How To Fix a Leaking Bathroom Faucet

A leaky faucet is far more than just an annoying sound. It can waste water, potentially causing higher utility bills, and lead to water damage over time. Fortunately, fixing a leaking bathroom faucet is a relatively simple DIY project for most homeowners. With the right tools and a little patience, you can stop the drip and save yourself money and stress.

Step 1: Identify the Leak Type

Before you begin any repairs, it is important to identify the source of the leak. This will determine what type of repair is necessary.

Common leak types:

Leaking Cartridge: The most common type of leak, caused by a worn-out or damaged cartridge. This often results in a constant drip or a slow, steady stream of water.
Leaking Washer: Another common issue where a worn-out or damaged washer around the faucet stem causes a drip when the faucet is turned off.
Leaking O-Ring: Located within the faucet, a damaged O-ring can cause leaks at the spout or handles.
Loose or Worn-Out Packing Nut: This can cause leaks at the base of the faucet spout.

Step 2: Gather Your Tools and Materials

Before you begin, gather the necessary tools and materials:

Adjustable wrench
Channel-lock pliers
Phillips screwdriver
Flathead screwdriver
Basin wrench (if needed)
Replacement cartridge, washer, O-ring, or packing nut (depending on the leak type)
Plumber's tape
Bucket or towel to catch any water

Step 3: Turning Off the Water Supply

Safety is paramount. Before you start, turn off the water supply to the faucet. This is usually done by locating the shut-off valves beneath the sink or in the basement. Make sure the valve is completely closed.

Step 4: Disassembling the Faucet

The process will vary depending on the type of faucet, but generally involves these steps:

Remove the handle/handles: Using the appropriate screwdriver, remove the screws holding the handle or handles in place.
Remove the faucet stem: The stem holds the cartridge and washer. Use a wrench or pliers to loosen the stem, carefully removing it from the faucet body.
Remove the cartridge or washer: Once the stem is out, you can remove the cartridge or washer depending on the specific leak type.

Step 5: Replace the Damaged Part

After removing the damaged part, replace it with a new one. Make sure to use the correct replacement part, matching the size and type of your existing faucet.

Step 6: Reassemble the Faucet

Follow these steps to put the faucet back together:

Install the new cartridge or washer: Place the new part securely on the stem.
Reinstall the stem: Carefully screw the stem back into the faucet body. Tighten it using the wrench or pliers, but avoid overtightening to prevent damage.
Reinstall the handle/handles: Replace the handle or handles and tighten the screws.
Turn on the water supply: Slowly turn the water supply back on, checking for any leaks.

Step 7: Test for Leaks

Turn on the faucet and run the water for a few minutes. Check for any leaks from the base of the faucet, the spout, or the handle. If you notice leaks, you may need to tighten the stem, re-install the replacement part, or check for other worn-out parts.
