Can I fix a dripping kitchen faucet myself? Yes, you can absolutely fix a dripping kitchen faucet yourself! Most common leaks come from simple, replaceable parts inside the handle or spout, making this a very manageable DIY faucet repair. Fixing a leaky faucet saves water, lowers your bill, and stops that annoying sound fast.

Why Faucets Drip: Pinpointing the Cause
A persistent drip, or a water dripping from spout, usually means one thing: a seal has failed inside your faucet. Over time, water pressure and mineral deposits wear down the internal parts. Knowing your faucet type is the first step to a quick fix. There are four main types of kitchen faucets, and each needs a different approach for plumbing repairs for kitchen.
Deciphering Faucet Types
Your faucet likely falls into one of these categories:
- Compression Faucets: These are older styles. They have two separate handles (hot and cold) that you must tighten down to stop the water flow. They rely on rubber or fiber washers.
- Ball Faucets: Common in kitchens, these use a single handle that moves over a rounded cap or ball joint to control flow and temperature. They have many small parts.
- Cartridge Faucets: These can have one or two handles. They use a hollow metal or plastic cartridge to control water flow. They offer smooth operation.
- Ceramic Disc Faucets: These are the most modern and durable. They use two ceramic discs that slide against each other to stop water flow completely. They rarely drip but are trickier to repair leaky faucet parts on.
Quick Steps to Stop the Leak Immediately
Before you start any major DIY faucet repair, you need to stop the water supply. This is crucial for safety and preventing messes.
Turn Off the Water Supply
- Look under your sink. You should see two shut-off valves, one for hot and one for cold water.
- Turn both valves clockwise until they stop. This closes the line to the faucet.
- If you cannot find or turn these valves, you must shut off the main water supply to your house. This is usually located near the water meter or where the line enters your home.
Drain Remaining Water
- Turn the faucet handles to the “on” position.
- Let any leftover water drain out completely. This relieves pressure in the lines.
- Close the sink drain plug. You don’t want small screws or parts falling down the pipe!
Fixing the Most Common Drip: The Compression Faucet
If you have an older faucet with separate hot and cold handles, you likely need a faucet washer replacement. These washers flatten out or crack, letting water seep past.
Tools You Will Need
- Screwdriver (flathead and Phillips)
- Adjustable wrench or basin wrench
- Pliers (needle-nose are helpful)
- Replacement washers (get a variety pack if unsure of size)
- Penetrating oil (if parts are stuck)
- Teflon tape
Step-by-Step Washer Replacement
Removing the Handle
- Pry off the decorative cap on top of the handle (it often says “H” or “C”). A small flathead screwdriver works well here.
- Use the screwdriver to tighten loose faucet parts by removing the screw found underneath the cap. Keep this screw safe!
- Lift the handle straight up and off the stem. If it’s stuck, gently wiggle it. Do not force it too hard.
Accessing the Stem and Washer
- You will see the packing nut or bonnet nut holding the stem in place. Use your adjustable wrench to loosen this nut (turn counter-clockwise).
- Once the nut is off, carefully pull the entire valve stem assembly out of the faucet body.
- Look at the bottom of the stem. You will see the rubber washer held in place by a brass screw.
- Remove the screw and take off the old, likely damaged, washer.
Installing the New Washer
- Match the old washer size to a new one from your replacement kit. Ensure the new washer is the correct shape (flat or beveled).
- Place the new washer onto the stem base.
- Secure it tightly with the brass screw. Do not overtighten, as this can damage the new rubber.
- This is also a good time to check the faucet valve replacement area or the packing material around the stem threads. If water leaks from around the handle when the water is on, you may need to wrap new Teflon tape around the threads or replace the packing washer.
Reassembling the Faucet
- Insert the stem assembly back into the faucet body.
- Hand-tighten the bonnet nut, then use the wrench for a final, snug turn. It must be tight enough to seal but loose enough not to damage the threads.
- Reattach the handle and the decorative cap.
Addressing Cartridge Faucets: The Heart of the Flow Control
If you have a single-handle faucet that drips, you most likely need to replace faucet cartridge. Cartridges are self-contained units that manage water mixing and flow.
