Unclog a toilet

Most toilet clogs clear with the right plunger used the right way. Use a flange plunger, the kind with a soft extension that seals into the drain opening, not the flat cup type meant for sinks.

  1. Stop the overflow. If the bowl is close to the rim, close the shut-off valve behind the toilet, or lift the tank lid and hold the flapper down.
  2. Seal and plunge. Get the plunger fully underwater over the opening, push gently to let the air out, then plunge firmly in and out.
  3. Use an auger if it won’t budge. A toilet auger (closet auger) has a guard that protects the porcelain and reaches the trap inside the toilet.

Don’t pour chemical drain cleaners into a clogged toilet. If you plunge and it comes back, or other drains gurgle or back up too, the clog is further down the line, and that’s a plumber’s job. Related: Toilet won’t flush and Fix a running toilet.
