How to unclog a toilet

Start with a flange plunger. If you don’t have one, try the towel-and-bucket method below — then get a plunger for next time.

Stop if Water is near the rim and rising, or waste is overflowing onto the floor. Turn off the toilet’s water valve (usually behind the bowl, near the floor), soak up water, and call a plumber if a few careful plunges don’t help.

With a plunger

  1. Protect the floor Put down towels. Put on gloves if you have them. If the bowl is near overflowing, wait for the level to drop a bit, or scoop water into a bucket until you can plunge safely.
  2. Use the right plunger A flange (toilet) plunger has a soft rubber ring that seals inside the drain. A flat cup sink plunger works poorly on toilets — get a flange one if you can.
  3. Make a seal Lower the plunger at an angle so it fills with water (not air). Cover the drain opening completely. There should be enough water in the bowl to cover the plunger cup.
  4. Plunge firmly Push and pull with steady force — 10 to 15 strokes. Keep the seal. Don’t yank so hard that you splash everywhere. The up-stroke matters as much as the push.
  5. Test the flush Lift the plunger. If the water drops quickly, flush once. If it still rises slowly, plunge another round. Repeat up to 3 rounds.
Tip A little dish soap in the bowl can help the plunger slide and loosen soft clogs. Wait 5–10 minutes after adding soap, then plunge.

  1. Don’t keep flushing Extra flushes make overflows worse. Turn the shutoff valve clockwise if the bowl is rising.
  2. Hot (not boiling) water + dish soap Squirt a generous amount of dish soap into the bowl. Carefully pour a bucket of hot tap water from waist height into the bowl. Boiling water can crack porcelain — use hot from the tap, not a rolling boil.
  3. Wait, then try Wait 10–15 minutes. If the level drops, try one careful flush. If not, scoop some water out and try again, or move to a tool.
  4. Use a plastic drain snake if you have one Feed it into the drain gently until you feel resistance, then twist and pull. Don’t force a metal hanger deep into the trap — you can scratch porcelain or break the trap.
Safety Skip chemical toilet “bombs” and don’t pour drain cleaner into a toilet that’s already full — it can splash back and won’t clear a solid clog well.