Tools for Cartridge Repair
- Allen wrench set (often needed for single-handle sets)
- Pliers
- New replacement cartridge (Crucial: Buy the exact match for your faucet brand/model!)
- White vinegar (for cleaning mineral deposits)
How to Replace the Cartridge
Getting to the Cartridge
- Locate the small set screw holding the handle onto the faucet body. This screw is usually hidden beneath a decorative button or on the side/back of the handle base. Use the appropriate size Allen wrench to loosen it.
- Remove the handle completely.
- You might see a dome cap or retaining clip holding the cartridge in place. Remove this clip using needle-nose pliers or a small flathead screwdriver. Pay close attention to the orientation of this clip!
Removing and Replacing the Old Cartridge
- The cartridge often has small tabs or splines that fit into notches in the faucet body. Use pliers to gently grip the top of the cartridge body.
- Pull the old cartridge straight up. It might require some wiggling. Tip: If you have trouble removing it, some brands sell special cartridge puller tools.
- Inspect the empty housing for mineral buildup. Clean it carefully with a soft cloth dipped in vinegar.
- Insert the new cartridge, making absolutely sure it aligns perfectly with the notches or slots in the faucet body. If it’s not aligned correctly, the handle won’t move right, or the faucet will still leak.
- Replace the retaining clip or cap that holds the cartridge down.
Final Assembly and Testing
- Reattach the handle and tighten the set screw.
- Slowly turn the water supply back on underneath the sink.
- Test the faucet. If the drip is gone, you successfully performed a faucet valve replacement on the cartridge!
Troubleshooting Ball Faucets (Single Handle Complexity)
Ball faucets are known for having many parts, making them a bit more complex for basic plumbing repairs for kitchen novices. They often drip from the spout or leak around the base of the handle.
Key Components of a Ball Faucet
- Cam and Packing
- Inlet Seals and Springs
- The Ball itself
Repairing a Ball Faucet Leak
- Follow the handle removal steps similar to the cartridge faucet (look for a set screw).
- Once the handle is off, remove the cap or collar nut. This often requires a special tool supplied with repair kits, but sometimes large slip-joint pliers work if wrapped in a cloth to prevent scratching.
- Lift out the cam assembly (this often looks like a slotted plastic piece).
- Remove the rotating ball. Note its orientation—it only fits one way.
- Look deep into the faucet body housing. You will see small rubber seats and springs resting in small openings. These are the main culprits for leaks in this style.
- Use needle-nose pliers to remove the old springs and seats.
- Install new springs (the narrow end goes down first) and place the new rubber seats on top of them.
- Reinsert the ball, making sure the small key slot on the ball lines up with the corresponding notch in the faucet body.
- Replace the cam assembly and tighten the cap firmly.
If you fix squeaky faucet issues while you are here, it is often because the cam packing needs lubrication or replacement. Apply a tiny bit of plumber’s grease to the cam and packing assembly before reinstalling.
Dealing with Leaks Around the Handle Base
If water is seeping out from under the handle rather than from the spout, the issue is usually a worn-out seal or packing nut tightness, not the main valve itself.
Fixing Handle Base Leaks
- Compression Faucets: Tighten the packing nut slightly. If that fails, you need to replace faucet cartridge components or the packing material inside the bonnet, often using new Teflon tape on the threads before reassembling.
- Single-Handle Faucets: This usually means the O-rings at the base of the cartridge, or the gasket seal under the decorative cap, are worn out. You must disassemble the faucet down to the cartridge level and replace these small rubber rings.
The Ceramic Disc Faucet: A Different Approach
Ceramic disc faucets are highly reliable. When they drip, it usually means the ceramic discs themselves are cracked (rare) or the inlet/outlet seals beneath the disc cartridge have failed.
Repairing Ceramic Disc Faucets
- Disassembly follows the single-handle process: remove the handle and the protective cap or dome.
- You will see a cylinder, which is the disc cartridge. Remove the screws or retaining nuts holding it in place.
- Lift out the cartridge.
- Flip the cartridge over. You should see inlet and outlet seals beneath it. Carefully pry these out.
- Clean the area thoroughly. Install new seals.
- If the seals don’t solve the issue, the entire cartridge assembly needs replacement. Since these parts are highly specialized, ensure you get an exact match. This is less of a washer swap and more of a component swap.
