Common symptoms

  • Pool losing water overnight
  • Air bubbles from return jets
  • Pump losing prime

Pool Pipe Repairs in Weltevreden Park

Once the failing section is located by testing, we repair only the confirmed length of pipe, so you are not paying to open paving on guesswork.

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.

Why act early

A leaking pool in Weltevreden Park 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.

How we find it

A typical visit follows a clear sequence: a visual inspection of the shell, paving, pump and fittings; isolation and pressure testing of the plumbing lines; dye testing around suspected openings; and, where an underground pipe is implicated, tracer-gas tracing. You receive a plain explanation of what was found and what the repair involves.

Is it a leak or evaporation?

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.

It may be worth booking a test if you are seeing any of these in Weltevreden Park:

Why homeowners and estates choose us

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.

Send your Weltevreden Park address, the pool symptoms and a short video or photos of the water level and pump. We will come back to you with the likely cause and what the visit involves.

Technical pool pipe repairs in Weltevreden Park

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.

What we check

  • Water-loss pattern with the pump on and off.
  • Suction and return pipework where plumbing leaks are suspected.
  • Pool lights, aimflow jets, weirs, steps and visible cracks.
  • marblelite porosity, fibreglass pinholes and surface failure.
  • Pump station, valves, unions and filter connections.

Why testing matters

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.

Our process in Weltevreden Park

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.

Frequently asked questions

How do I know if my pool is leaking?

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.

Can you quote a repair without testing first?

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.

Does every leak require digging?

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.

Can marblelite cause water loss?

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.

Can fibreglass pools leak?

Yes. Pinholes, delamination, poorly sealed fittings and cracks can cause fibreglass pools to lose water.

What testing methods are used?

The investigation may include visual inspection, pressure testing, dye testing, tracer gas and process-of-elimination checks depending on the symptoms.

Can a pool leak only when the pump is running?

Yes. Leaks that worsen when the pump is running often involve return lines, pressure-side plumbing, aimflow jets or equipment connections.

Can a pool leak when the pump is off?

Yes. Leaks while the pump is off often point to the shell, light niche, weir, fittings, cracks or static plumbing leaks below water level.

Do you provide reports?

Yes. Findings can be provided with a technical summary and repair recommendations for homeowners, body corporates or insurance purposes.

What happens after detection?

Once the leak source is identified, the repair is quoted separately with a recommended scope based on the confirmed cause of water loss.

More pool leak questions

Quick answers to questions we are often asked. All 56 are on our pool leak FAQ page.

Can a swimming pool leak underground?

Yes. Underground suction and return lines can leak due to failed joints, ground movement, age, poor installation, root movement or previous repairs. These leaks are usually not visible from the surface and may only show as wet soil, sinking paving, air in the pump or unexplained water loss. Pressure testing and tracer gas can help narrow down the underground failure point.

Do all leaks require pipe replacement?

No. Some leaks are at fittings, lights, weirs, cracks or surface defects. Some pipe leaks can be repaired locally if the damaged section is accessible and the rest of the line is sound. Full replacement is usually considered where pipework is badly routed, brittle, repeatedly failing or not practical to repair locally.

When should pool pipes be replaced instead of repaired?

Replacement may be recommended where pipes are old, brittle, poorly installed, leaking in multiple places, inaccessible for reliable local repair, or where previous repairs have failed. The decision should be based on test results, site conditions and long-term reliability, not just the cheapest immediate patch.

Can tree roots damage pool pipes?

Tree roots can contribute to pipe displacement, joint stress and movement around underground services. Roots usually exploit weak points rather than cutting through strong pipe by themselves, but older or poorly installed plumbing is more vulnerable.

Can a leaking pool pipe damage the pump?

Indirectly, yes. A suction leak can cause air ingress, cavitation and poor flow. A return leak can reduce circulation efficiency and waste water. Running a pump with air in the system or insufficient flow can shorten equipment life and increase repair costs.

Can pool leaks cause paving to sink?

Yes. Water escaping underground can wash away fine material, soften soil and undermine paving or coping. Over time, this may lead to movement, hollow areas, cracks or settlement around the pool. This is one reason leaks should be detected early.
