Account for water use
Automatic appliances, storage systems and other users on a shared supply can affect a reading. A moving meter needs context before it is treated as evidence of a buried failure.
Keep useful observations
Record the reading and time alongside known consumption. Tell the investigator about accessible isolation points and any water-company notice.
Define the route
The position of the meter, the building entry and any branches helps frame the next check. Do not interfere with the meter or water-company apparatus.
