Pool Leak Detection in Sydney

Topping the pool up more than you should? We confirm whether it’s really leaking and pinpoint exactly where the water is escaping — shell, fittings or the waterproofing around it.

Pool leak detection

Is your pool actually leaking?

A pool can drop a little from evaporation and splash-out — but a steady loss that has you topping it up every few days usually means water is escaping somewhere it shouldn’t.

We confirm whether it’s a genuine leak first, then trace exactly where it’s going: the shell, a fitting, the plumbing penetrations, or the waterproofing and tiling around the pool and its surrounds.

The problem

Signs your pool is losing water

A few of these together is a strong sign it’s worth checking.

The level keeps dropping

You’re topping up far more than evaporation alone would explain.

Water bills creeping up

A steady, unexplained rise that lines up with the pool loss.

Wet or soggy ground

Damp patches, soft lawn or movement in paving around the pool.

Cracks or movement

New cracks in the shell, coping or surrounding tiled area.

Air in the system

Air bubbles at the returns can point to a suction-side leak.

Algae or chemistry swings

Constant top-ups dilute the water and make it hard to balance.

What’s behind it

What’s usually behind a pool leak

Pool leaks come from a handful of common places. Finding which one is the whole job.

  • A crack or failure in the pool shell or render.
  • A worn or loose fitting — skimmer, return, light or main drain.
  • Leaking plumbing on the pressure or suction side.
  • Failed waterproofing or grout in the tiled waterline and surrounds.
  • Movement or settlement that has opened a join.
How we find it

We confirm it, then pinpoint it

No digging up the yard on a hunch. We work from evidence to the exact point before anything is opened.

  • Confirm the leak — a controlled check tells us whether it’s a genuine leak or evaporation.
  • Isolate the area — we narrow it to the shell, the fittings or the surrounding waterproofing.
  • Pinpoint the source — targeted testing and moisture mapping find the exact escape point.
  • Explain and document — you get a plain-English result, with a report if you need one.

Questions, answered

Pool leak detection — FAQs

How do I know if my pool is leaking or just evaporating?
A simple bucket test gives a rough idea, but the reliable way is a controlled check on site. We confirm whether the loss is a genuine leak before we go looking for the source.
Do you drain the pool to find the leak?
Almost never. We lead with non-invasive methods and targeted testing, so in most cases the pool stays full and the yard stays intact.
How much does pool leak detection cost?
Our first hour on site is $299 inc GST, confirmed as a fixed price before we start. Pool jobs typically run a little higher depending on access and how hidden the source is.
Do you repair the leak too?
We focus on locating and proving the leak accurately, then explain exactly what the repair involves so it can be fixed with confidence.
