When deciding who to call about a leaking pool, act fast to protect your pool and property. A pool leak detection service uses specialized tools to confirm a leak and find its exact location. Some companies detect and repair; others detect only, so repairs may require a pool repair company.

Watch for excessive water loss, unbalanced watering, or soggy spots on the lawn. Unchecked leaks can lead to cracks and structural issues.

Benefits of Hiring a Pool Leak Detection Service to Detect a Pool Leak

Hiring a pool leak detection service is the fastest, most reliable way to confirm a true leak and locate it. Pros use advanced tools to pinpoint leak locations efficiently, often the same day. Quick repairs help avoid high water bills and prevent structural damage. Some companies offer both detection and repair, while others focus solely on leak detection.

Here are some of the top benefits of hiring a leak detection pro:

• Confirms an accurate leak versus evaporation, heat, or a faulty pool cover

• Uses a leak analyzer to detect minute water-level changes

• Pressure testing pinpoints plumbing leaks accurately

• Electronic listening equipment locates underground bubbling from leaks

• Underwater hydrophone identifies structural leak locations in the pool

• Electronic detector finds vinyl liner leak points precisely

• Same-day leak location enables immediate repair planning

• Reduces DIY guesswork and multiple trial-and-error attempts

• Helps prevent cracks and costly structural problems

• Minimizes wasted water and chemical imbalance

If the leak is severe or you’re unable to pinpoint the source, you might want to consider a pool repair pro near you to ensure the job is done safely and efficiently.

Can I Hire a Pool Maintenance Service to Detect a Pool Leak?

Some pool maintenance companies also offer leak detection, but not all do. Ask your maintenance provider whether they perform leak detection so you understand their scope. 

Ongoing maintenance helps prevent leaks and equipment issues by keeping systems in good condition. If you suspect a leak, a dedicated leak detection service ensures fast confirmation and precise location. Repairs may still require a pool repair company if maintenance does not handle fixes.

How Do Pros Detect a Pool Leak?

Pros follow a clear process to confirm and find pool leaks quickly:

1. Confirm a leak using a leak analyzer (a rapid water-loss sensor).

2. Pressure test plumbing lines to identify pressure drops that indicate leaks.

3. Use electronic listening equipment above ground to trace bubbling sounds to exact points.

4. Deploy underwater listening gear (a hydrophone) to home in on “whooshing” sounds in the pool.

5. For vinyl liners, apply an electronic leak detector to track current flow to the leak point.

A leak analyzer detects water level changes as small as 10,000th of an inch. Pros can confirm a leak within minutes and locate it the same day.

How Much Does Pool Leak Detection Cost?

Leak detection services cost $100 to $500, depending on the security of the leak and its location. Once the leak is identified, repairs can cost between $240 and $1,160, depending on the extent of the damage. DIY repair kits can start at $20, but aren’t effective for most jobs.
