Why Do Faucets Drip?

Faucets are designed with internal components that control water flow. When these components wear out, they can no longer create a watertight seal, leading to leaks. For two-handle faucets, each handle controls a separate water line – hot and cold. The dripping often originates from the internal valve mechanism for the handle that is leaking.

Common Culprits for Dripping Faucets:

Worn-out Washers: These are small, rubber or nylon discs found at the base of the stem in compression faucets. Over time, the constant pressure and friction can cause them to harden, crack, or wear down, preventing a proper seal.
Damaged O-Rings: O-rings are small rubber rings that create seals around moving parts, like the stem of the faucet. If an O-ring deteriorates or becomes brittle, water can escape around the stem, causing leaks around the handle or even a drip from the spout.
Corroded Valve Seats: The valve seat is a metal component where the washer presses against to stop water flow. Mineral deposits from water can build up on the valve seat, or it can become corroded, creating an uneven surface that a washer can’t seal against.
Faulty Cartridges: Many modern faucets, including some two-handle models, use cartridges instead of traditional washers and stems. These cartridges contain all the valve components in a single unit. If the cartridge is faulty or worn out, it will need to be replaced entirely.

Tools and Materials You’ll Need

Before you begin your faucet repair, gather the necessary tools and materials. Having everything on hand will make the process smoother and more efficient.

Essential Tools:

Adjustable Wrench: For loosening and tightening nuts.
Phillips Head Screwdriver: For removing handle screws.
Flathead Screwdriver: For prying off decorative caps or stubborn parts.
Pliers (Needle-Nose and Standard): For gripping small parts.
Allen Wrench Set: Some faucet handles have set screws that require Allen wrenches.
Plumber’s Grease (Silicone-Based): To lubricate O-rings and moving parts.
Rag or Towel: To protect the sink basin from dropped parts and for cleaning.
Bucket: To catch any residual water.
Penetrating Oil (Optional): For loosening stubborn parts.
Utility Knife or Small Pry Tool: For removing decorative caps.

Replacement Parts:

Replacement Washers: It’s a good idea to have a variety of common washer sizes on hand, or to take the old one to the hardware store to find an exact match.
Replacement O-Rings: Similar to washers, having a selection or knowing your faucet model will help.
Replacement Cartridge (if applicable): This will be specific to your faucet brand and model.

Step-by-Step Guide to Fixing a Dripping Two Handle Faucet

This guide assumes you have a common compression-style two-handle faucet, which is the most prevalent type. If your faucet has different mechanisms, the exact parts might vary, but the general process of disassembly and replacement will be similar.

Step 1: Shut Off the Water Supply

This is the most crucial first step in any plumbing repair. Look under your sink for the two shut-off valves connected to the hot and cold water lines leading to the faucet. Turn these valves clockwise until they are completely closed.

Testing the Water: Turn on the faucet handles (both hot and cold) to ensure the water is indeed off and to drain any remaining water in the lines. Water should not flow from the spout.

Step 2: Disassemble the Faucet Handle

This is where the DIY faucet fix begins to take shape. You’ll need to remove the faucet handle to access the internal components.

Removing the Faucet Handle:

Locate the Decorative Cap: Most faucet handles have a decorative cap that hides the mounting screw. This cap is usually on top of the handle or on the front side.
Pry Off the Cap: Carefully use a flathead screwdriver or a utility knife to gently pry off this cap. Be patient, as some caps can be tight. Avoid using excessive force that could damage the handle.
Remove the Handle Screw: Once the cap is off, you’ll see a screw. Use the appropriate screwdriver (usually Phillips head) to remove this screw.
Lift Off the Handle: With the screw removed, the handle should lift straight up and off the faucet stem. If it’s stuck, you might need to gently wiggle it or use a bit of penetrating oil on the stem. Some handles have a special “handle puller” tool if they are particularly stubborn, but this is rare for typical home faucets.

Step 3: Accessing the Inner Components

Once the handle is off, you’ll see the faucet stem or cartridge. This is where the problem likely lies.

