Leak Detection Case Studies by Robert Gires
Recent leak investigations carried out by Robert Gires across central heating, water mains, underfloor heating and bathroom leak detection.
External Cold Water Mains Leak / Guisborough
The property in TS11 is a large semi-detached house where the water meter had been observed spinning continuously and very slowly, indicating a constant draw of water somewhere on the system. Leak found under kitchen floor, mains pipe repaired.
Central Heating Leak / Alton
The property in GU34 is a large detached house with a substantial heating and hot water setup: an oil boiler in the ground floor utility room serving 20 radiators and an underfloor heating circuit, plus two hot water cylinders on the first floor. Leaks found in kitchen and living room floor, pipework replaced.

About Robert
Robert came up through the plumbing and heating trade, spending 20 years on installation and fault-finding before moving into specialist leak detection. That grounding means he reads a property's pipework quickly — whether it's a domestic central heating circuit or a buried mains supply — before deciding how to approach the investigation. He covers a wide stretch of northern and central England, from Merseyside and Greater Manchester down through the Midlands. Away from work, Robert is an enthusiastic gardener and has a genuine interest in world foods and traditional cuisines.
Frequently asked questions about Robert
What does Robert specialise in?
Robert specialises in central heating leak detection, water mains leak detection, underfloor heating, bathroom leaks, drain leak investigation and underground pipework. He is particularly well known for central heating and water mains work, and his 10 years of powerflushing experience adds useful context when investigating faults in heating circuits.
How does Robert detect hidden leaks?
Robert uses acoustic listening equipment to hear water escaping through pipe walls beneath floors and ground surfaces. Where a leak is suspected behind a structure, thermal imaging identifies temperature variations caused by moisture without removing materials. Tracer gas is used on pressurised systems — a safe gas mixture is introduced into the pipework and detected at surface level to locate the exit point. Borescope cameras and moisture meters support the investigation where physical access is limited.
What experience and qualifications does Robert have?
Robert has 25 years in domestic and commercial plumbing, 20 years in plumbing and heating, 5 years in leak detection, 5 years in water mains leak detection, and 10 years in powerflushing. He holds an NVQ Level 2 in plumbing, heating and gas.
What types of properties does Robert work on?
Robert works across residential and commercial properties, covering everything from internal leaks on domestic heating systems through to buried mains supply pipes requiring full replacement. He is experienced with older and newer plumbing configurations, and his trade background means he can assess system condition accurately before the detection investigation begins.
When should you call Robert for leak detection?
If your water bill has risen without explanation, your boiler is losing pressure repeatedly, you can hear water running when everything is off, or damp patches are appearing on floors or walls, those are all signs worth investigating. Call ADI Leak Detection on 0800 731 3843 to book an investigation — ADI will aim to assign Robert where he is available in his coverage area.
How Robert finds your leak
Robert follows a consistent five-stage process on every visit. The approach is non-invasive and designed to isolate the fault before any disruption to your property.
- Initial assessment. Review symptoms with the customer, check visible evidence, and identify the most likely system involved.
- Selection of the right detection method. Pick the combination of thermal imaging, tracer gas, acoustic listening, or moisture mapping most likely to isolate the fault.
- Non-invasive testing. Run the chosen method across the candidate area — no excavation or destructive investigation until the leak is confirmed.
- Leak confirmation. Cross-verify the finding with a second method where possible, mark the exact location, and document the evidence.
- Reporting and next steps. Provide a written report, photographs, and recommended repair options.