Essential Maintenance Tips to Prevent Future Leaks
Prevention is far easier than reactive plumbing repairs for kitchen work! Good habits keep your faucet running smoothly for years.
Water Quality Management
Hard water (water high in minerals like calcium) is the enemy of faucet internals. Minerals build up inside the narrow passageways, causing seals to stick or wear unevenly.
- Install a water softener if your area has very hard water.
- Periodically flush your faucet by removing the aerator (the screen at the tip of the spout) and running the water full blast for a minute.
Handling the Handles Correctly
How you operate the faucet directly affects its lifespan.
- Avoid slamming handles shut, especially on compression faucets. This rapid stopping action stresses washers and seats.
- When you need to stop running faucet flow, turn handles smoothly and gently.
Regular Inspection
Make it a habit to check your faucet every few months. If you hear a slight drip or notice the handle becoming stiff, address it right away. A small issue today prevents a major leak tomorrow. If you need to tighten loose faucet components, do so gently.
Table of Common Faucet Issues and Solutions
| Symptom | Likely Cause | Required Repair Action | LSI Keywords Targeted |
|---|---|---|---|
| Drip from Spout (Two Handles) | Worn Washer | Faucet washer replacement | DIY faucet repair |
| Drip from Spout (Single Handle) | Worn Cartridge or Seals | Replace faucet cartridge | Repair leaky faucet |
| Leak around Handle Base | Worn O-rings or Loose Nut | Tighten nut or replace O-rings | Plumbing repairs for kitchen |
| Faucet is Hard to Turn/Squeaks | Lack of lubrication or Worn Packing | Lubricate or perform faucet valve replacement | Fix squeaky faucet |
| Water Leaks from Spout After Closing | Failed Main Valve Component | Full faucet valve replacement | Stop running faucet |
Finalizing Your DIY Project
Once you have turned the water back on, check your work carefully.
- Turn the water on slowly beneath the sink.
- Listen and watch for any immediate leaks, especially around the base of the handles.
- Operate the faucet through its full range (hot, cold, mix).
- If the drip is gone, congratulations! You have successfully handled your DIY faucet repair. If you still have a leak, you may have missed a small component, or the main valve body itself might be damaged, requiring a professional plumber or a full faucet valve replacement of the entire unit.
If you stop running faucet water successfully but then find a persistent, slow drip after assembly, take everything apart again. Often, debris gets trapped between the new seal and the metal seat, preventing a perfect seal. Clean and reassemble carefully.
Frequently Asked Questions (FAQ)
Q: How long should a faucet repair take?
A: For an experienced person, fixing a simple washer or cartridge usually takes 30 minutes to an hour. If it’s your first time, plan for about 1.5 to 2 hours, especially if you have trouble locating or removing stuck parts. The longest part is often driving to the store to get the exact right part!
Q: Can I use Teflon tape on compression faucets?
A: Yes, Teflon tape (or pipe dope) is excellent for sealing the threads where the bonnet nut meets the faucet body. This helps stop running faucet water that escapes around the stem assembly, rather than from the spout. It does not affect the washer sealing function itself.
Q: Why does my faucet fix squeaky faucet problem return quickly?
A: If squeaking or stiffness comes back fast after lubrication, it usually means the packing material or O-rings are severely deteriorated, or the faucet handle itself is rubbing against the faucet body due to corrosion. In this case, a full faucet valve replacement of the internal cartridge or stem assembly is necessary, not just lubrication.
Q: What if I cannot find the exact replacement cartridge?
A: This is common with older or less-known faucet brands. Take the old cartridge, any retaining clips, and perhaps a photo of the faucet body to a specialized plumbing supply store, not just a big-box retailer. Sometimes, you can find universal repair kits, but matching the specific brand (Moen, Delta, Kohler, etc.) is always best for a lasting repair leaky faucet solution.
Q: Does cleaning mineral deposits help stop running faucet issues?
A: Absolutely. Mineral deposits create uneven surfaces that prevent washers and discs from sealing flatly. Thoroughly cleaning the valve seat, especially when performing a faucet washer replacement, ensures the new seal makes perfect contact, which is key to eliminating the drip.
