Low urgencyPlumbing

Running toilet

Check whether the fill valve or seal is sticking. Turn off the local water supply if overflow risk increases.

SAFETY FIRST

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.
COMMON CAUSES

What could be behind it

  • Worn seal, valve or fitting
  • Local pipe/joint issue
  • Supply or pressure problem

These are common possibilities, not a diagnosis of your specific home.

DIY BOUNDARY

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.
