Book a pool or spa leak investigation

Pool Leak Detection Sydney

Pool needs constant topping up? We investigate leaking pools and spas across Greater Sydney with pipe pressure testing, underwater inspections and targeted dye testing, using acoustic listening where suitable.

Call with your suburb, pool type and how quickly the water level drops. We confirm the testing scope, price and attendance availability before you book. Repairs are discussed separately.

Pool Leak Detection in Sydney – Real Job Videos

Pool leaks can come from the pool shell, cracked tiles, skimmer boxes, return fittings, lights, hydrostatic valves or underground suction and return lines. The water loss is not always visible from the surface, so we work through the system methodically instead of guessing. These real Sydney job videos show the kinds of faults we investigate in concrete, tiled and spa systems, including a leaking hydrostatic valve casing in Greenacre and a broken spa line in Granville.

Our testing may combine pipe pressure testing, targeted dye testing, underwater inspection and acoustic listening equipment, depending on how the pool is losing water. We isolate the shell, plumbing lines and pool equipment to narrow down the affected area before recommending a repair. Sydney Plumbing Empire attends pool and spa leak investigations across Greater Sydney, including Greenacre, Granville, Marrickville, the Inner West, Canterbury-Bankstown, Western Sydney, the Eastern Suburbs, the North Shore and the Sutherland Shire.

Hydrostatic valve casing leak – Greenacre

Underwater dye movement confirmed the leak at the hydrostatic valve casing, allowing the repair area to be identified without guessing.

Acoustic pool leak location – Granville

Acoustic listening equipment was used to narrow down the position of a broken underground spa line before targeted repair work.

Broken spa line found – Granville

The shorter job clip shows the Granville spa investigation where acoustic testing helped locate the failed line beneath the surrounding area.

Pool Leak Detection Sydney FAQs

How do you find leaks in a pool?

We isolate the pool shell, plumbing and equipment, then use the appropriate combination of pressure testing, targeted dye testing, underwater inspection and acoustic listening. This helps identify whether the loss is coming from tiles, fittings, a skimmer, return lines, a hydrostatic valve or underground pipework.

Can you test a pool without draining it?

Yes. Many pool fittings, lights, skimmers, hydrostatic valves and visible shell defects can be inspected and dye tested while the pool remains full. The testing method depends on the pool type, access and the pattern of water loss.

What equipment do you use for pool leak detection?

Depending on the symptoms, we may use pressure-testing equipment, pool plugs, targeted dye, an underwater camera and acoustic listening equipment. We select the equipment needed to separate plumbing-line leaks from shell, fitting and equipment faults.

Which Sydney suburbs do you service?

We service pool and spa leak investigations across Greater Sydney, including Greenacre, Granville, Marrickville, the Inner West, Canterbury-Bankstown, Western Sydney, the Eastern Suburbs, North Shore and Sutherland Shire.

Where pool leaks hide

Pool leaks commonly occur in the shell, skimmer box, return fittings, light niche, hydrostatic valve, tile line, underground pipework or at the pump and filtration equipment.

Guessing which one it is — and digging up pavers or pipework on a hunch — is expensive and often wrong. We test systematically so repairs are targeted to the actual fault.

Our testing methods

  • Pressure testing to isolate leaking sections of pipework
  • Dye testing to visually confirm cracks and gaps in the shell
  • Underwater dive inspection of fittings, lights, valves and cracks
  • Hydrostatic valve and skimmer box leak testing
  • Equipment inspection covering pumps, filters, valves and unions

How we find your pool leak

01

Confirm the loss

We assess the water-loss pattern and inspect the pool and equipment for visible signs.

02

Isolate the system

Pipework is pressure tested so leaking lines can be separated from the pool shell.

03

Test underwater

Dye and dive testing checks lights, skimmers, returns, valves, fittings and suspected cracks.

04

Pinpoint the fault

You receive a clear explanation of the leak location and the appropriate repair pathway.

Choose the test that matches the problem

Signs your pool may be leaking

  • Needing to top up the pool more often than usual
  • A noticeable overnight water-level drop
  • Wet soil, paving movement or unexplained water near the pool
  • Air entering the pump or difficulty maintaining prime
  • Cracks, loose tiles or deterioration around pool fittings

Pools and systems we test

  • Concrete, tiled and fibreglass swimming pools
  • Spas, balance tanks and attached water features
  • Skimmer, return, cleaner and main-drain lines
  • Pool lights, hydrostatic valves and equipment pads
  • Residential, strata and commercial pool systems

Stop the water loss

Evaporation changes with heat, wind and pool use, but repeated top-ups or a sudden drop should be investigated. We identify whether the loss is from the shell, pipework or equipment so the repair targets the actual fault.

Leaking pool or normal evaporation?

Heat, wind and pool use affect normal water loss. A falling level alone does not identify a failed pipe or fitting. Our pool losing water guide explains a bucket comparison and the observations that help narrow down the cause.

Repeated top-ups, an unusual overnight drop or wet ground around the pool are reasons to arrange testing. Avoid repeatedly adding leak-sealing products before an inspection without discussing the system and symptoms.

What to tell us before a pool inspection

  • Your suburb and whether it is a pool, spa or connected system
  • How quickly the level falls and whether it stops at a particular fitting
  • Whether the loss changes with the pump running or switched off
  • Any recent repairs, pool works or products added to the water
  • Access to the equipment and any previous pressure-test results

Inspection scope, line count, access and any repair work are confirmed when booking. Testing and repair can be separate visits.
