A pool or water feature that loses more than evaporation explains is leaking somewhere — through the shell, a fitting, or the plumbing that circulates the water. Finding which, without draining and demolishing, is a job for sound. AnyLeak.ca uses submerged sonar and ultrasonic listening together with line pressure testing to locate leaks in pools, spas, fountains and ponds across BC.

How we find pool and water-feature leaks

  • Submerged listening. A hydrophone detects the sound of water leaving the vessel at a crack, skimmer, light niche or fitting — often while the pool stays full.
  • Pressure testing the lines. Suction and return plumbing is isolated and pressure-tested to separate a plumbing leak from a structural one.
  • Dye and visual confirmation. Where useful, controlled checks confirm the exact point before any repair.

Structural vs plumbing leaks

Telling the two apart is the whole game. A shell or liner crack, a failed light niche or a leaking skimmer is a structural fix; a leak in the buried suction, return or backwash line is a plumbing fix that may sit under a deck or in the yard. Pinpointing it precisely means one targeted repair instead of lifting an entire deck. This connects to our broader pool leak detection service.

Residential, strata and commercial

We work on backyard pools and spas, shared strata and commercial amenity pools and hot tubs, hotel and recreation-centre water features, and decorative fountains and ponds. On shared amenities, a quiet undiagnosed leak can waste enormous volumes of heated, treated water.

What to expect

Our process identifies whether the loss is structural or plumbing and pinpoints the location, with a report that supports insurance claims where applicable.

Where we work

Pool and water-feature leak detection is available across Metro Vancouver, the Lower Mainland, the Fraser Valley, the Sunshine Coast, Vancouver Island and the Okanagan — see all service areas.

Frequently asked questions

Do you need to drain the pool? Usually not — submerged listening finds many leaks with the pool full, which is faster and more accurate.

My pool only loses water when the pump runs — what does that mean? That often points to a pressure-side plumbing leak, which pressure testing will confirm.

A Closer Look at This Service

The cost of finding a leak is small compared to the cost of the damage it causes. A month of undetected leaking can wet insulation, rot framing, wash soil, and attract mould in the time it takes to book an inspection.

The best detection work is done by people who have seen the region’s buildings and buried systems fail in every common way. That experience is what turns a set of readings into a confident, cross-verified answer.

A professional investigation does not end with a verbal summary. It ends with a written report, and that report is the point of the exercise: a document that carries the finding, the evidence, and the guidance to the repair.

How the Investigation Is Delivered

Every investigation follows the same disciplined sequence: consultation, survey, testing, cross-verification, marking, and documentation. The sequence is deliberate, and each step builds on the last.

  • Step 1: Consultation to understand the situation and the history
  • Step 2: Site survey and indicator mapping
  • Step 3: Testing of the suspected systems with matched methods
  • Step 4: Cross-verification of the finding
  • Step 5: Marking and documentation
  • Step 6: Written, dated report

The second most common mistake is repairing the symptom. Patching the drywall, repainting the ceiling, or sealing the visible crack does not stop the water; it hides it. The water finds the next weak point, and the pattern repeats.

What This Costs

Pricing for this service in British Columbia depends on the scope of the investigation: the systems to be tested, the size of the property, and whether the finding is confirmed with a second method. A fixed quote is provided before any work begins, so there are no surprises on the invoice.

Every property is different, which is why pricing follows the investigation plan rather than a menu. The free consultation defines the scope, and the fixed quote follows it. What you are quoted is what you pay.

Insurance and Documentation

The report also protects the policyholder. When the cause is documented at the time of the loss, there is no later dispute about what was found, when it was found, or what the condition was.

Insurance claims fail most often because of missing documentation. A dated, photographed, method-by-method report removes that failure point and gives the adjuster a professional document they can rely on.

What the Report Includes

Reports are dated and structured so that any licensed contractor can take the marked location and proceed directly to the repair. They are also accepted by insurers, engineers, property managers, and, when needed, in dispute processes.

When to Call

Call when a decision needs documentation: an insurance claim, a real estate transaction, a strata dispute, or a warranty process. Those decisions run on evidence, and the evidence has to exist before the deadline.

Call before the damage becomes visible if the meter is moving with everything off. That reading is the earliest and cheapest moment to act, and acting early is what makes the repair small.

How to Prepare the Property

Nothing else needs to be done. The investigation does not require demolition, preparation of the systems, or any work on your part beyond access. Showing up with the history is the whole preparation.

The best preparation is information: when the issue started, what changed around that time, what the weather did, and what has already been tried. That history is often more valuable than any instrument.

Common Questions

Is this service non-invasive?

Yes. Every method used works from the surface and leaves no marks. Nothing is cut, dug, or permanently marked during the investigation.

How accurate is the location?

With cross-verified methods, locations are typically within a metre or less, and slab locations within inches.

Is the report useful for insurance?

Yes. The report documents the cause, the extent, the methods used, and the readings, structured for claims and engineering review.

How long does an investigation take?

Most property-level investigations complete within a day, and the written report follows within one to two business days.

Do you repair leaks?

No. Detection and documentation are the service. The report guides the repair contractor to the exact location.

What does this cost?

The quote is fixed before work begins, based on the scope defined in the free consultation. What you are quoted is what you pay.
