A dripping kitchen or bathroom faucet may seem like a minor annoyance, but it usually means an internal part is no longer sealing correctly. Worn cartridges, washers, O-rings, seals, mineral buildup or aging faucet components can all cause water to continue dripping after the handle is turned off.
Some minor faucet problems can be handled with a straightforward DIY repair. However, persistent leaks, corrosion or damaged plumbing connections may require professional faucet repair and installation.
In this guide, we'll explain how to fix a leaky faucet, what commonly causes faucet leaks, which components you should inspect and when faucet replacement may be a better choice than another repair.

Quick Answer: How Do You Fix a Leaky Faucet?
To fix a basic leaky faucet:
- Shut off the hot and cold water supply.
- Close or cover the sink drain.
- Identify where the faucet is leaking.
- Remove the faucet handle carefully.
- Inspect the cartridge, washer, O-ring and seals.
- Replace any damaged components.
- Reassemble the faucet.
- Slowly restore the water.
- Check the faucet and plumbing connections for leaks.
The exact repair depends on the type of faucet you have.
If replacing a worn component does not stop the leak, there may be corrosion, valve damage or another plumbing problem that requires professional inspection.
Why Is My Faucet Leaking?
Before taking the faucet apart, pay attention to where the water appears.
The location of the leak can provide useful clues about what may be wrong.
Faucet Dripping From the Spout
If water continues dripping from the spout after the handle is completely closed, an internal component may no longer be creating a watertight seal.
Common causes include:
- Worn washer
- Damaged cartridge
- Worn seals
- Mineral buildup
- Valve damage
- Internal corrosion
Persistent dripping is often one of the first signs that a faucet needs repair
Water Leaking Around the Faucet Handle
Water collecting around the handle may indicate a worn:
- O-ring
- Cartridge
- Seal
- Packing component
The faucet may still operate normally while water escapes around the handle.
Ignoring the problem can allow moisture to spread onto the sink or countertop.
Water Leaking Around the Faucet Base
If water is appearing around the base of your kitchen or bathroom faucet, the problem may involve:
- Worn base seals
- Loose mounting hardware
- Damaged O-rings
- Water leaking from another section of the fixture
Leaks around the base should be addressed before water begins reaching the cabinet or materials underneath the sink.
Water Leaking Under the Sink
Not every leak underneath a sink comes directly from the faucet.
Check around:
- Hot water supply line
- Cold water supply line
- Shutoff valves
- Faucet connections
- Drain connections
- Faucet mounting area
If the source is difficult to identify, professional leak detection and repair services can help determine exactly where the water is coming from.

