Pool & Spa Plumbing
Pool & Spa Leak Detection
Losing water from a pool or spa gets expensive fast — in water, chemicals, heating and eventually structural damage. We use precise, non-invasive leak detection to find the exact fault before anyone starts digging.
Non-invasive detection
Find the leak without wrecking the backyard
Guesswork excavation is what makes pool leaks expensive. We test the shell, the fittings and every buried line first, so the repair is targeted to one spot instead of a trench across your lawn. You'll know what's leaking, why, and what it costs to fix before we lift a shovel.

Why pools leak
Common causes of pool & spa leaks
Cracked or shifting pool shells
Concrete and fibreglass shells crack as the ground moves, opening slow leaks that get worse over time.
Damaged pipework
Suction and return lines crack, split or pull apart at joints, often metres away from the pool itself.
Faulty fittings, valves and seals
Perished O-rings, worn pump seals and failed valves leak constantly while the system is running.
Worn skimmer boxes or main drains
Skimmer throats and main drain fittings separate from the shell — one of the most common leak points we find.
Poor installation or ageing infrastructure
Badly glued joints, undersized pipework and decades-old systems eventually give way.
Ground movement or tree root intrusion
Roots and soil movement crush and displace buried lines, especially in older Sydney backyards.

Our leak detection process
- 1
Initial Assessment
We inspect the pool, spa, equipment and surrounds, review your top-up history and rule out evaporation with a bucket test where needed.
- 2
Pressure Testing
Each suction and return line is isolated and pressure tested so we know exactly which line is losing water before anything is dug up.
- 3
Acoustic & Electronic Detection
Acoustic listening gear and electronic leak detection trace the escaping water to a precise point underground or in the shell.
- 4
Dye Testing & Visual Inspection
Dye testing confirms leaks at skimmers, lights, main drains and hairline cracks that pressure testing alone won't isolate.
- 5
Clear Diagnosis & Report
You get a plain-English report showing where the leak is, what caused it, and a fixed-price option to repair it.
