Drains & clogs

Tub still drains slowly after plunging

If a bathtub is still slow after plunging, the clog is often deeper in the internal stopper linkage or trap, which a simple surface plunge can't always fully reach.

Symptoms

  • Plunging improved drainage slightly but didn't fully fix it
  • Water still takes a long time to clear
  • Gurgling continues even after plunging
  • Tub drained normally not long ago

Likely causes

  • CommonHair tangled in the internal stopper linkageTrip-lever and pop-up style stoppers have internal mechanisms that trap hair beyond the reach of a plunger.
  • CommonClog deeper in the trap below the tubA partial clog further down doesn't always clear with surface suction alone.
  • PossiblePlunger seal not effective due to the overflow openingAn uncovered overflow lets suction escape, weakening the plunge.
  • PossibleBuildup requiring mechanical removal rather than suctionSome hair masses are too dense for plunging to dislodge.

What to do

  1. Cover the overflow opening with a wet rag before plunging again to ensure a proper seal for suction.
  2. If it's a trip-lever style tub, remove the overflow plate and pull out the entire linkage assembly to clear hair caught inside it directly.
  3. For a lift-and-turn or push-pull stopper, remove the stopper itself and clear hair from around its base and post.
  4. Use a plastic zip-style drain tool down the drain opening to pull out additional hair.
  5. If accessible, feed a hand-crank drain snake through the overflow opening, which often provides a straighter path to the trap than the drain itself.
  6. Reassemble the stopper mechanism and run water to test improved drainage.
  7. If it's still slow after all of this, the clog may be beyond the trap and worth having a plumber address.

Tools and parts

  • Screwdriver
  • Plastic zip-style drain tool
  • Hand-crank drain snake

When to call a pro

Call a plumber if clearing the internal linkage and snaking through the overflow doesn't restore normal drainage.
