Your water meter is a simple tool that reveals unnoticed consumption at home. The test doesn't locate a leak or identify its type, but it's a useful first indicator before requesting an inspection.
Before the test
Set up the conditions so the result is meaningful:
- Close all taps and internal valves
- Stop washing machines, water heaters and any water-using appliance
- Make sure the tank float valve isn't refilling during the test
- Tell household members not to use water during the test
Test steps
Note the meter reading precisely (or photograph it), wait one to two hours with no water use, then read it again. A changed reading means unnoticed consumption. Some meters have a small dial that spins with the slightest flow; watch it for two minutes with taps closed.
How to interpret the result
A changed reading may mean a pipe leak, a running toilet cistern, a tank float that won't shut, or an automatically running appliance. An unchanged reading doesn't rule out a drain leak that only occurs during use, or rainwater ingress. The test is an indicator, not a final diagnosis.
When to request a specialist inspection
If the reading changes across repeated tests, or comes with a higher bill or damp signs, it's best to request leak detection to pinpoint the source before any breaking or restoration work.

Frequently asked questions
How long should the meter test last?
One to two hours is usually enough. The longer the no-use period, the clearer the result; you can repeat the test at another time to confirm.
The meter moves with taps closed — is that a confirmed leak?
Not necessarily; it could be a running cistern, a tank float or an automatic appliance. The test indicates unnoticed consumption without identifying its source.
