how to fix a kitchen faucet that won’t turn off

A kitchen faucet that won’t turn off can be not only frustrating but also a potential source of water waste and increased utility bills. Here’s a step-by-step guide to help you fix a kitchen faucet that won’t turn off:

Materials You May Need:

  1. Adjustable Wrench: To loosen and tighten connections.
  2. Replacement Cartridge or Parts (if necessary): Depending on the type of faucet.
  3. Plumber’s Tape (Teflon Tape): For sealing threaded connections.


  1. Turn Off the Water Supply:
    • Locate the shutoff valves under the sink or at the main water supply for the kitchen. Turn off the water supply by turning the valves clockwise until they are fully closed.
  2. Release Pressure:
    • To avoid any sudden water release, turn on the faucet and allow any remaining water to flow out until it stops completely. This relieves pressure in the system.
  3. Remove the Faucet Handle:
    • Depending on your faucet type, use a screwdriver or Allen wrench to remove the handle. Most handles are secured with a screw that’s typically located under a decorative cap or cover.
  4. Inspect the Cartridge or Valve:
    • Once the handle is removed, you’ll have access to the faucet’s cartridge or valve assembly. Inspect it for any visible damage or signs of wear.
  5. Replace the Cartridge or Valve (if necessary):
    • If the cartridge or valve appears damaged, you may need to replace it. Consult the manufacturer’s documentation or take a photo of the existing cartridge to help you find the correct replacement at a hardware store.
  6. Use Plumber’s Tape (if necessary):
    • If you’ve replaced any parts or disassembled the faucet, apply plumber’s tape (Teflon tape) to the threaded connections to ensure a tight seal when reassembling.
  7. Reassemble the Faucet:
    • Carefully reassemble the faucet in the reverse order of how you took it apart. Ensure that all parts are securely in place.
  8. Turn On the Water Supply:
    • Slowly turn on the water supply by turning the shutoff valves counterclockwise. Be prepared for some water to flow initially as the air is released from the pipes.
  9. Test the Faucet:
    • Turn on the faucet and check if the issue has been resolved. The faucet should now turn on and off smoothly without any leaks.
  10. Check for Leaks:
    • Look for any signs of leaks around the faucet, connections, or under the sink. If you notice any leaks, tighten the connections further or replace any damaged parts as needed.
  11. Final Adjustments:
    • Make any final adjustments to the faucet’s handle and other components to ensure proper function and a snug fit.

If you’ve followed these steps and your kitchen faucet still won’t turn off or you’re uncomfortable with faucet repair, consider contacting a professional plumber to assess and fix the issue. A professional can provide expertise and ensure that the repair is done correctly, preventing further damage and water waste.
