Start with what you have noticed
A pressurised hot or cold pipe can lose water even when nobody is using a tap. Leaks may remain concealed inside walls, floors or boxed-in pipework. The investigation needs to establish the affected system before tracing its route.
Separate the supplies before tracing
Where practical, checks on accessible controls and pipework help identify the part of the system involved. The method then depends on the route, construction and useful access points. Pressure testing, acoustic listening, thermal observations or tracer gas can contribute to the evidence, with targeted access agreed when appropriate.
Signs that can prompt an investigation
- Unexplained damp near a supply route
- Persistent water loss inside the property
- A concealed pipe suspected after alterations
- Water appearing while fixtures are unused
