Movement at a correctly identified meter while the internal stop tap is shut can point towards flow on the supply between those points, but only if the valve genuinely isolates the property and no shared branch remains active. Leak detection in Aylesbury needs an accountable test, not a hurried glance into an uncertain chamber.
Confirm the meter and the isolation point
Use supplier records to identify the meter and photograph its serial where safely visible. Locate the internal stop tap and verify that ordinary cold flow stops, following water-company guidance. Do not force a stiff valve or operate an external stop tap without permission.
List outbuildings, outside taps and shared supplies that may branch before the internal valve. Their use can move the meter even though taps inside the house are off.
Record a clean interval
Photograph the full display at start and finish with exact times. Tell occupants not to use water and record any unexpected use. Avoid lifting a cover in traffic, reaching into a flooded chamber or leaving the building without essential water for longer than needed.
A changed display supports a supply-side question; it does not show the leak position. A stationary meter during one short interval may also miss intermittent use, so describe the test duration and limits.
Take the evidence to the responsible party
Thames Water explains the distinction between company pipework and the private supply. Provide the meter check, property boundary and any surface signs when requesting leak detection in Aylesbury. Clarify responsibility before agreeing excavation.
Keep people away from sinking paving, strong flow or a waterlogged chamber. Report public-road leakage to the water company. A private specialist may trace the route and combine isolation with suitable location methods.
Verify more than the repair location
After repair, repeat the same meter observation under comparable conditions and confirm normal internal flow when the stop tap is reopened. Record the actual pipe route revealed during access.
Do not judge success only because surface water stops; ground may drain slowly, and an intermittent leak can pause. Matching pre- and post-repair meter evidence gives the handover a clearer endpoint.
Keep the test understandable to others
Write the valve position, start reading, finish reading and elapsed time in one table. Add who observed it and whether any water use occurred. Avoid cropping photographs so tightly that the meter identity disappears.
If the stop tap does not fully isolate the kitchen tap, record that failure rather than continuing the test. The result is not valid for locating supply-side flow until the isolation boundary is understood and safely corrected.
