Is Your Pool Losing Water or Not Holding Pressure?

Most clients do not search for “leak detection” straight away.

They search because something is wrong:

These are all signs of a deeper system fault.

The real issue is not just confirming a leak, it is understanding where it is and what caused it.

Why Pool Leaks Often Lead to Expensive Repairs

In many cases, the first step is a pressure test.

This tells you:

But it does not tell you where the problem is.

This is where things escalate quickly.

Typical outcome:

This can lead to:

Many clients either delay the work or live with the leak.

How We Diagnose Swimming Pool Leaks

We use a staged process to move from symptoms to clear evidence.

Tracer Dye Testing Around the Pool

This is a non-invasive starting point.

We use fluorescent dye to check:

  • Pool fittings
  • Lights
  • Liners
  • Tiles and grout

If the dye tracks toward an area, it indicates a leak in the pool structure.

If it does not track anywhere, the issue is likely in the pipework.

Pressure Testing Pool Pipework

This is the industry standard method.

We:

  • Isolate the pipe
  • Fill it with water
  • Pressurise to around 1 Bar (15 PSI)
  • Monitor with a gauge

Outcome:

Holds pressure = pipe likely sound

Drops pressure = confirms a leak

This proves the problem, but not the location.

Camera Inspection Inside Pool Pipes

We use a specialist swimming pool inspection camera designed for smaller pipe diameters.

This allows us to:

  • Inspect inside the pipe
  • Capture video evidence
  • Show the client what we see

Important to understand:

Not all leaks are visible

Many failures occur at joints or subtle defects

This is where most standard diagnostics stop.

Our USP – Vacuum Testing with Camera Inspection

This is where HydroTech Pools goes further.

We combine camera inspection with vacuum testing.

Instead of forcing water out, we:

This allows us to identify:

With the camera inside the pipe, we can often see where the failure is occurring.

Locating the Exact Area of Failure

Our camera includes a built-in 512hz transmitter.

Using a receiver above ground, we can:

This allows:

Watch how the vacuum system works:

Real Example – Avoiding a Full Pipe Replacement

A recent project involved:

  • A pool line failing a pressure test
  • Deep concrete pool construction
  • Previous tracer gas attempts with no result
  • Other contractors unable to access the pipe

Our process:

  • Inserted specialist camera successfully
  • No visible issue at first
  • Applied vacuum testing
  • Identified air entering at pipe fitting
  • Traced location using receiver
  • Excavated and repaired locally
  • Re-tested and confirmed pressure held

Result:

  • Problem solved with a targeted repair
  • Significant cost saving compared to full replacement

Common Causes of Pool Pipe Leaks

Most failures happen over time, not instantly.

Typical causes include:

These issues often affect joints and fittings below ground.

What Happens After the Leak Is Identified

Once located:

Only once it holds pressure is the area reinstated.

If it fails again, it may indicate another issue further along the line.

Other Leak Detection Methods Explained

Tracer Gas Detection

This method involves:

  • Injecting gas into the pipe
  • Detecting where it escapes above ground

Used by:

  • Water companies
  • Specialist contractors

Limitations:

  • Gas does not always rise directly above the fault
  • Ground conditions affect accuracy
  • Not always precise in pool environments

HydroTech Pools does not offer this service and instead focuses on methods better suited to swimming pool systems.

FAQs

How do I know if my pool has a leak?

Ongoing water loss, air in the system, and pressure drops are key indicators.

Yes, using specialist equipment designed for pool pipe sizes.

No, it only confirms whether the pipe is holding pressure.

We combine camera inspection with vacuum testing for deeper diagnostics.

No, but we provide a more advanced and structured approach than standard testing alone.

If your pool is losing water, your system is not holding pressure, or you are unsure what is causing the issue, HydroTech Pools provides a structured and specialist approach to leak detection.
