Usually the handle moves but the drain stays closed because the pivot rod or its clip isn’t actually lifting the stopper. Remove the stopper and verify the pivot rod actually lifts it. If the rod is disconnected, broken, or seized, the stopper won’t open even when the handle moves.
Why This Happens
The mechanical link between the handle and the stopper is a small pivot rod and a clevis/clip. If that link is loose, broken, or misaligned the handle will move but not transfer motion to the stopper.
Mineral buildup or corrosion can jam the rod or stopper so motion at the overflow doesn’t translate to the stopper.
Occasionally the pivot rod or clip fails completely (for example, a Stopper rod broken), or the horizontal rod has slipped out of its slot under the stopper.
Step-by-Step What to Do
1. Prepare and protect the area
Put a towel or small bucket under the P-trap to catch any water or parts.
Have pliers, a screwdriver, and a flashlight ready.
2. Operate and observe
Move the handle up and down while looking under the sink. Watch the pivot rod near the tailpiece for movement.
If the handle moves but the rod doesn’t, the connection above is loose or broken.
3. Remove the stopper and check the linkage
Lift or twist the stopper as appropriate to the type you have and pull it out. If it won’t come free, loosen the pivot rod retaining nut under the tailpiece and pull the pivot rod back so the stopper releases.
Remove the stopper and verify the pivot rod actually lifts it. With the stopper out, move the pivot rod to confirm it is meant to lift the stopper; you should see the stopper’s slot move with the pivot rod.
4. Inspect and repair common faults
Check the retaining clip that holds the pivot rod to the vertical lift strap. If the clip is missing or bent, replace it.
Look for corrosion, mineral crust, or a bent/broken rod. Clean mineral deposits with vinegar and a brush; replace any badly corroded or broken pieces.
Re-seat the pivot rod so it fits into the stopper’s slot, then tighten the retaining nut finger-tight and test operation before final tightening.
5. Reassemble and test
Put the stopper back in place, reattach the pivot rod and clip, wipe up water, and test the handle several times. If it opens and closes smoothly, you’re done.
Check under the sink for leaks after reassembly and tighten connections gently if you see drips.
What Not to Do
Do not assume the handle is the issue if the pivot rod isn’t lifting the stopper.
Do not force rusty parts; forcing can break plastic or metal components and make repair harder.
Do not use chemical drain cleaners to fix a mechanical pop-up problem; they won’t help and can damage finishes or your plumbing.
When to Call a Professional
Call a plumber if the pivot rod or clevis is broken in a way you can’t safely replace, if the tailpiece or drain is cracked, or if you spot a persistent leak you can’t stop.
If cleaning and simple part replacement don’t restore motion, or you find a Pop-up assembly leaking, a pro can replace the pop-up assembly and ensure a watertight seal.
Safety Notes
Turn off water at the shutoff only if you’ll be disconnecting more than just the pivot rod; for this job, the sink faucet doesn’t usually need to be shut off.
Wear gloves to protect hands from sharp metal and old grime. Use eye protection if scrubbing under the sink.
Do not use excessive force on plastic parts; they can snap and create more work or leaks.
Common Homeowner Questions
Why does the stopper move but not open? Often the pivot rod is disconnected, broken, or jammed and therefore not lifting the stopper.
Can I fix this myself? Yes, most people can remove the stopper, inspect the pivot rod and clip, and replace simple parts without a plumber.
How long will a repair take? Basic inspection and reassembly usually take 15–45 minutes; part replacement may add time depending on access and parts needed.
