Toilet Flushing Troubleshooting

Although a standard toilet features a fairly basic design, periodic toilet problems are inevitable. Fortunately, a flushing problem substantially narrows down the number of potential problems.

Most flushing problems can be resolved in less than 30 minutes.

Things You Will Need

  • Screwdriver or pliers
  • Replacement lift wire or chain (optional)
  • Plunger
  • Closet auger

Although a standard toilet features a fairly basic design, periodic toilet problems are inevitable.  Fortunately, a flushing problem substantially narrows down the number of potential problems.

If the toilet will not flush, the problem is probably a broken lift wire or a water supply valve that was inadvertently left off.  If the toilet flushes slowly or if it overflows, the problem is probably a clog within the toilet or within the structure’s main plumbing line.


Toilet Will Not Flush

  1. Rotate the water supply valve located against the wall and behind the toilet in a counterclockwise direction to ensure that the toilet is receiving a supply of water.
  2. Lift the lid off of the toilet’s tank to expose the lift wire. Some toilets are equipped with a chain rather than with a wire.
  3. Replace the lift wire or chain if it is broken. Each end of the wire is secured with a screw or clip. Remove the fastener with a screwdriver or with pliers to release the wire.

Toilet Overflows or Flushes Slowly

  1. Fill the toilet with a few inches of water if the bowl is empty.
  2. Plunge the toilet with a plunger to clear most toilet clogs.
  3. Insert a closet auger into the drain opening within the bottom of the bowl if the drain is still clogged. The auger features a flexible metal bar that will conform to the drain pipe. Push the auger into the drain opening to clear the drain passageways.
  4. Contact a professional plumber if the problem persists, as the problem is most likely not with the toilet.
