The aim is to help you complete one clear task, recognize what needs verification, and avoid the most common mistakes. Work through the checks in order, then use the real-world example to apply them to your situation.

This guide is designed as a practical decision checklist. Use the relevant official guidance alongside the steps, especially when rules depend on your country, device or individual circumstances.

1. Look for indirect signs

Check for unusual moisture, peeling paint, musty odour, soft flooring and changes in the water bill. Photograph suspicious areas and note when they appear. Water can travel along materials, so the visible wet spot may not be the source.

2. Use a basic meter check

When safe and practical, stop all intentional water use and observe the meter indicator according to the utility instructions. If the meter changes while every tap is off, investigate hidden use or a leak. Do not manipulate sealed utility equipment.

3. Check accessible fittings

Inspect toilet mechanisms, sink connectors and visible pipe joints without disturbing pressurised parts. A toilet dye test can reveal continuous leakage into the bowl. If water is near electrical fittings, avoid contact and call appropriate qualified help.

4. Escalate before mould grows

Shut off the relevant valve if you know how and it is safe, then contact the owner or qualified plumber. Dry affected areas promptly and keep records for an insurance claim or landlord notice where relevant.

Verify the source before acting
