A dripping kitchen faucet can waste water, raise utility bills, and create irritating noise. Understanding the causes and following a systematic repair process can help homeowners and maintenance teams fix the issue efficiently. Whether the faucet is a single-handle, double-handle, or pull-out type, the solution usually involves replacing worn-out internal components and performing simple checks.
Before repairing, determine the faucet type, as the internal mechanism differs among designs. The most common are:
| Faucet Type | Mechanism | Typical Cause of Dripping |
|---|---|---|
| Compression | Rubber washer seals water flow | Worn washer or seat |
| Cartridge | Cartridge with seals and springs | Damaged cartridge or O-ring |
| Ball | Ball bearing and control springs | Corroded seals or springs |
| Ceramic Disk | Two ceramic disks control flow | Mineral buildup or worn seals |
Recognizing the type helps you select the right replacement parts and tools, preventing unnecessary disassembly.
A leak typically originates from the spout or handle. The main reasons include:
Worn-Out Washer
The washer pressed against the valve seat deteriorates with time. Once worn, water leaks through even when the handle is turned off. Replacing it usually stops the drip.
Damaged O-Ring
Found on the stem screw, an O-ring creates a watertight seal. If it cracks or loosens, water may leak near the handle. A new O-ring ensures proper sealing.
Corroded Valve Seat
Hard water minerals corrode the metal valve seat that connects the faucet and spout. This can cause persistent leaking around the base. Cleaning or replacing the valve seat restores smooth operation.
Loose or Faulty Cartridge
Cartridge-style faucets rely on rubber seals to control flow. When seals become brittle or the cartridge wears down, water seeps through even when closed.
Water Pressure Issues
Extremely high water pressure can cause intermittent drips, particularly at night. Installing a pressure regulator helps maintain stable water flow.
Repairing a dripping faucet does not require advanced plumbing skills but does demand careful steps:
Turn Off the Water Supply
Locate and close the shut-off valves under the sink. Open the faucet to release any remaining water.
Plug the Drain
Use a sink plug or cloth to prevent small parts from falling down the drain during repair.
Remove the Handle
Pry off the decorative cap, unscrew the handle, and gently pull it off to access the internal parts.
Inspect and Replace Internal Parts
For compression faucets, replace washers and O-rings.
For cartridge faucets, remove and replace the cartridge.
For ball-type, inspect the ball, springs, and seals.
For ceramic disk faucets, clean or replace the disk assembly.
Reassemble and Test
Reinstall components in reverse order. Turn the water back on and test for any remaining leaks. If dripping persists, inspect for corrosion or incorrect part alignment.
To minimize future dripping and extend faucet lifespan:
Regularly clean the aerator to prevent mineral buildup.
Avoid over-tightening handles when turning off water.
Replace washers or seals every few years as part of preventive maintenance.
Install a water softener if your area has hard water to reduce corrosion.
Keep spare cartridges and O-rings from the same manufacturer for quicker fixes.
If leaks continue after part replacement, it may indicate deeper wear in the valve body or corrosion that cleaning cannot resolve. In such cases, a complete replacement is cost-effective and ensures long-term reliability. Modern kitchen faucets from professional manufacturers are designed for both functionality and style, making them worthwhile upgrades.
