Our swimming pool leak detection surveys in Lanzarote go beyond simply confirming that a leak is present. Unlike other companies that only identify which section is affected, Canary Detect pinpoints the exact position of the leak using multiple detection methods, so you know precisely what needs repairing before a single tile is lifted.

Is Your Swimming Pool Losing Water?

If your pool water level is dropping day after day, it may not always be down to evaporation. Lanzarote's climate does cause some natural water loss, but anything beyond 1 to 2mm per day typically points to a hidden leak somewhere in your pool structure or plumbing systems.

The simplest check is the bucket test: fill a bucket with pool water and leave it on a pool step. After 24 hours, compare the water level inside the bucket with the pool water level. If the pool drops more than the bucket, you almost certainly have a leak rather than evaporation. A water meter check is another useful step: turn off all pool equipment and monitor the meter. If it continues to move, water is escaping somewhere in the system.

Other signs to watch for include: a pool level that keeps falling even after topping up; unexpectedly high water bills; damp ground or sinkholes around the pool area; loose or lifting tiles; and pool equipment struggling to maintain prime. If you notice any of these warning signs, arranging professional pool leak detection promptly will prevent the leak problem from developing into costly structural damage.

Why Property Owners and Property Managers Choose Professional Pool Leak Detection

Trying to find a pool leak without specialist equipment rarely works. Without professional leak detection services, water leaks in swimming pools are extremely difficult to locate accurately because they are often hidden inside the shell structure, within underground pipework, or deep inside the pump housing.

Left undetected, even a slow hidden leak causes serious problems. Water escaping from a pool can undermine surrounding ground, cause structural damage and water damage to the pool shell and surrounding terrace, and lead to further damage to fittings, tiles, and pipework. On top of this, the ongoing water loss adds to already high water costs in Lanzarote, where water is desalinated and more expensive than in mainland Europe.

Property owners and property managers across Lanzarote contact Canary Detect regularly after weeks of topping up their pools without understanding why the water keeps disappearing. Professional pool leak detection resolves the issue properly, giving you a clear answer and the information needed to arrange repairs. It is also one of the most effective ways of preventing water damage to your property in the long term.

Common Locations of Hidden Pool Leaks

Swimming pool leaks can occur in several different places, and knowing where to look is an important part of efficient detection. The most common locations for hidden water leaks in Lanzarote swimming pools include:

Pool shell cracks: Hairline cracks in the concrete or render of the pool shell allow water to seep slowly into surrounding soil. These are often invisible to the naked eye but show clearly on acoustic and thermal imaging scans.

Light fitting seals: The rubber seals around underwater light fittings degrade over time, especially with UV exposure and chemical treatment. A failing light seal can lose significant volumes of water over a week without any obvious visible sign.

Return fittings and skimmers: The seals where return jets, skimmers, and main drain fittings penetrate the pool shell are under constant stress from water pressure and thermal expansion. They are one of the most common sources of pool leaks in Lanzarote.

Underground pool pipework: The pipes running between the pool and the pump house are buried underground and invisible from the surface. Leaks in these pressurised pipes are among the hardest to find without specialist equipment, and are one of the primary reasons professional pool leak detection is essential.

Pump and filter connections: Joints and connections within the pump housing can develop slow leaks that go unnoticed because they are enclosed within the equipment area. We test every connection as part of our standard survey.

The Canary Detect Pool Leak Detection Process

Our pool leak detection process is thorough and systematic, testing every component of your pool from the shell outward. Here is how the entire process works from start to finish:

Shell and structural testing: We start with acoustic testing around all fittings, the pool shell, and light fittings, listening carefully for the sound of water escaping through cracks or failing seals. Our acoustic sensors are sensitive enough to detect even the smallest leak signature.

Pool equipment and pump housing testing: The pump, filter, and all fittings in the pump housing are tested thoroughly. Pool equipment connections are a common source of hidden water leaks that is frequently overlooked, so we include this as a standard part of every survey.

Pressure testing of pipework: All sections of pressurised pipes are pressure tested to identify exactly which section is holding and which is not. This is a key step in the leak detection process because it isolates the affected area before we apply more targeted methods.

Electronic shell testing: Electronic testing of the pool shell identifies structural weaknesses and hidden leaks that acoustic testing alone might miss.

Once a leaking section has been identified, we use CCTV cameras for internal pipe inspection, internal pipe hydrophones, external geophones, vacuum leak location, and H2/N2 gas insertion and detection to pinpoint the exact leak location.

The Technology We Use to Accurately Locate Leaks

Canary Detect invests in the most advanced technology available. Using the right tool for each situation is what leads to accurate results every time. Our water leak detection and pool leak detection equipment includes:

Thermal imaging technology: Our thermal cameras detect tiny temperature differences caused by water escaping from pool structures. Thermal imaging is especially effective for locating hidden leaks in shell linings, light fittings, and where pipework runs close to the surface.

Acoustic sensors: Water escaping from pressurised pipes produces a distinct sound. Our high-sensitivity acoustic sensors detect this even when the leak is buried underground, allowing us to accurately locate leaks without digging exploratory trenches.

Tracer gas detection: For concealed pipework where acoustic and thermal imaging methods cannot reach, we use tracer gas technology. A safe nitrogen and hydrogen mix is introduced into the pressurised pipes, and the gas escapes at the exact leak point where it is detected by our surface instruments. Tracer gas is one of the most reliable methods available for finding hidden leaks deep in underground pool plumbing systems.

Dye testing: A dye test allows us to visualise the movement of water around fittings, returns, lights, and shell surfaces, making it straightforward to confirm exactly where water is entering or leaving the pool structure.

No Costly Excavation Work Without a Confirmed Target

One of the main reasons property owners and managers choose Canary Detect is our ability to find hidden leaks fast before any digging begins. Our approach means we never carry out costly excavation work or start breaking walls until we know the exact leak location.

This avoids unnecessary disruption to your property, keeps repair costs down, and gives the repair team a confirmed target rather than guesswork. For occupied villas and holiday properties in Lanzarote, minimising disruption is essential, and our detection and repair process is designed to deliver precisely that.

Where leaks need immediate attention, we advise you clearly. Where a leak is slow and can be monitored, we provide expert advice on timing so you can plan repairs at a convenient time.

What Does Pool Leak Detection Cost in Lanzarote?

We operate with transparent pricing. The leak detection cost for a swimming pool survey depends on the pool size and complexity of your plumbing systems, but you will always receive a clear quote before work begins.

If you are weighing up the detection cost against simply continuing to top up the pool, consider what water loss is actually costing you each week. For most pools with an active leak, the cost of a professional leak detection service is recovered within a few weeks of water saved, and that is before taking into account the cost of preventing structural damage and avoiding expensive repair solutions further down the line.

After the Survey: Repair Solutions and Insurance Claims

Every pool leak detection survey includes a detailed professional report documenting the survey method, leak locations found, and recommended repair solutions. This report is formatted to support insurance claims, which is frequently required for properties in Lanzarote.

The repair process is entirely your choice. You are free to use your own repair contractor to repair leaks once they have been located, or our plumbing services team can manage the complete detection and repair process from start to finish. Either way, you receive a clear, accurate survey that tells your repair team exactly where to work, saving time and avoiding unnecessary costs.
