A property in SO16 developed water ingress in two separate areas — underneath the bathroom basin and in the kitchen. Two leaks found and repaired; bathroom basin and kitchen wall pipe.

Found

leaking water trough fitting with waterlogged ground before leak detection works

engineer surveying open farm field with water troughs during leak detection

Private Water Supply Leak Didcot

Private Water Supply Leak / Didcot

With livestock water troughs, stable supplies, and garden tap pipework all drawing from the same system, isolating the cause required a methodical approach. Stop valve leak repaired; garden tap supply isolated; meter referral recommended.

Found

tracer gas manifold and compressor laid out beside radiator during leak detection

acoustic listening device on tiled floor of garage bathroom during leak detection survey

Central Heating Leak Bromley

Central Heating Leak / Bromley

The heating system at a property in CR0 had been completely off for around one week. Leak found on buried heating pipe, repaired under kitchen worktop.

Found

Hot Water Cylinder Overflow Leak Haywards Heath

Hot Water Cylinder Overflow Leak / Haywards Heath

A property in Haywards Heath presented with a damaged ceiling in the kitchen, showing visible watermarks that suggested water had been leaking from above. Leak found in ceiling void, overflow pipe replaced.

Found

boiler pressure gauge reading zero bar at initial inspection before leak detection works

Found

hallway carpet lifted to reveal damp concrete floor during leak detection

damp meter reading 999 on saturated hallway concrete floor during leak detection

Central Heating Leak Amesbury

Central Heating Leak / Amesbury

The absence of visible water made this a difficult problem to diagnose without specialist equipment. Leak found on copper tee junction beneath hallway floor, repaired.

Found

Damp wet patch on stone-effect floor tiles indicating a central heating leak at a property in BA3

Pressure testing gauges and hoses connected to valves on a tiled floor during a central heating leak detection survey at a property in BA3

Central Heating Leak Bath

Central Heating Leak / Bath

With nothing to see and no obvious starting point, this was a case for central heating leak detection using specialist equipment. Leak found beneath ensuite bathroom tiles, pipe replaced.

Found

spinning water meter dial checked during leak detection investigation

acoustic listening device and gas detector resting against brick wall during leak detection

Underground Water Mains Leak Brandon

Underground Water Mains Leak / Brandon

The occupants of a property in CV3 noticed a steady drop in water pressure alongside an unexplained rise in their water bill. Underground mains leak found in rear alleyway, excavated and repaired.

Frank (Ferenc Gulyas) from ADI - top professional

Frank on 1st job day found where is the leak, and also did the internal (inhouse) pipe replacement. Although re 2-nd day job was forgotten to book by ADI (not by Frank), after my call to ADI it was quicky resolved. Based on that Ferenc Gulyas (and Krzysztof Kobylinski) did an excellent job on a 2nd day: all was done in very high professional way, top quality, and after the job was finished making tidy all the access points. Great work, happy customer.

Great , great , great …..

Leak detected within 15 mins. Repair carried out.All completed within 3 hours. Mark , Krzysztof and Larry were extremely professional. To access the leak several bricks needed to be removed from blocked paved drive. After fixing the leak these were returned to their original position so well you wouldn’t know they had been removed. Great job and you can really trust these guys to rescue you should you have a leak. From initial enquiry to receiving the report after the fix was very impressed!

About Krzysztof

Krzysztof came into leak detection through a background in plumbing, heating, and water mains replacement, which means he understands how systems are built before he starts working out where they are failing. On site, he draws on acoustic listening equipment, tracer gas, thermal imaging, and leak correlation depending on what the situation calls for. He covers a broad patch across southern England and the Midlands. Away from work, he is a football fan with a taste for steak, seafood, and traditional Polish cooking.

Frequently asked questions about Krzysztof

What does Krzysztof specialise in?

Krzysztof specialises in central heating leak detection, water mains leak detection, underfloor heating leak detection, bathroom leak detection, drain leak investigation, and underground leak detection. He is particularly known for plumbing and heating work and water mains jobs, including full mains replacement where the pipe has failed beneath a driveway or garden.

How does Krzysztof detect hidden leaks?

He starts with acoustic listening equipment, which detects the sound of escaping water through floors, walls, or ground. Thermal imaging cameras are used where moisture movement is affecting surface temperatures behind tiles or beneath screed. Tracer gas and leak correlation equipment are brought in for buried or pressurised pipe runs where acoustic methods alone are not sufficient, and a borescope camera allows direct visual inspection inside cavities.

What experience and qualifications does Krzysztof have?

Krzysztof has 16 years in leak detection, 16 years in water main replacement, 16 years in internal and external plumbing, and three years as a Senior Water Mains Leak Detection Engineer at ADI. He holds a CSCS Card, Cat and Genny certification, and a digger licence, which covers him for the excavation work that sometimes follows a detection.

What types of properties does Krzysztof work on?

Krzysztof works on residential and commercial properties across southern England and the Midlands. Jobs range from internal plumbing and heating leaks in flats and houses through to underground water mains investigations on larger properties, including cases where the supply pipe runs beneath a driveway, patio, or garden and physical excavation is required after detection.

When should you call Krzysztof for leak detection?

If you have an unexplained rise on your water bill, damp patches appearing on walls, floors, or ceilings, or a central heating system losing pressure without an obvious cause, those are the situations that warrant a professional investigation. Call ADI Leak Detection on 0800 731 3843 to book an investigation and ADI will aim to assign Krzysztof where he is available in your area.

How Krzysztof finds your leak

Krzysztof 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.