How to Fix a Leaky Faucet Step by Step
Different faucet designs use different internal components, but the basic troubleshooting process is similar.
Step 1: Turn Off the Water Supply
Look underneath the sink for the hot and cold water shutoff valves.
Turn both valves clockwise until they are fully closed.
Then open the faucet briefly to release any remaining water pressure.
Before taking anything apart, confirm that water is no longer flowing.
What If the Shutoff Valve Doesn't Work?
If a shutoff valve does not stop the water, avoid continuing with the repair.
An old or damaged shutoff valve may need replacement before the faucet can be safely serviced.
Step 2: Protect the Sink Drain
Small screws and faucet parts can easily fall into the drain.
Close the sink stopper or place a towel over the drain opening before removing any parts.
It is also helpful to keep components organized in the order they are removed.
Step 3: Identify Your Faucet Type
Knowing your faucet type will make it easier to identify the part that may be causing the leak.
Compression Faucet
Compression faucets usually have separate hot and cold handles.
They commonly use rubber washers that press against valve seats to stop water flow.
A worn washer can cause repeated dripping.
Cartridge Faucet
Cartridge faucets contain an internal cartridge that controls water flow.
Signs of a worn cartridge may include:
- Dripping faucet
- Leaking handle
- Difficult handle movement
- Poor temperature control
If your cartridge is damaged or difficult to remove, Dream Home Plumbing also provides professional faucet cartridge replacement.
Ball Faucet
Ball-style faucets use several internal seals and components.
Because they contain several potential leak points, troubleshooting them can sometimes be more complicated.
Ceramic Disc Faucet
Ceramic disc faucets are generally durable but can still develop worn seals or cartridge-related problems over time.
Step 4: Remove the Faucet Handle
Depending on the fixture, the handle may be held in place by:
- Visible screw
- Hidden screw under a decorative cap
- Set screw
- Manufacturer-specific fastener
Remove the handle carefully.
Do not force stuck faucet components.
Older fixtures can develop mineral deposits and corrosion that make parts difficult to remove.
Too much pressure may damage the faucet or nearby plumbing.
Step 5: Inspect the Internal Faucet Components
Once the faucet is open, inspect the internal components closely.
Look for:
- Cracked washers
- Flattened seals
- Worn O-rings
- Damaged cartridges
- Mineral deposits
- Corrosion
- Broken plastic parts
- Loose components
If you find a damaged component, replacing it with a compatible part may solve the problem.
Whenever possible, use replacement parts designed for the faucet manufacturer and model.
Step 6: Replace the Damaged Part
Depending on the faucet, you may need to replace:
- Washer
- O-ring
- Cartridge
- Seal
- Valve component
For many modern faucets, replacing the complete cartridge can be more reliable than trying to repair small internal cartridge components.
Step 7: Reassemble the Faucet
Reinstall the faucet components in reverse order.
Make sure everything is positioned correctly before tightening.
Avoid overtightening fasteners.
Too much force can damage seals or make the fixture harder to repair later.
Step 8: Restore the Water Supply
Slowly reopen the hot and cold shutoff valves.
Then operate the faucet several times.
Check carefully for water around:
- Spout
- Handle
- Faucet base
- Supply lines
- Shutoff valves
- Cabinet underneath the sink
If everything remains dry and the dripping has stopped, the repair was likely successful.

What If Your Faucet Still Leaks After Repair?
Replacing one damaged washer or cartridge does not always solve the problem.
A faucet may continue leaking because of:
- Damaged valve seat
- Wrong replacement cartridge
- Internal corrosion
- Mineral buildup
- Multiple worn components
- Damaged faucet body
- Loose plumbing connections
- Failing shutoff valve
Repeatedly replacing parts on an old or deteriorated fixture may eventually cost more than replacing the faucet.
This is where a professional plumber can help determine whether another repair makes sense or whether faucet replacement would provide a better long-term solution.
Should You Repair or Replace a Leaky Faucet?
Not every dripping faucet needs to be replaced.
Repair may be the best option when:
- The faucet is relatively new
- Only one internal component has failed
- Replacement parts are readily available
- The faucet is in otherwise good condition
- The leak has not returned repeatedly
Replacement may be the better option when:
- The faucet is badly corroded
- Parts are difficult to find
- The fixture has multiple leaks
- Repairs have already been attempted
- The faucet body is damaged
- Handles are difficult to operate
- You want to upgrade the kitchen or bathroom
A licensed plumber can inspect the fixture and help you choose the most practical option.
When Is Kitchen Faucet Replacement a Better Choice?
Kitchen faucets receive heavy daily use.
Over time, cartridges, pull-down hoses, seals, handles and internal components can wear out.
You may want to consider kitchen faucet replacement if your existing faucet has:
- Persistent dripping
- Corrosion
- Leaking pull-down hose
- Loose handle
- Low water flow
- Multiple previous repairs
- Water underneath the sink
- Outdated design
- Damaged faucet body
Replacing an aging fixture can also be a good opportunity to upgrade the look or functionality of your kitchen.

Why Hire a Plumber for Faucet Installation?
Installing a new faucet can look simple until the old fixture is removed.
That is when homeowners sometimes discover corroded supply lines, difficult mounting hardware, failing shutoff valves or incompatible connections.
Hiring a plumber for faucet installation can help make sure the fixture is installed and tested correctly.
Professional faucet installation may include:
- Removing the old faucet
- Inspecting existing plumbing connections
- Checking shutoff valves
- Installing the new fixture
- Connecting supply lines
- Securing the faucet properly
- Checking seals and connections
- Testing hot and cold water
- Inspecting underneath the sink for leaks
An expert plumber for faucet installation can also help determine whether your new faucet is compatible with the existing sink and plumbing setup.

More complicated leaks, corroded fixtures and difficult cartridge repairs may require professional service.
