Blocked sink
Try only simple low-risk clearing. Stop if chemicals were already used or water backs up elsewhere.
What to do first
- Check whether the issue is isolated or affects the whole home.
- Take photos and note any recent changes, work or weather.
- Stop DIY if the task involves regulated work, hidden services, height or a safety risk.
What could be behind it
- Local trap/outlet blockage
- Build-up deeper in the waste pipe
- External drainage restriction
These are common possibilities, not a diagnosis of your specific home.
When to stop doing it yourself
Stop if you are unsure of the cause, cannot isolate the system safely, need to open fixed electrical/gas equipment, work at height, disturb hidden building fabric, or the problem is getting worse.
