Fixing a minor leak in washroom faucets

Fixing a slowly leaking washroom faucet typically involves identifying the type of faucet and replacing worn components like washers, O-rings, or cartridges. Here’s a step-by-step guide:


1. Gather Tools and Supplies

You’ll need:

  • Adjustable wrench

  • Screwdrivers (flathead and Phillips)

  • Replacement parts (e.g., washers, O-rings, cartridge)

  • Plumber’s tape

  • Bucket or towel

  • Cleaning supplies (vinegar, cloth)


2. Turn Off the Water Supply

  • Locate shut-off valves: These are usually under the sink. Turn them clockwise to shut off the water.

  • Test the faucet: Open it to ensure the water supply is fully off and to release any remaining water pressure.


3. Plug the Drain

  • Prevent small parts from falling: Use a sink plug or a cloth to cover the drain.


4. Identify the Type of Faucet

  • Common types: Compression, ball, cartridge, or ceramic disk.

  • Understanding the type helps you know which parts to check and replace.


5. Disassemble the Faucet

  1. Remove decorative caps: Pry off any caps on the handle using a flathead screwdriver.

  2. Unscrew the handle: Use a screwdriver to remove screws holding the handle, then lift it off.

  3. Access the internal components: Depending on the faucet type, this may involve removing a retaining nut or other parts with an adjustable wrench.


6. Inspect and Replace Components

  • Compression faucets: Replace worn washers or O-rings on the valve stem.

  • Cartridge faucets: Pull out the cartridge and replace it if it's damaged or worn.

  • Ball faucets: Replace seals and springs inside the valve.

  • Ceramic disk faucets: Check and replace the rubber seals.


7. Clean the Faucet Components

  • Remove debris: Clean components with vinegar or a cloth to remove limescale and sediment.

  • Inspect for wear: Ensure all parts are in good condition or replace them.


8. Reassemble the Faucet

  • Reinstall the components in reverse order.

  • Tighten parts securely but avoid over-tightening, which can cause damage.


9. Turn On the Water Supply

  • Test for leaks: Slowly open the shut-off valves and turn on the faucet.

  • Check functionality: Ensure the leak is resolved and the faucet operates smoothly.


10. Additional Tips

  • Keep spare parts handy: Many leaks are caused by minor wear and tear.

  • Use plumber’s tape: Wrap threads with tape to ensure a tight seal when reassembling.

  • Call a professional if needed: If the leak persists or the repair seems complex, consider hiring a plumber.
