Pool leak detectors : locate the source of water loss with precision

Every day a leak goes undetected, your pool drains, your treatment weakens, and your costs rise. Our pool leak detection solutions are designed with one clear goal: to save you diagnostic time and reduce interventions to the essentials. Whether you are a demanding homeowner or a maintenance professional, Fluotracking provides tested and proven leak detection tools for pools: fluorescein dye and UV lamps to visualise flow, pipe stoppers and plugs to isolate sections, and pressure testing accessories to confirm results.

The result : you identify the precise origin of a leak (skimmer, return jet, main drain, fittings, liner, steps, or joints), prioritise repairs, and stop the costly loss of water and treatment chemicals.

How to choose your pool leak detector according to pool type

A good pool leak detector is not a one-size-fits-all gadget — it’s a tool adapted to your pool material, symptoms, and access conditions.

Liner pools : track micro-perforations without draining the water

Pool liners are comfortable and aesthetic, but they are also sensitive to micro-tears — often caused by ladders, robots, toys or fittings. The most reliable method remains fluorescein dye + UV lamp. Turn off filtration and keep the water still, then inject a small drop of fluorescein dye near the suspected area. If the liner draws it in, the yellow-green stream flows toward the leak — an instant visual confirmation.

For systematic inspection, follow seams, skimmer gaskets, projector seals, vacuum fittings, and corners.

Pro tip : prepare two syringes — one for upper areas (skimmers, returns), the other for the bottom and angles. At the end of the session, use the UV lamp to confirm marked points and take photos for your report or insurance documentation.

Fibreglass or polyester pools : fittings, seals and pipework

On polyester or fibreglass shells, leaks often occur around sealed fittings, bonding areas, or within pipes. Combine fluorescent dye tracing (visible side) with pressure line testing (hidden side). Using inflatable pipe stoppers, isolate a return line or vacuum line, apply light pressure from the equipment side, and monitor for pressure drop — the leaking circuit will reveal itself. The dye will then confirm the point of entry or exit on the wall.

Concrete or tiled pools : joints, penetrations and waterproofing repairs

Concrete or tiled pools are prone to leaks at aged joints, wall penetrations, or built-in stairs. The best practice combines visual inspection and fluorescein testing directly on cracks or joints, followed by pressure testing of the hydraulic lines. Don’t forget overflow channels and balance tanks — an unstable water level may mask a peripheral leak.

Pipework : isolate, pressurise, and eliminate doubt quickly

When the water level drops without visible cause, the pipework is often responsible. The winning approach:

• Seal off each line (skimmer, return, main drain) using stoppers.
• Apply controlled pressure (or vacuum) and measure pressure loss over time.
• Reopen progressively: once a line drops pressure, you’ve isolated the leak zone.

This method avoids random excavation and limits repair work to the precise location of the fault.

Two core methods for pool leak detection : visual and measurable

The goal isn’t to guess — it’s to document and prove. Here are the two main pillars of effective and reliable pool leak diagnostics.

1. UV dye test : proof by visual evidence

• When to use: For suspected leaks on liners, fittings or joints.
• How: Stop filtration, let the water settle, and inject the dye 1–2 cm from the target area. Observe the flow carefully.
• What it proves: If the dye stream is drawn in, there’s a leak path — a micro-crack, joint defect, or pinhole.
• Advantages: Fast, inexpensive, and highly visual — ideal for documentation and pre-repair diagnosis.
• Limitations: Requires calm water and close access, which is why a systematic inspection is recommended.

2. Pressure testing for leak detection

• Purpose: To confirm or rule out leaks in buried pipework without breaking ground.
• Method: Use a pressure testing kit with inflatable plugs to isolate lines, apply pressure, and monitor stability over time.
• Reading results: A pressure drop indicates a leak — whether from a fitting, joint or fractured pipe.
• Benefit: Enables precise intervention — excavation or repair only where necessary.
