ball, ceramic disc, or compression, helps you choose the right repair.
Tools You'll Need
- Adjustable wrench and screwdrivers
- Allen keys
- Replacement cartridge, O-rings, or washers
- Plumber's grease and a clean rag
Step 1: Turn Off the Water
Close the shutoff valves under the sink and open the faucet to release pressure. Plug the drain so small parts don't fall in.
Step 2: Disassemble the Faucet
Remove the handle by unscrewing the set screw or decorative cap. Take photos as you go so reassembly is straightforward.
Step 3: Replace the Worn Parts
Pull out the cartridge or stem and inspect the O-rings and washers. Replace any damaged components with exact-match parts from your hardware store.
Step 4: Reassemble and Test
Apply plumber's grease to the new parts, reassemble the faucet, and turn the water back on slowly. Run the faucet and check that the leak is gone.
When to Call a Plumber
If the faucet still leaks after replacing the internal parts, or if you find corrosion in the valve body, a professional plumber can help prevent further damage.
