Is Your Pool Level Dropping?
If your pool water keeps dropping and you can’t figure out why, chances are there’s a hidden leak somewhere. It might be a cracked pipe underground, a loose fitting or a small split in the pool shell.
At Leaks Downunder, we use sonar leak detection to find the problem quickly without draining your pool or digging up your yard. Because we’re run by a licensed plumber, we can repair the leak properly once it’s found. That means one visit, one expert, and no guesswork. You’ll get clear answers, honest advice, and a lasting fix that keeps your pool watertight. Our service area covers North Lakes, Bribie Island and Caboolture, extending to the Sunshine Coast and Brisbane.

How can I tell if my pool is leaking or just evaporating?
To tell if your pool is leaking or just evaporating, mark the water level and check it the next day. If it drops more than a few millimetres, you’re dealing with a leak, not evaporation.
Do you need to dig to find a leak?
We usually don’t need to dig to find a leak. With sonar and pressure testing, we can detect leaks through soil or concrete without damaging your pool area.
Can you fix the leak once it’s found?
Yes, we can typically fix the leak once it’s found. Because Leaks Downunder is run by a licensed plumber, we can handle the detection and the repair.
Our Leak Detection Process
If you’re not sure how pool leak detection works, here’s a quick rundown. Every job starts with a visual check, and from there we use a mix of testing and sonar technology to track down the leak with precision.
- Visual Inspection – We start by inspecting the pool shell, fittings and equipment for any obvious signs of a leak. With over 40 years of experience, a quick look can often point us in the right direction.
- Pressure Testing – If nothing stands out visually, we pressure-test the pipes to see if any lines are losing water. This tells us exactly which section of pipework needs a closer look.
- Sonar Leak Detection – Once we’ve narrowed it down, we use underwater ultrasound equipment to listen for the sound of escaping water. This allows us to locate the exact point of the leak without digging or draining.
- Reporting and Repair Options – After we’ve found the problem, we’ll explain what’s going on and outline the best options for repair. As a licensed plumber, we can typically carry out the fix if you’d like.
