Water Pipe Leak Detection Lanzarote

Water pipe leak detection is the process of locating a leak within the pipework of a property without unnecessary demolition or excavation. Using a combination of pressure testing, CCTV inspection, tracer gas, acoustic sensors, and thermal imaging, we identify exactly which pipe is leaking and precisely where the fault is located.

Knowing the exact position before any repair work begins saves property owners in Lanzarote enormous time and money. Without accurate detection, contractors can spend days opening walls and floors looking for a leak that Canary Detect can pinpoint in hours.

Properties across Lanzarote use a variety of pipe materials, and each material has its own failure patterns and detection challenges.

Copper Pipes

Copper was the standard for quality installations across the island for decades. Copper pipes can develop leaks from galvanic corrosion near brass fittings, vibration fatigue at elbows and bends, or damage from the aggressive desalinated water supply used in Lanzarote. Thermal imaging is particularly effective at locating copper pipe leaks behind walls and beneath floors.

PVC and CPVC Pipes

PVC plastic pipes are widely used in modern Lanzarote installations. They typically fail at adhesive joints, especially where the original installation was rushed or used incorrect solvent. UV exposure on exterior sections also causes degradation over time. Pressure testing is the most reliable method for isolating faulty PVC joints.

Polyethylene (PE) Pipes

Polyethylene pipes are commonly used for underground supply connections running from the meter to the property. These pipes can be damaged by gardening tools, tree roots, or ground movement. Our tracer gas technology is ideal for locating buried PE pipe leaks without excavation.

Galvanised Iron Pipes

Galvanised iron pipework is found in older Lanzarote properties, particularly those built in the 1970s and 1980s. These pipes develop internal corrosion that gradually reduces flow before eventually perforating. CCTV internal inspection reveals the true condition of galvanised pipes and helps plan renovation before a leak causes serious damage.

The water supply across the Canary Islands is desalinated, which means it carries a higher mineral content than typical mainland European water. Over time, this hard water accelerates corrosion inside metal pipes, particularly older copper and galvanised iron installations. Joints weaken, pipe walls thin, and small cracks develop that allow water to escape slowly and silently for months before visible damage appears.

This makes water pipe leak detection particularly important in Lanzarote. The combination of aggressive water chemistry and often ageing pipework means leaks are common, and they tend to worsen quickly once they start.

Many homeowners and property managers do not realise they have a pipe leak until significant damage has already occurred. Watch for these signs:

Unexplained increases in your water bill, even a small pipe leak can waste thousands of litres per month. Damp patches appearing on walls or floors with no obvious cause. The sound of running water when all taps are off. A water meter that keeps moving when everything in the property is switched off. Low water pressure at taps and showers. Mould or mildew appearing in unusual places. Warm patches on a floor above a hot water pipe that is leaking.

If you notice any of these signs, the earlier you call Canary Detect for a pipe leak survey, the less damage will occur and the lower your eventual repair bill will be.

Pressure testing is the starting point for understanding the condition of any pipe system. Canary Detect uses several approaches:

Static pressure testing involves isolating sections of pipework and monitoring pressure over a set period to detect even the smallest active leaks. Differential testing compares actual consumption with expected flow to quantify the rate of water loss. Isolation testing identifies exactly which section or zone of the property's system is affected, allowing us to focus detection work precisely.

Pressure testing confirms a leak exists and helps us understand its severity before moving on to precise location methods.

Our push-rod CCTV cameras can enter pipes from 25mm diameter upwards, providing high-definition internal footage of the pipe's condition. CCTV inspection is particularly valuable for older pipes where internal corrosion or structural failure is suspected.

CCTV surveys provide direct visual confirmation of cracks, corrosion and scale deposits, precise location of faulty joints and pinhole leaks, overall condition assessment to support maintenance planning, and video documentation for insurance claims and repair quotes.

For galvanised iron and older copper installations, we often recommend a CCTV survey as part of any leak detection visit to assess the wider condition of the pipework, not just the current leak.

Where a pipe leak is underground or buried beneath concrete, tracer gas is the most precise location method available. We pressurise the pipe with a safe, non-toxic nitrogen and hydrogen gas mixture. The gas escapes wherever water is also escaping, rises through the ground, and is detected at the surface using a sensitive probe.

This technique can locate buried pipe leaks beneath terraces, driveways, gardens, and pool surrounds without any excavation. It works through virtually any ground surface and is unaffected by the depth of the pipe.

Acoustic sensors listen for the specific sound that pressurised water makes as it escapes through a crack or faulty joint. Different pipe materials transmit this sound differently, and our trained technicians know how to interpret the acoustic signatures of copper, plastic, and metal pipe leaks.

For longer pipe runs, acoustic correlators compare the sound signal from two points along the pipe to calculate the exact leak position mathematically, locating it to within centimetres.

Thermal imaging cameras detect the temperature changes caused by leaking water behind walls and beneath floors. Water from a leaking pipe cools the surrounding surfaces in characteristic patterns that are invisible to the naked eye but clearly visible to our thermal cameras.

This is particularly effective for leaking hot water pipes, underfloor heating systems, and any pipe running through a wall or ceiling where the temperature difference is large enough to show clearly on the thermal image.

Many serious pipe leaks in Lanzarote occur in the underground supply connection running from the street meter to the property. These buried pipes are often old, and ground movement or excavation damage causes them to fail silently, with water escaping into the ground for months before a homeowner notices.

For underground pipe leaks, Canary Detect uses electromagnetic locators to trace metallic pipes, ground-penetrating radar for non-metallic plastic pipes, tracer gas for precise leak location in buried pipework, and acoustic correlators for pipe position triangulation. Read our full guide on how to detect underground pipes in Lanzarote for a deeper look at each technology.

Every Canary Detect water pipe leak detection survey produces a full written report including the type of pipe affected, the exact leak location with photographs and coordinates, the probable cause of the failure, recommended repair options, and an assessment of the wider pipe system condition.

These reports are accepted by all major insurance companies operating in the Canary Islands for claims and repair authorisation. Once your leak is confirmed, our leak repair team can address it promptly. They are also useful when obtaining comparative quotes from repair contractors, as each contractor has a precise brief rather than having to make assumptions.