For Compression Faucets (Washers and Stems):

Unscrew the Packing Nut: Below the handle, you’ll find a hexagonal packing nut. Use your adjustable wrench to unscrew this nut. Turn it counter-clockwise.
Remove the Faucet Stem: Once the packing nut is off, you can usually pull the faucet stem straight up and out. Some stems might need a gentle twist.
Inspect the Washer: At the bottom of the stem, you’ll find a rubber washer held in place by a screw. This is the most common source of drips.
Inspect the O-ring: There may also be an O-ring around the stem itself, above the washer. This O-ring helps prevent leaks around the stem.

For Cartridge Faucets:

Remove the Retaining Clip or Nut: Cartridges are typically held in place by a retaining clip or a threaded nut. You’ll need to identify which one secures your specific cartridge. A small retaining clip often slides into the faucet body and needs to be carefully pried out. A nut will require your adjustable wrench.
Pull Out the Cartridge: Once the clip or nut is removed, you should be able to pull the entire cartridge straight out. Some might require a gentle wiggle. Be sure to note the orientation of the cartridge as you remove it.

Step 4: Replacing Worn Parts

This is the core of your faucet repair. Depending on your faucet type, you’ll be replacing a washer, O-ring, or the entire cartridge.

Replacing Washers and O-Rings (Compression Faucets):

Remove the Old Washer: Use your screwdriver to remove the screw holding the washer at the bottom of the stem. Take off the old washer.
Install the New Washer: Place the new washer onto the stem and secure it with the screw. Make sure it’s seated correctly.
Replace the O-ring: If there’s an O-ring on the stem, carefully remove the old one using a small screwdriver or pick. Lubricate the new O-ring with plumber’s grease and slide it into place.
Reassemble the Stem: Reinsert the stem into the faucet body.
Tighten the Packing Nut: Screw the packing nut back on snugly, but don’t overtighten. This nut helps compress the packing material (if present) and prevent leaks around the stem.

Replacing the Faucet Cartridge:

Match the Cartridge: If you’re replacing a cartridge, it’s essential to get an exact match for your faucet brand and model. Take the old cartridge to a plumbing supply store or hardware store, or look up your faucet model online to order the correct part.
Install the New Cartridge: Carefully insert the new cartridge into the faucet body, ensuring it’s oriented correctly according to the markings or the old cartridge’s position.
Secure the Cartridge: Reinstall the retaining clip or nut to hold the new cartridge in place.

Step 5: Reassembling the Faucet

Now it’s time to put everything back together to complete your kitchen sink repair.

Reattach the Handle: Place the handle back onto the stem or cartridge.
Insert and Tighten the Handle Screw: Secure the handle with the screw you removed earlier.
Replace the Decorative Cap: Snap the decorative cap back into place.

Step 6: Testing Your Repair

The moment of truth!

Turn the Water Supply Back On: Slowly turn the shut-off valves under the sink counter-clockwise to restore the water supply.
Check for Leaks: Turn on the faucet handles (both hot and cold) to check for proper operation. Then, turn them off completely.
Inspect for Drips: Watch the spout and around the handles for any signs of leaking. If the drip is gone, congratulations on a successful DIY faucet fix!

Troubleshooting Common Issues During Faucet Repair

Even with careful work, you might encounter a few snags. Here’s how to handle them.

Handle Still Drips After Repair:

Check the Washer/Cartridge: Ensure the new washer is the correct size and seated properly, or that the new cartridge is fully inserted and correctly aligned.
Inspect the Valve Seat: If you have a compression faucet and replaced the washer but still have a drip, the valve seat might be the problem. This requires a special tool called a “valve seat dresser” or “seat wrench” to either resurface or replace the seat. If it’s badly corroded, you might need to replace the entire faucet.
Packing Nut Tightness: The packing nut might need slight adjustment. Try tightening it a quarter turn at a time to see if it stops minor leaks around the stem.
Damaged Faucet Body: In rare cases, the faucet body itself might be cracked or damaged, requiring faucet replacement.

Leaks Around the Handle:

O-ring Issue: A damaged or improperly installed O-ring is the usual suspect. Ensure the O-ring is the correct size and lubricated.
Packing Nut: If your faucet has a packing nut, it might not be tightened enough to compress the packing material or O-ring adequately.

Difficulty Removing Parts:

Mineral Buildup: Hard water can cause parts to fuse. A penetrating oil can help loosen corroded threads. Let it sit for a while before trying again.
Gentle Persuasion: Sometimes, a bit of gentle tapping with the handle of your screwdriver can help dislodge stuck parts.

