Step-by-Step Guide to Fixing a Leaky Faucet

  1. Identify the Type of FaucetThere are four common types of faucets: compression, ball, cartridge, and ceramic disk. Identifying your faucet type is crucial as it determines the parts you need to replace.
  2. Turn off the water supply. Locate the shutoff valves under the sink and turn them off. If your sink doesn’t have shutoff valves, turn off the main water supply to your home. Open the faucet to release any remaining water in the lines.
  3. Plug the drain. Use a sink plug or a rag to block the drain. This prevents small parts from falling down the drain while you’re working.
  4. Disassemble the Faucet
    • For Compression Faucets: Remove the decorative cap on the handle, unscrew the handle, and use an adjustable wrench to loosen and remove the packing nut. Remove the stem, and inspect the O-ring and washer.
    • For Ball Faucets: Use an Allen wrench to remove the handle, then use pliers to remove the cap and collar. Extract the ball assembly and check the inlet seals and springs.
    • For Cartridge Faucets, Remove the handle and use pliers to remove the retaining clip holding the cartridge in place. Then, pull out the cartridge.
    • For Ceramic Disk Faucets, Remove the handle and unscrew the escutcheon cap. Then, lift out the cylinder and check the seals.
  5. Inspect and Replace Damaged Parts. Examine the parts for signs of wear and tear. Worn-out washers, O-rings, and seals are common culprits of leaks. Replace these parts with new ones, which can be found at most hardware stores.
  6. Clean the Components: Clean the faucet’s interior components and the valve seat with vinegar to remove any mineral buildup. This helps ensure a proper seal when you reassemble the faucet.
  7. Reassemble the Faucet
    • For Compression Faucets: Reinstall the stem, replace the packing nut, and reattach the handle.
    • For Ball Faucets, Replace the ball assembly, springs, and inlet seals. Then, reattach the collar and cap, followed by the handle.
    • For Cartridge Faucets: Insert the new cartridge, replace the retaining clip, and reattach the handle.
    • For Ceramic Disk Faucets: Reinstall the cylinder and reattach the escutcheon cap and handle.
  8. Turn on the Water Supply. Turn the water supply back on gradually to avoid sudden pressure changes that could damage the faucet. Then, open the faucet and inspect the repaired area for leaks.
  9. Test the faucet. Run the water and check for any leaks. Ensure the faucet operates smoothly without any drips.
