A digital icon or small dial can move briefly even when the main digits appear unchanged. That moment is worth recording, but it does not by itself prove continuous leakage or reveal where water went. Leak detection in Thatcham needs a defined interval, the correct meter and a complete list of automatic water users.
Identify what the display is showing
Photograph the meter serial and the complete display before interpreting a flashing symbol or rotating indicator. Some parts of a display show instantaneous flow while the numbered register accumulates total use. Use the supplier or meter instructions for that model; do not guess that every icon represents the same volume.
If several meters share a chamber, confirm which one serves the property. Never lift a heavy cover, enter traffic or touch seals and fittings. A sharp photograph taken from a safe position is preferable to leaning into a chamber to watch a small indicator.
Choose an honest no-use interval
Agree a short period when occupants will not use taps, toilets or appliances. List softeners, storage cisterns, irrigation, heating top-up arrangements and plumbed refrigerators that may operate automatically. A pulse caused by intended demand is still genuine meter movement, but it answers a different question from escaped water.
Capture the total reading at both ends with exact clock times. Note any indicator activity between them, but base the comparison on what the meter instructions say can be read reliably. If somebody uses water, label the interval inconclusive instead of editing that event out of the record.
Keep a pulse separate from a location claim
Movement establishes flow through the identified meter during that moment. It cannot distinguish a toilet refill from an underground supply leak, and it cannot show where a concealed escape sits. Shared supplies or branches before the internal stop tap make the boundary even more important.
Give the visitor the serial, photographs, start and finish readings and list of possible automatic users. If isolation is considered, only a familiar accessible valve should be handled, without force. Street controls and communal valves should be left to the responsible organisation or competent professional.
Verify the original meter question
After a confirmed fitting or pipe repair, repeat an equivalent interval with the same scheduled devices. Compare both the total register and the earlier indicator behaviour. One quiet check is useful evidence, not a guarantee about intermittent use outside the observation window.
Keep the meter evidence with the exposed defect, repair detail and post-work result. If unexplained movement remains, investigate the remaining branches rather than assuming the first repaired issue accounted for every pulse. Active flooding, unsafe ground or water near electrics requires urgent action instead of a prolonged meter test.
