What usually causes it
- Too much toilet paper or hygiene products flushed at once
- Items that should never be flushed — wipes, cotton buds, nappies
- A partial blockage further down the waste pipe
- An issue with the wider drain system
Why we do not recommend the popular online fixes
| Common online advice | Why it falls short |
|---|---|
| “Pour boiling water and washing up liquid down it” | Can crack ceramic if the bowl is already full, and rarely clears anything beyond the bowl itself. |
| “Keep flushing to force it through” | Risks overflowing the bowl onto the floor, creating a hygiene hazard. |
Stop and call us if…
- The toilet is at risk of overflowing
- Plunging has not cleared it
- It is the only toilet in the property
- You notice gurgling from other drains at the same time, which can mean a wider blockage
What it costs to wait
An overflowing toilet can cause water damage and a serious hygiene hazard, and a blockage that is part of a wider drain issue will not resolve itself and tends to get worse.
