The Flow Detect notebook
What does a moving water meter mean?
Put an unexpected reading in the context of the supply it measures.
Check what the meter serves
A meter may supply more than the taps you can see. Appliances, stored-water systems and shared connections can affect the reading. A change does not automatically prove a buried private leak.
Useful information to share
Existing readings, the bill and supplier correspondence help describe the concern. Include any known shared supply arrangement and accessible valve positions.
How the investigation progresses
Suitable authorised checks can help separate normal demand, internal fittings and the incoming pipe. Tracing follows a useful system boundary rather than the bill alone.
Put the information into context
This guide explains common investigation principles. Your property, the available access and the actual test findings determine the right next step. It is not a diagnosis of an unseen system.
