The Flow Detect notebook
An unexpectedly high water bill
Distinguish a billing concern from a confirmed leak diagnosis.
Start with the evidence available
Actual readings and changes in household use provide context. A large bill does not by itself identify a failed pipe.
Consider hidden demand
Running fittings, appliances and shared supplies may contribute. The relevant checks depend on what the meter actually serves.
Keep the two questions clear
The supplier handles billing queries. A plumbing investigation establishes whether the agreed private system shows evidence of an escape and what work is 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.
