Toilet problem
Running, weak flush, blockage, or a toilet that won't stop filling.
Quick things to check first
- 1Check the flapper/valve inside the cistern for wear or misalignment.
- 2Check the fill valve and float height if it keeps running.
- 3Try a plunger for a blockage before anything else.
These are general pointers, not a full diagnosis. For guidance tailored to your exact problem, show us a photo and describe it.
When to call a professional instead
- The pan or cistern itself is cracked
- A blockage doesn't clear with a plunger
