Why Fix It Yourself?

A dripping faucet might seem like a minor annoyance, but even a slow drip can waste a significant amount of water over time — and it only gets worse if ignored. The good news: most faucet leaks are caused by a worn washer or O-ring, and fixing them requires no plumbing experience, just a few basic tools and about an hour of your time.

What You'll Need

  • Adjustable wrench or pliers
  • Flat-head and Phillips screwdrivers
  • Replacement washers, O-rings, or cartridge (matched to your faucet type)
  • Plumber's grease (optional but helpful)
  • Towel and small bucket

Step 1: Identify Your Faucet Type

There are four main types of faucets, and the repair method differs slightly for each:

  • Ball faucet: Single handle that rotates over a rounded cap (common in kitchens)
  • Cartridge faucet: Single or double handle with a cartridge inside
  • Ceramic disc faucet: Single lever over a wide cylindrical body
  • Compression faucet: Two separate handles that you tighten to turn off (older style)

Most modern faucets are cartridge or ceramic disc types. Compression faucets are found in older homes and are among the easiest to fix.

Step 2: Turn Off the Water Supply

Look under the sink for the shut-off valves — one for hot, one for cold. Turn them clockwise until they stop. If there are no individual shut-offs, turn off the main water supply for the home. Turn on the faucet to drain any remaining water and release pressure.

Step 3: Remove the Faucet Handle

Look for a decorative cap on top of the handle — it often pops off with a flat-head screwdriver to reveal a screw underneath. Remove the screw and gently pull the handle straight off. If it's stiff, wiggle gently rather than forcing it.

Step 4: Find and Replace the Worn Part

For Compression Faucets

Once the handle is off, unscrew the packing nut with a wrench and pull out the stem. At the bottom you'll find a rubber washer held by a brass screw — this is almost always the culprit. Replace it with an identical washer, reassemble, and test.

For Cartridge Faucets

After removing the handle, pull out the cartridge (note which way it's oriented). Take it to a hardware store to match the exact replacement. Insert the new cartridge in the same direction, reassemble, and test.

For Ceramic Disc Faucets

Remove the disc cylinder and inspect the ceramic discs. Clean them with white vinegar if they're dirty. If cracked or chipped, replace the entire cylinder.

Step 5: Reassemble and Test

Reverse the disassembly steps to put everything back together. Turn the water supply back on slowly. Test the faucet for leaks — if it drips, double-check that all parts are properly seated and tightened.

When to Call a Plumber

If the leak is at the base of the faucet (not the spout), involves corroded pipes, or returns quickly after your repair, it may be time to call a professional. DIY repairs work well for common drips — but know your limits.

Final Thought

Fixing a leaky faucet is one of the most beginner-friendly home repairs you can tackle. With the right replacement part and a bit of patience, you can solve the problem in a single afternoon.
