Toilet repair help

A faulty flush, cistern, or running toilet?

This page covers toilet working parts: the flush control, cistern filling and water that continues to run. If waste water rises or drains slowly, see Blocked Toilet.

Describe the working part

Which toilet behaviour needs attention?

Flush control does not respond

Note whether a button, lever or sensor feels loose, sticks or produces no normal flush action.

Cistern does not refill normally

Listen for filling, note the cistern water level only where it can be viewed safely, and avoid forcing a control.

Water keeps moving

Record whether water continues into the pan, the cistern keeps filling or the sound stops after a while.

Flush fault or blockage?

The water level can help you choose.

If waste water rises, stays high or drains slowly, see Blocked Toilet. If the flush mechanism, refill or continuous running is the issue, this page is the best place to start.

Describe the toilet mechanism, not a guessed fault.

Add the control type, cistern sound and visible water movement so the repair enquiry stays distinct from drainage.
