The Challenge
Heating System Losing Water Through A Hidden Leak
The property had symptoms consistent with a concealed central heating leak. A constantly running feed and expansion tank can indicate ongoing water loss from the heating circuit, especially where pipework is hidden beneath floors or within building fabric.
- ✓ Central heating system losing water
- ✓ Feed and expansion tank repeatedly running
- ✓ Potential concealed pipework leak
- ✓ Investigation required before wider access work

Investigation
Evidence-Led Heating Leak Investigation
The investigation combined thermal imaging, moisture meter checks, tracer gas testing and tracer gas sniffer work to narrow the likely leak position before repair work was planned.
Feed And Expansion Tank Symptom Review
A constantly filling feed and expansion tank can indicate ongoing water loss from the central heating circuit.
The property had symptoms consistent with a concealed central heating leak beneath floors or within building fabric.
This focused the investigation on hidden heating pipework rather than visible plumbing fixtures.
MethodCombined Heating Leak Detection
Multiple non-destructive methods were appropriate because the leak was concealed and needed narrowing before repair work.
Thermal imaging, moisture meter checks, tracer gas testing and tracer gas sniffer work were used.
The combined evidence helped confirm the leak location and support focused repair work.
Findings
Leak Location Confirmed Quickly
The combined investigation methods helped confirm the leak location without unnecessary disruption. Evidence from the survey supported a focused repair rather than wider exploratory access.
- Thermal imaging used to identify temperature anomalies
- Moisture meter readings used to assess affected areas
- Tracer gas used to test concealed pipework
- Leak position identified for targeted repair
Outcome
Leak Located And Repaired With Minimal Disruption
- ✓ Leak Located
- ✓ Non-Destructive Investigation
- ✓ Minimal Disruption
- ✓ Repair Completed
The leak was located quickly and the repair was completed with minimal disruption to the property. The investigation avoided broad exploratory access and helped focus repair work on the confirmed area.
Investigation Insights
