Underground Pool Leak in Surrey: How We Mark It Out, Step-by-Step

If you have a swimming pool in Surrey and notice unexplained water loss, higher water bills, or damp spots forming near your deck, you could be dealing with an underground pool leak. These leaks aren’t always easy to see, but they can cause significant water damage if ignored.

At BlackTie Pools, we specialize in underground pool leak detection and repair services for residential, commercial, and pool and spa systems across Surrey, Langley, White Rock, and the Greater Vancouver area. Using advanced Leaktronics leak detection technology, we can locate leaks with precision—without tearing up your yard unnecessarily.

This blog explains how we find and mark out underground pool leaks step-by-step, why it matters to address them quickly, and how our team of pool experts helps you keep your pool safe, functional, and efficient.

Why Leak Detection Is So Important for Your Surrey Pool

A hidden underground leak can be more dangerous than a visible crack because you don’t see the damage as it happens. Water escaping underground erodes soil, weakens patios, and can even damage nearby structures.

In Surrey’s varied climate—with heavy rains in winter and higher temperatures in summer—your pool system works hard year-round. Whether you have a vinyl pool, fiberglass, or another in-ground pool type, plumbing leak detection plays a critical role in preventing significant water loss and costly structural issues.

Common Signs Your Pool Is Leaking Underground

Underground leaks don’t always gush; sometimes they release water slowly, making them difficult to detect without professional services. Warning signs include:

• noticeable water pooling in certain areas of the yard
• lowered water level in your swimming pool despite no splash-out
• the sound of water escaping underground
• increased water bills without another explanation
• difficulty keeping pool chemicals balanced

If your pool is leaking, the sooner you call in expert leak detection, the less damage you’ll face later.

How We Use Advanced Leak Detection and Repair Services

At BlackTie Pools, we use advanced leak detection tools from Leaktronics to locate leaks without unnecessary damage to your property. These non-invasive detection methods include:

• Acoustic listening to hear the sound of water escaping from underground pipes
• Pressure testing to identify drops in the plumbing system
• Tracer dyes to pinpoint surface cracks or vinyl liner issues
• Specialized cameras to view hard-to-reach areas

This technology lets us locate the leak with accuracy so we can provide the right repair solutions and avoid unnecessary digging.

Step One: Pool Inspection and Identifying Leaks

Our underground leak detection process starts with a thorough inspection of the pool and surrounding systems. We test the pool pump, pool plumbing, and pool equipment to determine whether the leak you are dealing with is structural or in the pipes.

We also check the pool bottom, pool liner, and fittings for obvious damage. If there are hidden leaks, our tools can find them with pinpoint accuracy.

Step Two: Pressure Testing the Plumbing System

If the leak is suspected in the underground plumbing system, we perform specialized plumbing leak detection using air or water pressure to isolate which line is causing the water loss. This allows us to narrow down the issue—whether it’s a burst pipe, cracked fitting, or failing connection in the underground water network.

Pressure testing also helps confirm if the problem is in the suction lines, water lines, or return lines.

Step Three: Locating the Leak with Precision

Once we’ve confirmed there’s a leak, the next step is to locate leaks with precision underground. Using Leaktronics’ leak detection technology, our technicians listen for the sound of water escaping and track the exact spot.

This means excavation is minimal, reducing disruption and cost for Surrey BC, Langley BC, Maple Ridge BC, Delta BC, and nearby customers we serve.

Step Four: Marking Out the Problem Area

When we detect an underground leak, we physically mark the location at the surface. This step ensures that when repair services begin, we know exactly where to focus.

Whether you have a vinyl liner, concrete shell, or fiberglass structure, marking the location means less guesswork and faster leak repairs.

Why Underground Pool Leaks Happen

Underground leaks happen for many reasons:

• shifting soil around your pool in wet and dry conditions
• freezing and thawing cycles causing cracks in underground pipes
• aging materials in pool plumbing
• high water pressure in the water system
• neglecting pool maintenance and water care

Knowing these causes is key to addressing water loss before it turns into a major water leakage problem.
