The Flow Detect notebook
When more than one property shares a supply
Define the system before instructing an investigation.
Identify connected users
Shared branches affect both the interpretation of readings and the practical effect of shutting a supply. Plans and local knowledge can help.
Agree access and authority
Someone needs to coordinate the properties, arrange permission and authorise work on the relevant parts of the system.
Confirm the quotation
A shared system may require a wider instruction than one residential repair. Its scope and price are agreed separately when appropriate.
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.
