The Challenge
Water Could Be Heard Without A Visible Source
The customer could hear the sound of escaping water between the kitchen and utility room. Their plumber had already attended because of the noise, but the submission did not record what had been tested or concluded. With no exact source confirmed, the mains water pipe needed a structured investigation before the defect could be located.
- ✓ The customer could hear water escaping
- ✓ The sound appeared to come from between the kitchen and utility room
- ✓ The exact source was not visible
- ✓ A concealed mains water pipe leak needed to be investigated
Investigation
Investigation Evidence
Selected photos and videos from the investigation sequence showing the evidence-led approach used on site.
Investigation
Combining Pipework Tests With Focused Inspection
Pressure testing, acoustic detection, tracer gas and endoscopic camera inspection were used as part of the investigation. The sound justified checking the pressurised mains pipework, while the combined methods allowed the concealed area to be assessed without relying on one test alone. The engineer's record does not attribute the final location to a single method, so the evidence is presented as the result of the structured investigation as a whole.
Pressure Testing
The reported sound suggested that water could be escaping from pressurised pipework even though the source was not visible.
Pressure testing formed part of the mains water investigation between the kitchen and utility room.
The test contributed to the combined pipework evidence used to continue investigating the concealed mains route.
MethodAcoustic Detection
The suspected leak could be heard but its exact position still needed to be investigated within a concealed area.
Acoustic detection was recorded among the methods used during the investigation.
The record does not attribute the final location to acoustic detection alone, so it is treated as part of the combined evidence.
MethodTracer Gas Investigation
Tracer gas was selected as one of the recorded methods for assessing the concealed mains pipework.
Tracer gas testing formed part of the structured investigation between the kitchen and utility room.
No individual tracer gas result was recorded, so this method is not presented as standalone confirmation of the defect.
MethodEndoscopic Camera Inspection
A compact camera could provide a closer visual view within a difficult-to-access area as the investigation progressed.
Endoscopic camera inspection was completed and the supplied photograph records the camera view used on site.
The visual inspection supported assessment of the concealed area without claiming that the camera independently located the defect.
Findings
Small Pinhole Leak Found On The Kitchen Mains Pipe
The investigation identified a small pinhole leak on the mains water pipe in the kitchen. This finding explained why the customer could hear water escaping even though the precise source had not been visible at the outset. Specialist investigation was required to move from an audible symptom to a confirmed defect within the kitchen pipework.
- A small pinhole leak was discovered
- The defect was on the kitchen mains water pipe
- The confirmed leak explained the sound reported by the customer
- The source was established through the combined investigation
Outcome
Pinhole Leak Repaired And Escaping-Water Sound Stopped
- ✓ Leak Located
- ✓ Pinhole Defect
- ✓ Repair Completed
- ✓ Sound Stopped
The pinhole leak was repaired successfully. After the repair, the sound of escaping water stopped, confirming that the identified defect had accounted for the symptom reported at the start of the investigation.
Investigation Insights
What This Investigation Shows
- ✓The sound of escaping water can justify investigation when the exact source is not visible.
- ✓An audible symptom may indicate the general area of concern without revealing the precise pipe defect.
- ✓Several investigation methods can contribute evidence without one method being credited as the sole means of location.
- ✓In this investigation, the sound stopped after the confirmed pinhole leak was repaired.
