A leaky faucet isn’t just annoying—it can waste hundreds of gallons of water a year and increase your utility bill. The good news? You don’t need to be a plumber to fix it.

In this step-by-step guide, you’ll learn how to fix a leaky faucet in under 30 minutes using a few simple tools. Whether your kitchen faucet drips or your bathroom tap won’t stop leaking, this DIY tutorial has you covered.

Step 1: Identify the Type of Faucet You Have

Not all faucets are built the same, and the repair method depends on the type.

There are four main types of faucets:

  • Compression – Has two handles (hot and cold). Common in older homes.
  • Cartridge – Moves up/down and left/right. Often found in modern bathrooms.
  • Ball – Usually a single handle. Common in kitchen sinks.
  • Ceramic Disc – Also single handle. Durable and high-end.

Why it matters: The type of faucet determines which parts might be worn out (washer, O-ring, cartridge) and how to disassemble it.

Step 2: Gather the Right Tools and Replacement Parts

Before you start fixing the leak, gather the following tools:

  • Adjustable wrench
  • Phillips and flathead screwdrivers
  • Plumber’s tape (Teflon tape)
  • Replacement washers, O-rings, or cartridges (based on faucet type)
  • Towel or rag
  • Small bowl (to hold tiny parts)

💡 Pro Tip: Take the old part to a hardware store to find an exact replacement.

Step 3: Turn Off the Water Supply and Prep the Area

This is the most crucial safety step!

  1. Look under your sink for shut-off valves (usually two: hot and cold).
  2. Turn both valves clockwise to shut off the water supply.
  3. Open the faucet to release pressure and drain water from the lines.
  4. Place a towel or rag in the sink to catch small parts and prevent scratches.

🔎 Step 4: Disassemble the Faucet and Inspect for Damage

Now the fun begins.

  1. Use a flathead screwdriver to pry off the decorative cap on the faucet handle.
  2. Unscrew the handle and gently remove it.
  3. Use your wrench to loosen and remove the packing nut.
  4. Pull out the valve stem or cartridge (depends on faucet type).

What to look for:

  • Worn-out washer or O-ring (usually the cause in compression faucets)
  • Damaged cartridge or seals (in cartridge or ceramic disc faucets)
  • Corrosion or mineral buildup

Step 5: Replace the Faulty Parts and Reassemble

Once you’ve identified the issue:

  1. Replace the worn washer, O-ring, or cartridge.
  2. Apply plumber’s tape to threads if needed to prevent future leaks.
  3. Reassemble everything in reverse order:
    • Insert the stem or cartridge
    • Tighten the packing nut
    • Reattach the handle and cap
  4. Turn the water valves back on slowly and test the faucet.

Bonus Tips: Prevent Future Leaks
