What You'll Need

Tools

  • Adjustable Wrench ($10–$20 at Home Depot): This tool is essential for loosening and tightening the nuts that hold your faucet together. An adjustable wrench can fit various sizes, making it versatile for different faucet types. It provides the grip and leverage needed to handle stubborn nuts without damaging them.

  • Screwdriver Set ($5–$15 at Amazon): You'll need a Phillips or flat-head screwdriver depending on your faucet type. Ensure you have a set with multiple sizes to avoid stripping the screws, which can make future repairs difficult. A good screwdriver set is an investment that will serve you well in many DIY projects. Screwdriver Set on Amazon

  • Needle-Nose Pliers ($8–$14 at Lowe's): These are perfect for reaching into tight spaces and can help you grip small parts like the faucet washer itself. Their long, slender shape is ideal for precision work where your fingers can't reach. Needle-Nose Pliers on Lowe's

  • Plumber's Tape ($2–$5 at Amazon): While not always necessary, plumber's tape can help ensure a watertight seal when you reassemble your faucet. It prevents leaks at threaded joints and is a must-have in any DIY toolkit. Plumber's Tape on Amazon

Materials

  • Replacement Washer ($1–$3 at Home Depot): The star of this fix. Make sure to get the correct size and type for your faucet. Most washers are rubber, but some are made of silicone for longer wear. The right washer ensures a snug fit, crucial for stopping leaks. Replacement Washer on Home Depot

  • Silicone Grease ($4–$7 at Lowe's): A small dab of this can lubricate the washer and prolong its life by reducing friction. It forms a moisture-resistant barrier that helps prevent corrosion and sticking. Silicone Grease on Lowe's

Step-by-Step Process

1. Turn Off the Water Supply

First things first, locate the shut-off valves under your sink. Turn them clockwise to stop the water flow. This step is crucial to prevent any accidental spraying or flooding while you're working. A common pitfall here is forgetting to do this, which can lead to a wet mess and potentially damage your cabinets or flooring. Make sure to also turn off the main water supply if your faucet doesn't have individual shut-off valves. Time estimate: 2 minutes.

2. Remove the Faucet Handle

Use your screwdriver to remove the handle of the faucet. Most faucets have a decorative cap that conceals the screw. Pry it off gently with a flat-head screwdriver. This exposes the screw holding the handle in place. Carefully unscrew it and remove the handle. Be cautious not to lose the screw or damage the threads. If the handle is stuck, a gentle wiggle should loosen it. Forcing it off can cause damage. Time estimate: 5 minutes.

3. Extract the Valve Stem

With the handle removed, use your adjustable wrench to unscrew the packing nut. Once the nut is off, you can pull out the valve stem. It's crucial to remove this piece to access the washer underneath. Avoid forcing it out, as you can damage the threads or the valve itself, leading to a more extensive repair. If the stem is difficult to remove, try applying a bit of penetrating oil and letting it sit for a few minutes to loosen any corrosion. Time estimate: 5 minutes.

4. Replace the Washer

Now that you have access to the washer, use your needle-nose pliers to remove the old, worn-out washer. It's often seated in a small recess, so ensure you remove it entirely. Install the new washer by placing it into the seat. Ensure it's the correct size and fits snugly. A common mistake is using the wrong size washer, which won't stop the leak and might even worsen it. Consider applying a small amount of silicone grease to the washer before installing it to ensure a smooth operation. Time estimate: 10 minutes.

5. Reassemble the Faucet

With the new washer in place, reverse your steps. Insert the valve stem back into the faucet body, screw on the packing nut, and replace the handle. Use the plumber's tape if necessary to ensure a tight seal, especially if you're reusing old threads that might be slightly worn. Make sure everything is secured but not over-tightened to avoid damaging any parts. Over-tightening can strip threads and lead to leaks, so ensure a firm but gentle touch. Time estimate: 10 minutes.

6. Test the Faucet

Finally, turn the water supply back on and test your faucet. Turn it on and off to ensure the leak has stopped. If you still notice a drip, double-check your assembly and washer installation. A common oversight is not properly seating the washer, leading to continued leaks. Test the faucet under full pressure to make sure everything is holding up. If the leak persists, it might be an indication of a deeper issue, such as a worn valve seat. Time estimate: 5 minutes.

Common Mistakes

  • Using the Wrong Washer Size: This is the most common error and can lead to continued leaks. Always double-check the size before purchasing. Measure the old washer and bring it with you to the hardware store to ensure a perfect match. An incorrect size can cause water to bypass the washer entirely.

  • Over-Tightening: While it's important to ensure a tight fit, over-tightening can damage components, especially the valve seat, leading to further leaks. It can also make future repairs more difficult, as over-tightened parts can become stuck and hard to remove.

  • Skipping the Water Supply Shut-off: Failing to turn off the water supply can result in a messy situation, with water spraying uncontrollably. This not only creates a cleanup hassle but can also lead to water damage. Always double-check that the water is fully off before starting your work.

  • Neglecting to Check for Corrosion: When you've got the faucet disassembled, take a moment to inspect the valve seat and other components for corrosion or damage. Ignoring these signs can lead to future problems that could have been easily addressed with a bit of preventative maintenance.

Safety

  • Mind Your Fingers: When using tools like wrenches and pliers, be cautious of pinching or cutting your fingers. Always handle tools with care and ensure you have a firm grip to avoid accidents.

  • Water and Electricity Warning: Ensure no electrical devices are nearby when you're working under the sink, as water and electricity don't mix well. This is especially important if your sink is near a power outlet. If you're unsure, consult OSHA's electrical safety guidelines.

  • Wear Eye Protection: Small parts and tools can create debris; wearing safety goggles can protect your eyes from unexpected splashes or flying particles.

When to Call a Pro

If you've replaced the washer and the faucet is still dripping, or if you notice corrosion or damage in the faucet components, it may be time to call a professional plumber. Persistent leaks can indicate issues beyond a simple washer replacement, such as a worn-out valve seat or a need for a complete faucet replacement. Additionally, if you're uncomfortable with the disassembly process or run into unforeseen complications, professional help can save you time and prevent further damage.
