Pool Leak Detection Pros provides fibreglass pool repairs in Discovery using a systematic testing process rather than guesswork.
We repair cracks, pinholes and delaminated areas in fibreglass shells after confirming where water is actually escaping, so the fix matches the defect.
Our approach is deliberately non-destructive. We test before we touch anything: suction and return lines are pressure tested, fittings and cracks are dye tested, and underground runs are checked with tracer gas. Only once the leak is confirmed do we recommend opening anything, and only at the exact spot the evidence points to.
A leaking pool in Discovery does not stay the same size. Water escaping underground washes out fine soil, softens the ground and can undermine paving and coping over time. Finding it early is almost always cheaper than waiting for visible damage.
We work by elimination. Each possible leak path, suction line, return line, light, weir, crack, surface or fitting, is tested and either ruled out or confirmed. That produces a defensible finding you can act on, and a quote scoped to the real problem instead of a worst-case guess.
Before assuming the worst, it is worth separating evaporation from a leak. Evaporation tracks the weather and affects most exposed pools similarly; a leak is steadier and may continue when it is cool. If you are unsure, a test settles it without you guessing.
Common signs of a genuine leak rather than evaporation in Discovery include:
We focus on leak detection and pool repair specifically, not general pool cleaning, so the testing methods and judgement come from doing this work day in and day out across Gauteng and the surrounding provinces.
To get started in Discovery, send photos of the pool and pump, tell us how fast the water is dropping and whether the pump is running when it happens. That lets us confirm the right approach and a fair price before we arrive.
The correct repair depends on whether water loss is coming from the pool shell, suction line, return line, light niche, weir, aimflow jet, equipment station or deteriorated finish.
Repairing a pool without confirming the leak source can waste money. A leaking return line will not be solved by resurfacing, and a porous pool shell will not be solved by replacing one pipe. We narrow the cause before recommending repair.
We begin with a visual inspection and symptom review. Where plumbing is suspected, suction and return lines are isolated and pressure tested. Where structural or fitting leaks are suspected, dye testing is used around the relevant areas. Tracer gas may be used for underground leaks where the pipe route and conditions allow accurate location.
The outcome is a practical recommendation: localised repair, pipe replacement, fitting repair, crack repair, fibreglass lining, re-marblelite or full renovation depending on what the evidence shows.
A pool leak is likely when water loss is faster than normal evaporation, especially if the level drops overnight, the pump loses prime, bubbles return through the aimflows or wet ground appears around the pool.
A visible fitting leak can sometimes be quoted from photos, but hidden underground or structural leaks should be tested first. Guessing often leads to repairing the wrong area.
No. Many leaks are found at lights, aimflow jets, weirs, cracks or deteriorated pool finishes. Digging should only happen after the leak position has been narrowed down.
Yes. Old, porous, cracked or hollow marblelite can allow water loss through multiple small openings, especially when the finish has reached the end of its service life.
Yes. Pinholes, delamination, poorly sealed fittings and cracks can cause fibreglass pools to lose water.
The investigation may include visual inspection, pressure testing, dye testing, tracer gas and process-of-elimination checks depending on the symptoms.
Yes. Leaks that worsen when the pump is running often involve return lines, pressure-side plumbing, aimflow jets or equipment connections.
Yes. Leaks while the pump is off often point to the shell, light niche, weir, fittings, cracks or static plumbing leaks below water level.
Yes. Findings can be provided with a technical summary and repair recommendations for homeowners, body corporates or insurance purposes.
Once the leak source is identified, the repair is quoted separately with a recommended scope based on the confirmed cause of water loss.
