✔ Pressure Testing Available
✔ Underground Plumbing Diagnostics
What Is Pool Leak Detection?
Leak detection is the process of determining where your pool is losing water.
This may include checking:
- Vinyl liners
- Concrete shells
- Pool fittings
- Skimmers
- Main drains
- Return fittings
- Lights
- Underground plumbing
Our goal is to determine whether the leak is coming from:
- The pool structure itself
- The liner
- A fitting or gasket
- Underground pipes
Vinyl Liner Leak Detection
Over time, liners can develop:
- Small punctures
- Seam separation
- Tears
- Leaks around fittings
- Step section leaks
- Main drain leaks
- Skimmer gasket leaks
We inspect the liner carefully and use professional leak detection methods to help locate the leak source.
Common Areas We Check
- Skimmer area
- Return fittings
- Corners & seams
- Main drain
- Steps
- Faceplates & gaskets
- Visible wrinkles or movement
Concrete Pool Leak Detection
Concrete pool leaks may come from:
- Structural cracks
- Expansion joints
- Plumbing penetrations
- Light niches
- Main drains
- Return lines
Concrete pools requires a different diagnostic approach than liner pools due to the rigid structure.
Pressure Testing for Underground Plumbing
If we suspect the leak may be underground, we also provide professional pressure testing services.
Pressure testing checks whether:
- Skimmer lines leak
- Return lines leak
- Main drain lines leak
- Underground plumbing is compromised
We use professional Anderson pressure testing equipment to isolate and test plumbing lines individually.
Important:
Leak detection and pressure testing are two different services.
Leak Detection
Checks:
- Liner leaks
- Concrete shell leaks
- Fittings & visible leak sources
Pressure Testing
Checks:
- Underground plumbing lines
- Hidden pipe leaks beneath the ground
In some cases, both services may be recommended.
FAQ
Can liner leaks be repaired?
Many liner leaks can be patched depending on the condition on your liner & location.
Note: we limit to 2 patches per leak detection; if more tears are found. We require a liner replacement
Can multiple leaks exist?
Yes. Some pools may have more than one leak source.
Do you replace liners if needed?
Yes. We also specialize in vinyl liner replacements throughout Montreal.
My pool only loses water while the pump is running. What do I need?
This usually points toward an underground plumbing leak, meaning a pressure test is often recommended.
My pool loses water even when the equipment is off. What does that mean?
This is more commonly associated with a liner leak, concrete shell leak, or leaking fitting rather than underground plumbing.
The water always stops dropping at the same level. Is that important?
Yes. When the water consistently stops at the same height, the leak is often located around that water level — commonly the liner, skimmer, return, or light area.
I see air bubbles coming from my return jets. What could that mean?
Air bubbles can indicate a plumbing issue or underground suction-side leak, which may require pressure testing.
Can underground plumbing leaks and liner leaks happen at the same time?
Yes. Some pools have both a liner leak and underground plumbing leak simultaneously.
