Tools Needed:

  • Adjustable wrench or slip-joint pliers

  • Needle-nose pliers

  • Small brush or old toothbrush

  • Paper towels or rags

  • Flashlight

Materials / Parts:

  • Bucket or small bowl

  • Mild bathroom cleaner

  • White vinegar (for mineral buildup)

  • Silicone-safe plumber’s grease (optional)

  • Replacement clip or spring (optional, if damaged)

Safety Warnings:

  • Place a bucket under the sink before loosening parts.

  • Do not overtighten plastic nuts on the drain assembly.

  • Avoid harsh chemical drain cleaners; they can splash.

Test & Verify:

  • Water drains quickly without pooling.

  • Stopper seals the sink when closed and lifts smoothly.

  • No drips at the pivot-rod nut or other drain joints after 2–3 minutes.

Cleanup & Disposal:

  • Toss hair/debris and rags; wipe the sink and vanity.

  • Rinse tools; leave the bucket dry under the sink.

Pre-Checks:

  • Confirm the sink uses a lift-rod pop-up (rod behind the faucet that raises/lowers the stopper).

  • Check under the sink for the horizontal pivot rod and retaining nut at the back of the drain.

  • Clear items from the vanity; set a bucket beneath the drain.

Step-By-Step Instructions:

  1. Raise the stopper with the lift rod, then pull the rod out to the neutral position.

  2. Under the sink, locate the small horizontal pivot rod entering the back of the drain. Place a bucket below it.

  3. Loosen the pivot-rod retaining nut by hand or with pliers and pull the rod straight out.

  4. From above, lift the stopper straight out of the drain. Note its orientation and whether it has a hole for the rod.

  5. Clean the stopper stem and cap: wipe hair and gunk; scrub with a brush and a little vinegar if there’s mineral buildup.

  6. Use needle-nose pliers to pull hair and debris from the drain throat. Wipe the seat clean.

  7. Rinse the parts. Lightly grease the stopper’s moving surfaces (optional).

  8. Reinsert the stopper into the drain, aligning the hole in the stopper stem toward the back where the rod goes.

  9. Slide the pivot rod back into the drain so its ball captures the stopper stem; hand-tighten the retaining nut, then snug gently—do not overtighten.

  10. Connect the pivot rod to the lift rod with the spring clip; test the motion up and down.

  11. Adjust the linkage holes to get a full seal when down and full lift when up.

  12. Run water and confirm fast drainage with the stopper up and a good seal when down.

When to Stop & Call a Pro:

  • Retaining nut or drain body is cracked and leaking.

  • Pivot rod won’t engage the stopper stem or repeatedly pops out.

  • Drain remains slow after cleaning (possible clog past the trap).

Common Mistakes:

  • Reinstalling the stopper without aligning the rod hole to the back.

  • Overtightening the plastic retaining nut and deforming the seal.

  • Skipping linkage adjustment so the stopper won’t seal or won’t rise fully.No permit is typically required for stopper cleaning or adjustment. Check local guidance if unsure.

Troubleshooting:

Q: Stopper won’t come out.
A: The pivot rod may still be engaged—loosen and remove the rod from the back of the drain first.

Q: It still drains slowly.
A: Remove and clean the P-trap or use a small hand auger; hair may be deeper in the trap.

Q: The stopper won’t seal after reassembly.
A: Move the clevis (lift-rod) clip to a lower hole for more travel, and ensure the pivot rod is inserted through the stopper stem hole.

Q: Drip at the pivot-rod nut.
A: Snug the nut slightly; if it persists, replace the small gasket/ball assembly on the rod.
