A Step-by-Step Guide to Fixing a Leaky Faucet

A dripping faucet is more than just an annoyance; it's a drain on your wallet and a waste of a precious resource. That persistent drip… drip… drip… can waste hundreds of gallons of water a year, significantly increasing your water bill. The good news is that fixing a leaky faucet is one of the most common and manageable DIY plumbing projects. With the right tools, a little patience, and this step-by-step guide, you can silence the drip and restore peace to your home.

Why You Should Fix a Leaky Faucet Immediately

Before we dive into the repair process, it's important to understand why this isn't a problem you should ignore. A faucet leak, even a small one, has consequences that extend beyond the sound.

• Water Waste: According to the EPA, a single faucet leaking at one drip per second can waste more than 3,000 gallons of water per year. That's enough for over 180 showers!
• Increased Bills: All that wasted water isn't free. A leaky faucet can add hundreds of dollars to your annual water and energy bills if hot water is involved.
• Potential for Damage: Constant dripping can lead to stains, damage to your sink and fixtures, and the growth of mold and mildew.
• Wear and Tear: The leak indicates an internal part has failed. Leaving it unrepaired can cause more extensive damage to the faucet's valve seat or other components, leading to a more costly repair down the line.

Gather Your Tools and Materials

Preparation is key to a smooth and successful repair. There's nothing worse than being halfway through a project and realizing you're missing a crucial tool. Lay everything out on a towel inside the sink basin to prevent small parts from disappearing down the drain.

Essential Tools:

• Adjustable Wrench or Basin Wrench
• Slip-Joint Pliers
• Hex (Allen) Keys
• Screwdrivers (Flat-head and Phillips)
• Old Toothbrush or Small Brush

Essential Materials:

• Replacement Washers, O-rings, and/or Cartridge/Seats (often found in a universal faucet repair kit)
• Plumber's Grease
• White Vinegar (for cleaning)
• Clean Rags or Towels

Pro Tip: Before you start, take a picture of the faucet's assembly with your phone as you disassemble it. This will serve as a perfect reference for reassembly.

Step 1: Turn Off the Water Supply

This is the most critical safety step. Never attempt to disassemble a faucet with the water supply on.

1. Locate the water shut-off valves under the sink. There should be two: one for hot water (usually on the left) and one for cold (usually on the right).
2. Turn the handles clockwise until they stop. Do not force them; if they are stuck, use your pliers gently.
3. Turn the faucet handles on to release any remaining water pressure in the lines. Once the water stops flowing, you can be confident the supply is off.

Important Note: If you cannot find or operate the shut-off valves under the sink, you may need to turn off the main water supply to your entire house.

Step 2: Disassemble the Faucet

The disassembly process varies depending on your faucet type (compression, cartridge, ball, or ceramic disk). We'll cover the most common types.

For a Compression Faucet (Two Separate Handles for Hot and Cold):

1. Pry off the decorative cap on the handle (often labeled "H" or "C") with a flat-head screwdriver.
2. Unscrew the handle screw and lift the handle off the stem.
3. Use your wrench to unscrew the packing nut. You will now see the stem assembly.
4. Lift the stem out. At the bottom, you will find a washer held in place by a screw. This is the most common culprit for leaks.

For a Single-Handle Cartridge Faucet (Common in Modern Homes):

1. Look for a small set screw under a lever or behind a decorative cap. Remove it with an Allen key or screwdriver.
2. Lift the handle off to expose the cartridge and retaining clip.
3. Remove the retaining clip carefully with pliers or a screwdriver.
4. Pull the cartridge straight out. You may need to use pliers gently, wiggling it back and forth. This cartridge is likely the source of the leak.

Step 3: Identify the Problem and Replace Parts

With the faucet disassembled, inspect the parts. Look for signs of wear, corrosion, cracking, or warping.

• Worn Washers: In compression faucets, a worn or torn rubber washer is the #1 cause of dripping. Replace it with an exact match from your repair kit.
• Faulty O-rings: These small rings create a seal around moving parts. If they are cracked, brittle, or flattened, replace them. Coat new O-rings with plumber's grease before installing.
• Damaged Cartridge: For cartridge and ceramic disk faucets, the entire unit often needs replacement. Take the old cartridge to the hardware store to ensure you get an identical model.
• Corroded Valve Seat: The valve seat is where the washer presses down to form a seal. If it's corroded, it will prevent a tight seal even with a new washer. You can clean it with vinegar or use a special valve seat wrench to replace it.

Clean all non-rubber parts with vinegar and your brush to remove any mineral deposits before reassembling.

Step 4: Reassemble and Test the Faucet

This is simply the reverse of the disassembly process, guided by the photos you took earlier.

1. Carefully place the new or cleaned parts back into the faucet body.
2. Reinstall the stem or cartridge, ensuring it is seated correctly.
3. Replace the retaining nuts and clips, tightening them firmly by hand and then giving them a final quarter-turn with a wrench. Avoid over-tightening, as this can damage the new parts and threads.
4. Place the handle back on and secure it with its screw and decorative cap.

Now for the moment of truth:

1. Slowly turn the water supply valves back on.
2. Turn the faucet handle on and let the water run for a minute. This flushes out any debris that may have been disturbed.
3. Check for leaks around the handles and spout. If you see a leak, turn the water back off and check that all components are seated properly and that you haven't cross-threaded any parts.

When to Call a Professional Plumber

While many faucet leaks are a perfect DIY project, some situations call for expert help. Don't hesitate to call a professional if you encounter any of the following:

• You cannot locate or turn off the water supply.
• The faucet is very old, and you can't find replacement parts.
• There is significant corrosion, and parts are breaking as you try to remove them.
• You've replaced the washers or cartridge, but the faucet still leaks.
• You notice water leaking from the base of the faucet or from pipes under the sink, indicating a more serious issue.
• You simply don't feel comfortable performing the repair yourself.
