Signs Your Playa Blanca Villa Has an Underground Leak

There are many benefits to owning a villa in the south of Lanzarote because it will get some of the best weather on the island, but it's not always great news for your plumbing system. Because many villas in Playa Blanca are built on porous volcanic substrate, underground leaks often go unnoticed for months. Water does not always rise to the surface; it simply disappears into the ground. What is left is a humongous water bill.

As Leakbusters Lanzarote, the leading specialists for leak detection in Playa Blanca, we have identified the five most common warning signs that your villa may have a hidden pipe failure.

1. Unexpected High Water Bills

The first sign of a leak is usually financial. If your Canal Gestión bill has suddenly doubled without a change in your habits, you likely have a silent leak. In Playa Blanca's luxury villas, even a small pinhole in a main supply pipe can waste thousands of litres a day.

Understanding the causes of high water bills in Lanzarote is the first step toward taking control of your costs.

2. Damp Picón or Garden Patches

Lanzarote gardens use volcanic gravel (picón) to retain moisture, but if a patch of your garden remains dark or muddy long after the morning watering, it's a red flag. Constant moisture in a specific area usually indicates a pipe fracture beneath the surface.

What to Look For:

Darkened picón patches that stay wet when surrounding areas are dry

Unexpected plant growth or greener vegetation in one specific zone

Muddy spots that never fully dry out, even in Playa Blanca's intense sunshine

Puddles forming without any recent rainfall or irrigation

3. Sinking Terrace Tiles or Paving

Underground leaks eventually wash away the sand and substrate beneath your terrace. If you notice tiles around your pool or patio beginning to dip, crack, or feel hollow when walked upon, water is likely eroding the ground underneath.

This is particularly common in Playa Blanca villas with pool surrounds and elevated terraces. The constant flow of water beneath the surface gradually undermines the foundations, and by the time tiles start moving, significant erosion may have already occurred.

4. Water Meter Spinning Constantly

This is the most definitive check. If you turn off all taps and your water meter is still spinning, water is escaping somewhere between the meter and your house.

How to Perform the Meter Test:

Turn off every tap and water-using appliance in the villa

Locate your water meter — usually in a ground-level box near the road

Note the exact reading , including all decimal places

Wait 30 minutes without using any water

Check again — if the numbers have changed, you have a confirmed leak

This simple test costs nothing but provides conclusive evidence of water loss in your system.

5. Cracks in Perimeter Walls

When water leaks underground, the soil can expand or settle unevenly. This movement often causes vertical or diagonal cracks in your villa's perimeter walls or the muro surrounding your property.

While cracks can have other causes (settling, thermal expansion), new cracks appearing alongside any of the other signs listed here strongly suggest water-related ground movement.

What to Do Next

If you've identified one or more of these warning signs, here are your immediate next steps:

The Meter Test

Turn off your stopcock and check if the meter stops. If it continues running with the stopcock closed, the leak is between the meter and your stopcock — typically in the underground supply pipe.

Check the Aljibe

Ensure your backup water tank isn't constantly overflowing or refilling. A faulty float valve in the aljibe can cause continuous mains water consumption without you realising.

Professional Survey

If you can't see the leak, you need technology to find it. DIY methods rarely work on Lanzarote's volcanic terrain because water behaves unpredictably in porous rock.

How Leakbusters Finds Your Leak

Leakbusters provides expert leak detection and repair in Playa Blanca, using acoustic sensors and tracer gas to pinpoint the exact location of the break. This prevents the need for trial-and-error digging, saving you time and money.

Our Detection Process:

Acoustic geophones amplify the sound of water escaping through pipes, even deep underground

Tracer gas is introduced into the system and detected at the surface where it escapes through the break