When to Call a Professional Plumber

While many faucet repair jobs are DIY-friendly, there are times when it’s best to call in a professional.

Uncertainty: If you’re unsure about any step or can’t identify the problem, a professional can diagnose and fix it efficiently.
Specialized Tools Needed: If your faucet requires specialized tools that you don’t have and don’t want to purchase (like a valve seat dresser or a specific handle puller).
Persistent Leaks: If you’ve attempted repairs and the leak persists, it might indicate a more complex issue.
Corroded or Damaged Faucet: If the faucet body itself is corroded, cracked, or heavily damaged, replacement might be the most practical solution, and a plumber can handle this.
Lack of Time or Confidence: If you simply don’t have the time or the confidence to tackle the repair, hiring a plumber is a sensible choice.

Faucet Anatomy: Understanding the Components

To better perform your DIY faucet fix, it’s helpful to know the basic parts of a two-handle faucet.

Retaining Clip/Nut	Secures the cartridge in place within the faucet body.	Holds the cartridge firmly in its position.
Spout	The part of the faucet from which water flows.	Directs the water into the sink basin.
Aerator	A small screen at the tip of the spout that mixes air with water.	Creates a smooth, splash-free stream and conserves water.

Common Faucet Brands and Their Specifics

While this guide provides general steps, different faucet brands (like Moen, Delta, Kohler, Price Pfister) may have slightly different designs for their internal mechanisms and replacement parts.

Moen: Often uses cartridges that are secured with a retaining clip. They are known for their quarter-turn ceramic disc cartridges in some models.
Delta: Many Delta faucets use a “diamond seal” technology, often involving cartridges with ceramic discs. Their handles are typically secured by a screw under a decorative cap.
Kohler: Similar to others, Kohler uses various cartridge types. Some older models might use compression stems and washers, while newer ones employ cartridges.
Price Pfister: May utilize both compression and cartridge designs. Pay close attention to how the handle and internal components are secured.

Tip: Always try to identify your faucet’s brand and model. This information is usually found on the faucet itself (often on the underside of the spout or on the back of the faucet body) or in your home’s original documentation. Having this information will make finding replacement parts much easier and ensure a successful faucet repair.

Frequently Asked Questions (FAQ)

Here are some common questions people have when dealing with a dripping faucet:

Q: How often should I replace faucet washers?
A: Faucet washers don’t have a fixed replacement schedule. They need replacement when they show signs of wear, such as hardening, cracking, or causing leaks. This can be anywhere from a few years to over a decade, depending on water quality and usage.
Q: My faucet still drips after I replaced the washer. What else could it be?
A: If you have a compression faucet and the drip persists after replacing the washer, the most likely culprit is a worn or damaged valve seat. You’ll need to address the valve seat either by resurfacing it with a valve seat dresser tool or by replacing it entirely. If it’s severely damaged, the faucet might need replacement.
Q: Is it normal for a new faucet cartridge to be stiff?
A: A new cartridge might feel a bit stiff when you first install it, but it should loosen up with use. If it’s extremely difficult to turn or operate, double-check that it’s correctly installed and aligned.
Q: Can I use plumber’s tape on faucet threads?
A: Plumber’s tape (PTFE tape) is typically used on threaded pipe connections to create a watertight seal. For faucet handle assemblies and cartridges, it’s generally not recommended. Lubricating O-rings with plumber’s grease is the correct method to ensure proper sealing and ease of operation.
Q: How do I know if I have a compression faucet or a cartridge faucet?
A: Compression faucets usually require multiple turns of the handle to go from off to fully on, and you’ll feel resistance as you turn. Cartridge faucets often turn on and off with a quarter or half turn, and the handle movement feels smoother. You can also tell by disassembling the handle: if you find a stem with a washer at the bottom, it’s a compression faucet. If you pull out a single, self-contained unit, it’s a cartridge.

By following these steps, you can confidently tackle a dripping two-handle kitchen faucet, saving yourself money and the hassle of a constant drip. Remember to work patiently, use the right tools, and don’t hesitate to consult a professional if you encounter any issues beyond your comfort level.
