How do you fix a leaky faucet effectively?

To fix a leaky faucet effectively, follow these steps:

1. Shut Off the Water and Prepare

• ·Turn off the water supply valves under the sink or the main water supply if necessary.
• ·Drain residual water by opening the faucet handles.
• ·Close the drain and place a towel in the sink to catch small parts.
• ·Remove the aerator from the spout; if stuck, soak it in vinegar.

2. Disassemble the Faucet

• ·Remove the handle:
  • ·Pry off any decorative caps with a flathead screwdriver.
  • ·Unscrew the handle screw and remove the handle (wiggle gently if stuck).
• ·Expose the inner mechanism:
  • ·For cartridge faucets, remove the retaining clip/nut and pull out the cartridge.
  • ·For stem faucets, loosen the packing nut with a wrench and lift out the stem.

3. Diagnose and Repair

• ·Common causes of leaks:
  • ·Worn washers: Replace the rubber washer at the base of the stem.
  • ·Damaged O-rings: Lubricate new O-rings with plumber’s grease before reinstalling.
  • ·Corroded valve seats: Replace if pitted or use a seat wrench to remove buildup.
  • ·Faulty cartridges: Replace if internal seals are worn.
  • ·Mineral deposits: Soak parts in white vinegar to dissolve buildup.

4. Reassemble and Test

• ·Reinstall parts, ensuring proper alignment and gentle tightening (avoid overtightening).
• ·Apply Teflon tape to exposed threads if needed.
• ·Turn water back on slowly and flush the system to clear debris.
• ·Reattach the aerator and test for leaks.

Tools Needed

• ·Adjustable wrench, flathead screwdriver, plumber’s grease, replacement washers/O-rings/cartridges (as required).
