How Professional Leak Detection Works

How Professional Leak Detection Works

If you suspect your swimming pool is leaking, finding the source isn’t always easy. Leaks can be hidden underground, inside walls, under the decking, or deep in the pool structure itself. That’s where professional leak detection comes in. At Four States Leak Detection, we use a combination of specialized tools, techniques, and experience to locate leaks quickly and accurately — saving you time, money, and major headaches.

Here’s a look at how professional pool leak detection works:

1. Visual Inspection
Every leak detection starts with a careful visual inspection. We check for obvious signs like cracks, broken fittings, loose skimmers, damaged tile lines, and wet spots around the pool or equipment pad. Sometimes a leak is visible without needing special equipment — especially in cases of structural cracks or broken plumbing connections.

2. Sonar Listening Equipment
When leaks aren’t visible, we use specialized underwater microphones (called hydrophones) to listen for the sound of water escaping under pressure. These tools can pick up even small leaks in pool shells, plumbing lines, and fittings that the human ear would never detect.

3. Dye Testing
For smaller, hidden leaks around lights, returns, fittings, steps, and cracks, we perform dye testing. A small amount of colored dye is placed near suspected problem areas. If there’s a leak, the dye will be visibly pulled toward the damaged spot, confirming the leak location.

4. Pressure Testing Plumbing Lines
If a leak is suspected in the underground pipes, we isolate each line (returns, skimmers, main drain) and use a pressure rig to test for drops. A properly sealed line should hold pressure — if it doesn’t, we know there’s a break or crack somewhere in that plumbing run.

5. Diving Inspections and Repairs
In cases where leaks are located below the waterline, our trained divers perform hands-on inspections and even some underwater repairs. Diving allows us to closely inspect drains, lights, and surfaces without draining your pool, saving time and minimizing disruption.

6. Video Scoping (Camera Inspection)
For difficult underground plumbing leaks, we can also use waterproof video scopes. These cameras travel through pipes and plumbing systems, giving a live view inside — perfect for finding breaks, cracks, or loose fittings deep inside the system without unnecessary digging.

Why Professional Leak Detection Matters
Trying to guess where a leak is can waste a lot of time, money, and effort. Professional leak detection uses scientific methods, not guesswork, to locate problems accurately — minimizing excavation, saving on water bills, and protecting your pool’s structure.
