1. Begin by shutting off the main water supply to stop the flow. 2. Open the leaking tap to drain any remaining water from the pipes. 3. Plug the sink or basin to avoid losing small parts during the repair. 4. Unscrew or pry off the cap to take off the tap handle. 5. Unscrew the tap bonnet or valve cover to reach the internal components. 6. Remove the washer, jumper valve, O-ring, or cartridge, and check for wear or damage. 7. Clean or replace any faulty parts to restore functionality. 8. Put the tap back together in reverse order, ensuring parts are securely positioned without overtightening. 9. Slowly turn the water supply back on and check for leaks and proper tap operation.
