What this method contributes
Where appropriate, a suitable tracing dye or controlled water-path check can help investigate the link between a fitting and an affected area. The engineer considers the materials and risk of staining before testing, and records exactly what the observation demonstrates.
Where it can be useful
- Some bathroom water paths
- Use-dependent leaks
- Accessible fitting-related investigations
This is not a substitute for a full roof or drainage survey. It is used only where the conditions and materials are 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.
