How to Fix a Leaky Faucet DIY Guide
Stop annoying drips and save water by learning how to fix a leaky faucet yourself. This step-by-step DIY guide helps you identify and replace common worn parts quickly and safely.
Quick Summary
A persistent drip from your faucet can be both irritating and wasteful, but often it's a simple issue you can fix yourself. Most common faucet leaks stem from worn-out washers, O-rings, or seals that are easy to replace with standard household tools.

🛒 What You Need
- Screwdriver (Phillips and flathead)
- Adjustable wrench
- Pliers
- Replacement washers/O-rings (kit or specific to faucet model)
- Plumber's grease (silicone-based)
- Rag or towel
- Small bucket or bowl
📋 Steps
Turn Off the Water Supply
Locate the shut-off valves under the sink and turn them clockwise until the water flow stops completely. Once the valves are closed, turn on the faucet to drain any remaining water in the lines, which helps relieve pressure and prevents unexpected splashes. Ensure the water is completely off before proceeding to the next step.
Cover the Drain and Prepare
Place a rag or towel over the drain opening to prevent small screws or parts from falling down and getting lost during the repair. Use a flathead screwdriver or a small pry tool to gently remove any decorative caps on the faucet handles, exposing the screws underneath. Keep a small container nearby for holding these tiny components.
Disassemble the Faucet Handles
Using the appropriate screwdriver, remove the screws holding the faucet handles in place. Carefully lift the handles off the faucet body. Depending on your faucet model, you might then need to remove a decorative escutcheon or dome that covers the internal components. Pay attention to how each piece is oriented as you remove it.

Remove the Cartridge or Stem
Once the handles are off, you will see the faucet cartridge or stem assembly. Use an adjustable wrench or pliers to carefully unscrew and remove this component. It's crucial to note its exact orientation (e.g., which way it's facing) before you pull it out, as it must be reinserted in the same position for proper function.
Inspect and Replace Worn Parts
Examine the removed cartridge or stem for any visible signs of wear, such as cracked, flattened, or brittle rubber washers and O-rings. Replace these worn parts with new ones from your repair kit, ensuring they precisely match the original size and type. Apply a thin, even coat of plumber's silicone grease to any new O-rings to ensure a smooth fit and a watertight seal.
Reassemble the Faucet
Carefully reinsert the new or repaired cartridge or stem into the faucet body, making sure it's correctly oriented as you noted during disassembly. Hand-tighten it initially, then use your wrench to secure it, but do not overtighten, as this can damage the components. Replace any decorative escutcheons, then reattach the handles and secure them with their screws.
Restore Water Supply and Test
Slowly turn the water supply valves back on counter-clockwise under the sink. Turn them on gradually to avoid startling pressure surges. Once the water is fully restored, check thoroughly for any leaks around the faucet base, handles, or spout. Turn the faucet on and off several times to ensure it's functioning correctly and that the annoying drip has finally stopped.
💡 Tips & Tricks
- Always use plumber's silicone grease for O-rings; other greases can damage rubber.
- When buying replacement parts, it's helpful to know your faucet's brand and model, or bring the old part with you.
- Consider replacing both hot and cold-side washers/O-rings even if only one is leaking, as they are likely the same age and condition.

⚠️ Warnings
- ⚠️ Always turn off the water supply before attempting any faucet repair to prevent flooding.
- ⚠️ Do not apply excessive force when tightening components, as this can strip threads, crack plastic parts, or damage the faucet.
- ⚠️ Be cautious with old plumbing; corroded pipes or valves can sometimes break when manipulated.

❓ Frequently Asked Questions
Why is my faucet still dripping after replacing the washer?
If your faucet continues to drip after replacing the washer, the issue might be a worn-out O-ring, a damaged valve seat, or corrosion inside the faucet body. Double-check all seals and ensure the valve seat is smooth and free of debris.
How do I know what type of faucet I have?
Common faucet types include compression, cartridge, ceramic disc, and ball faucets. You can often identify your type by how the handle operates or by researching your faucet's brand and model online, which helps in finding the correct replacement parts.
What if the shut-off valves under the sink are stuck?
If the shut-off valves are stuck, try applying a penetrating oil and gently wiggling them with a wrench. If they still won't turn, it's safer to shut off the main water supply to your house before proceeding with the faucet repair to avoid potential damage or leaks.
Can I use any type of grease for the O-rings?
No, it's crucial to use plumber's silicone grease. Other types of grease, like petroleum jelly or automotive grease, can degrade rubber O-rings over time, causing them to swell or break down, which will lead to new leaks.
My faucet is leaking from the base, not the spout. How can I fix that?
A leak from the base of the faucet often indicates a problem with the O-rings at the base of the spout itself or the mounting nuts underneath the sink that secure the faucet. You may need to remove the spout or tighten the mounting nuts to resolve this issue.
Is it better to repair or replace an old faucet?
For minor, easily identifiable leaks, repairing an old faucet is usually cost-effective. However, if the faucet is very old, heavily corroded, or constantly developing new leaks, replacing it might be a more practical and long-term solution to avoid recurring problems.
How can I prevent future faucet leaks?
To prevent future faucet leaks, regularly clean your faucet, avoid overtightening the handles, and consider having your home's water pressure checked if it's excessively high. High water pressure can prematurely wear out faucet components like washers and O-rings.
