Sink Drain will not shut

    1. Remove drain stopper assembly and inspect rubber gasket for wear or damage. Replace if deteriorated.
    2. Clean stopper seat and ensure no debris is obstructing a tight seal. Scrub with brush or pipe cleaner.
    3. Check drain flange screws are tightened fully. Tighten or replace stripped screws.
    4. Take apart pivot rod assembly and clean internal parts of any built-up gunk or mineral deposits.
    5. Make sure pivot rod can move freely without friction. Lubricate joints with silicone spray if sticky.
    6. Look for cracks or stripped threads on clevis, tailpiece, or pop-up plug rod. Replace parts as needed.
    7. Reassemble drain mechanism ensuring spring and retaining nut are reinstalled correctly.
    8. Verify pop-up assembly alignment allows unobstructed vertical motion. Adjust as needed.
    9. If still not sealing properly, remove stopper and wrap plumber’s tape around flange threads for tighter fit.
    10. Consider replacing entire drain plug assembly if worn parts cannot be repaired.
