A damp patch is not automatically a burst pipe. It can be a shower membrane, a roof, condensation, or stormwater against the wall. Describe where it is and when it appears.
What to record
| What you noticed | Useful detail |
|---|---|
| A stain that grows in rain | Which wall or ceiling, and whether gutters overflow nearby |
| Damp only after a shower | Which bathroom, and whether it dries between uses |
| The water meter turning | All taps off, and whether the meter still moves |
| A stain with no obvious water | The room, and any recent painting or building work |
A plumber can separate a supply leak, a waste leak and stormwater. Ask which one they are testing. Do not lift flooring or cut a wall before that conversation if you can avoid it.
