Our Leak Detection Methods

Pressure testing gauge icon for pool leak detection

Pressure Testing

One of the most reliable ways to diagnose pool plumbing issues is through pressure testing. This method isolates each underground line - skimmer, return, spa, main drain, water feature, or auto-fill - to see where water loss is taking place.
Why Pressure Testing Matters?
- Finds leaks that cannot be seen at the surface
- Prevents structural damage by catching problems early
- Gives precise results compared to trial-and-error
- Avoids unnecessary digging or repairs.
How We Do It?
Lines are sealed and pressurized with air or water, while gauges monitor any loss. If pressure drops, the leak is confirmed in that line and can be traced for repair. It’s a safe, accurate, and industry-proven method for pool leak detection.

BUCKET TEST

Sometimes the simplest tools are the most effective. The bucket test is designed to show whether water loss is just natural evaporation or the sign of a hidden leak. By comparing the water inside a bucket to the pool itself, the difference becomes clear.
Why the Bucket Test Matters?
- Separates normal evaporation from true leaks.Saves time and money before advanced testing
- Provides dependable results beyond guesswork
- Reduces unnecessary service or repairs
How We Do It?
A bucket filled with pool water is set on a step, marked alongside the pool’s waterline. After 24 hours, the two levels are compared. If the pool drops more than the bucket, a leak is confirmed. It’s quick, accurate, and the standard first step in any professional evaluation.

Hydrophone on a cable inside a pool detecting leaks via sound waves

HYDROPHONE

For leaks hidden in underground plumbing or around fittings, listening technology offers a big advantage. The hydrophone test uses sensitive underwater microphones to detect the exact sound of escaping air or water.
Why Hydrophone Testing Matters?
- Locates leaks that other methods can’t detect
- Allows precise pinpointing without unnecessary digging
- Works even in complex pools with multiple features
- Saves money by speeding up the repair process
How We Do It?
A hydrophone is placed in the pool water while lines are pressurized with air. The device picks up the distinct “hissing” sound made by air escaping through the leak. This advanced acoustic method is highly accurate and a trusted standard in professional leak detection.

Applying dye with a pen near a pool light/tiles to detect leaks

Dye Testing

When leaks are suspected near fittings, lights, or cracks, a dye test is a simple but powerful tool. This approach uses special dye that reveals whether water is being pulled into a suspected problem area.
Why Dye Testing Matters?
- Targets visible cracks, seams, or fittings
- Provides visual proof of a leak
- Works well around lights, drains, and tile lines.Helps confirm where repairs are needed
How We Do It?
A small amount of dye is released near the suspected leak point. If there is suction, the dye is visibly pulled into the crack or opening. This direct method makes it easy to confirm leaks in plaster, grout, or around pool components without invasive work.

ULTRASONIC LISTENING

Some leaks are nearly impossible to locate by sight alone. That’s where ultrasonic listening comes in. This advanced method uses highly sensitive equipment to pick up the faint sounds of water escaping from plumbing lines or structural cracks.
Why Ultrasonic Listening Matters?
- Detects leaks hidden deep in plumbing or concrete
- Avoids unnecessary digging or breaking surfaces
- Works even when other tests provide limited results
- Saves both time and repair costs by pinpointing the leak location
How We Do It?
Specialized listening devices are placed around the pool’s plumbing and structure while the system is pressurized. These instruments capture ultrasonic frequencies created by escaping water or air. By following the sound signature, we can trace the exact location of the leak with high precision, ensuring targeted and effective repair.

FAQ – Pool Leak Detection in Scottsdale, AZ

Q1: How much does pool leak detection cost in Scottsdale?

Basic pool inspection in Scottsdale typically starts at $445, depending on pool size and system complexity. Additional factors like built-in spas, negative edges, or fountains may slightly increase the price. All inspections include a full report, pressure test, and leak location using hydrophone listening equipment.
Q2: How can I tell if my pool is leaking or just evaporating in Scottsdale’s heat?

In Scottsdale’s dry desert climate, normal evaporation is around ¼ inch per day, but during the hottest months it can reach ½ inch or slightly more — especially for heated pools.If you’re losing over 1 inch of water daily or notice damp soil around the equipment pad, that’s usually a leak.A quick way to check is the bucket test, but for certainty, LeakTech’s Scottsdale team can confirm results with pressure and dye testing.
Q3: How long does a professional leak detection take?

Most Scottsdale pool inspections take 1–3 hours, depending on the pool’s size and plumbing layout.Complex systems with attached spas or water features may require additional time for pressure balancing and line isolation.
Q4: What are the most common signs of a pool leak in Scottsdale?

Because of the region’s extreme temperature shifts and soil movement, leaks often appear as:

- Cracks along the pool beam or tile line
- Soft or wet spots in desert landscaping
- Unusual air bubbles in return jets
- Loss of prime in the pump after shutdown
- Higher-than-normal water or chemical usage

If you notice these symptoms, it’s time for a local leak inspection before damage spreads.
Q6: Is leak detection covered by insurance or warranty?

Some homeowner insurance policies in Arizona may cover underground plumbing leaks if they cause property damage.LeakTech provides detailed reports and photos that can be used for your insurance claim.Warranty coverage may also apply if the pool was built or resurfaced recently — we can help document it properly.
