What this method contributes
An appropriate section of pipework is assessed, prepared and isolated before a controlled tracer test is used. A detector then checks relevant surfaces. Gas may take a route through voids before emerging, so the readings are interpreted with the construction and other findings.
Where it can be useful
- Quiet concealed leaks
- Pipework beneath solid floors
- Suitable isolated heating circuits
Surface readings can be displaced from the fault. Preparation, isolation and safe test conditions determine whether this method is suitable.
Why methods are considered together
Several observations can support a more useful decision than one isolated result. We consider the symptom history, accessible plumbing and system behaviour alongside specialist findings. The equipment is selected for the property and its conditions.
There is no need to select a test yourself before enquiring. Explain what you have noticed and share any previous findings. We can then agree an appropriate investigation.
The next decision is about access
The evidence informs where a concealed pipe may need to be reached. Suitable tracing can reduce speculative opening, but the plumbing repair still needs physical access. Restoring the surrounding finishes is a separate stage.
