Blocked toilets: what to try and when to stop
The practical points
- 1
A WC plunger or a WC auger clears most local blockages within the trap and the first section of branch.
- 2
If other fittings gurgle or back up at the same time, the blockage is in the shared drain and needs different equipment.

Your questions answered
Should I keep flushing?
No, each flush adds volume with nowhere to go.
What causes repeat blockages?
Wipes, excess paper, or a branch with insufficient fall that never fully clears.
