Toilet not flushing properly: common reasons

A weak or incomplete flush can involve the cistern mechanism, water level, rim outlets or a developing blockage.

Likely causes

  • A faulty button or linkage, low cistern fill, worn flush valve or restricted pan can reduce the flush.

Safe checks you can make

  • Watch whether the cistern refills and whether the button feels different.
  • Do not repeatedly flush if the bowl level rises.

When to stop and get urgent help

  • Stop using it if waste threatens to overflow or other drains begin backing up.

How a plumber can help

  • A plumber can inspect the cistern and pan and determine whether drainage clearance is also needed.
